Aligning Treatment Goals with Technological Advances

* The interplay between orthodontic forces and periodontal tissues in young patients.

Okay, so we're talking about kids' teeth, right? And not just making them look pretty, but making sure they work well and last a lifetime. Pediatric orthodontics, it's more than just a straight smile. It's setting the stage for a healthy mouth down the road. We're thinking about aesthetics, sure. Some orthodontic issues are inherited while others develop over time Dental braces for children disease. A confident kid is a happy kid, and a nice smile plays a role in that. But function is huge. Can they chew properly? Is their bite even? Are they going to grind their teeth? These things impact their overall well-being. And then, of course, there's the long game: preventing problems like gum disease, tooth decay, and even TMJ issues later in life.


Now, throw into the mix all the cool new tech we've got. We're not just talking about metal braces anymore. We've got clear aligners, digital scanners that replace those goopy impressions, 3D printing for custom appliances… it's a whole different ballgame. The trick is to not get so caught up in the whiz-bang gadgets that we forget what we're actually trying to achieve. It's about using these advancements strategically to reach those three core goals: aesthetics, function, and long-term health. Maybe clear aligners are perfect for a teen self-conscious about braces, helping them achieve that confident smile. Perhaps a digital scanner allows for a more precise appliance, improving function. Or maybe a specific 3D-printed retainer can help maintain that alignment and prevent future problems. The tech is just a tool. It's how we use that tool to meet the individual needs of each child that really matters. It's about weaving the technology seamlessly into a treatment plan that prioritizes not just a pretty smile today, but a healthy, functional mouth for years to come.

Alright, let's talk about how all this cool new tech is changing orthodontics. I mean, think about it – straightening teeth used to be, well, pretty analog. Now? We're talking digital imaging, 3D printing, and materials that sound like they belong in a sci-fi movie. The big question is, how does all this shiny stuff actually help us achieve better results and a happier patient?


Basically, it boils down to precision, predictability, and personalization. Digital imaging, like those fancy cone-beam CT scans, gives orthodontists a much more detailed and accurate picture of what's going on inside your mouth. It's not just about seeing where the teeth are; it's about understanding the bone structure, nerve pathways, and other crucial details. This allows for more accurate diagnoses and treatment planning.


Then there's 3D printing. Forget clunky, one-size-fits-all braces. Now, we can print custom aligners and appliances that perfectly fit your teeth, making treatment more comfortable and efficient. It's like having a tailored suit for your teeth! Plus, the ability to visualize and plan the entire treatment process in 3D beforehand means fewer surprises along the way.


And let's not forget the materials! We're talking about shape-memory alloys for wires that gently guide teeth into place, and advanced ceramics for brackets that are less noticeable and more comfortable. These new materials are not only more aesthetically pleasing but also often require fewer adjustments, meaning less time in the orthodontist's chair.


Ultimately, the advancements aren't just about having cooler gadgets. They're about aligning treatment goals – a straighter smile, improved bite, better oral health – with the technology that allows us to achieve those goals more effectively and comfortably than ever before. It's a win-win for everyone!

Aligning Treatment Goals with Technological Advances:


We all want the best possible outcome when it comes to healthcare, right? And that "best" often means a few key things: quicker treatment, less discomfort, and ultimately, a better quality of life while we're undergoing that treatment. It's about making the process as seamless and humane as possible. Thankfully, technology is stepping up to the plate in some seriously impressive ways, helping us align those deeply personal treatment goals with tangible, innovative solutions.


Think about it. Traditionally, some medical procedures could be lengthy and, let's be honest, pretty uncomfortable. But now, minimally invasive surgery, powered by advanced imaging and robotic assistance, is drastically cutting down recovery times. Patients are getting back on their feet faster, experiencing less pain, and spending less time in the hospital. That's a win-win-win!


And it's not just about surgery. Consider the advancements in radiation therapy. Techniques like intensity-modulated radiation therapy (IMRT) allow doctors to precisely target cancerous cells while minimizing damage to surrounding healthy tissue. This means fewer side effects and a more comfortable experience for patients battling cancer.


Even something as seemingly simple as virtual reality (VR) is making a difference. VR is being used to help patients manage pain, reduce anxiety during procedures, and even rehabilitate after injuries. It's a powerful tool that can distract, engage, and ultimately, empower patients to take control of their treatment experience.


The beauty of all this is that it's not just about shiny new gadgets. It's about understanding the patient's needs and then strategically deploying technology to meet those needs. It's about making treatment more efficient, more bearable, and ultimately, more effective. As technology continues to evolve, we can expect even more innovative solutions that further blur the lines between what was once considered science fiction and the reality of modern healthcare. The future of treatment is personalized, precise, and, most importantly, human-centered, all thanks to the clever application of technological progress.

Aligning Treatment Goals with Technological Advances: Benefits and Limitations in Pediatric Orthodontics


The playground of pediatric orthodontics is increasingly filled with shiny new toys – advanced technologies promising faster, more efficient, and more comfortable treatment. From 3D printing of aligners to sophisticated imaging techniques, these innovations offer exciting possibilities for straightening smiles and improving oral health in children. However, like any game, it's crucial to understand the rules, the potential pitfalls, and whether the tool truly serves the ultimate purpose: the well-being of the young patient.


The benefits are undeniable. Advanced imaging, such as cone-beam computed tomography (CBCT), provides a far more detailed view of a child's craniofacial structures than traditional X-rays, allowing for more precise diagnoses and treatment planning. This is particularly crucial in cases involving impacted teeth or complex skeletal discrepancies. 3D printing empowers orthodontists to create customized appliances, like clear aligners, that fit perfectly and potentially reduce discomfort. Furthermore, these technologies often streamline the treatment process, potentially shortening the overall duration and reducing the number of appointments required. Imagine a child spending less time in the orthodontist's chair and more time enjoying being a kid – that's a significant win.


However, the allure of the new shouldn't blind us to the limitations. Cost is a major factor. Advanced technologies often come with a hefty price tag, which can make them inaccessible to some families. Furthermore, the learning curve for these technologies can be steep, requiring orthodontists to invest in significant training and equipment. This investment, ultimately, may be passed on to the patient. More importantly, the reliance on technology should never overshadow the importance of clinical judgment. A sophisticated 3D model is only as good as the orthodontist interpreting it. Over-reliance on automated systems could lead to a disconnect from the individual needs of the child and potentially result in a cookie-cutter approach to treatment.


Finally, there are considerations regarding radiation exposure, particularly with CBCT. While the radiation dose is generally low, it's crucial to weigh the benefits against the risks, especially in young children. The "as low as reasonably achievable" (ALARA) principle should always be paramount.


In conclusion, advanced technologies offer tremendous potential to enhance pediatric orthodontic care. However, they are tools, not panaceas. Careful consideration of the benefits, limitations, costs, and potential risks is essential. The ultimate goal should always be to align these technological advancements with the individual needs and treatment goals of each child, ensuring that the pursuit of a perfect smile doesn't come at the expense of their overall health and well-being. The best approach is a balanced one, combining the power of technology with the art and science of orthodontics, guided by the experienced hand and discerning eye of a skilled clinician.

Let's be honest, talking about "aligning treatment goals with technological advances" can sound a bit robotic, right? We're not just plugging kids into machines and hoping for the best. It's about finding ways technology can genuinely help them achieve their goals, whatever those might be. So, let's look at some real-life examples, some stories that show how technology is making a difference.


Think about a young child with autism spectrum disorder struggling with social interaction. Traditional therapy is vital, but technology can offer powerful supplementary tools. For instance, specialized apps and virtual reality scenarios can create safe, predictable environments where the child can practice social skills like initiating conversations or understanding facial expressions. One study showed kids using a VR program to navigate a virtual classroom felt more confident and less anxious in a real-world setting. That's not just about the tech; it's about building confidence and independence.


Or consider a teenager battling depression. While talk therapy remains crucial, wearable technology like mood-tracking apps and even smartwatches can provide valuable insights. These tools can help the teen and their therapist identify patterns in their mood swings, pinpoint triggers, and develop personalized coping strategies. The data isn't a replacement for human connection, but it can empower the teen to take an active role in understanding and managing their mental health.


Then there's the example of a young athlete recovering from a sports injury. Physical therapy is essential, but advanced motion capture technology and biofeedback systems can provide real-time feedback on their movements, ensuring they're performing exercises correctly and preventing re-injury. This isn't just about getting back on the field faster; it's about a safer, more informed recovery process.


The common thread here is that technology isn't the solution on its own. It's a tool. A powerful tool, yes, but one that needs to be thoughtfully integrated into a holistic treatment plan. It's about understanding the specific goals of the young patient, and then finding the technological advancements that can best support them on their journey. It's about using technology to empower them, to give them agency, and ultimately, to help them thrive. And that, at its heart, is a very human endeavor.

Aligning Treatment Goals with Technological Advances: Future Directions


Orthodontics for children has always been about more than just straight teeth. It's about fostering confidence, improving oral health, and setting the stage for a lifetime of smiles. But the landscape of treatment is shifting, driven by a wave of exciting new technologies. So, where are we headed? What does the future hold for our young patients?


One promising area is in diagnostics. Imagine a world where we can predict growth patterns with incredible accuracy using AI-powered cephalometric analysis. No more guessing about how a child's jaw will develop – we'll have data-driven insights to guide treatment planning from the very beginning. This means more efficient treatment, less reliance on invasive procedures, and ultimately, better outcomes.


Then there's the realm of 3D printing and custom appliances. Forget clunky, uncomfortable braces. We're talking about virtually invisible aligners tailored perfectly to each child's unique dental anatomy, created with pinpoint precision. These aligners can not only straighten teeth more discreetly but also potentially address complex malocclusions with greater efficacy and comfort.


The rise of telehealth is also poised to revolutionize orthodontic care. Remote monitoring using smartphone apps and intraoral scanners can allow orthodontists to track progress more closely, reducing the need for frequent in-office visits. This is particularly beneficial for children with busy schedules or for those who live in remote areas.


However, it's crucial to remember that technology is a tool, not a replacement for clinical judgment. We need to be mindful of the ethical implications of these advancements, ensuring that technology serves the best interests of the child and doesn't simply become a means of maximizing efficiency. The human element – the empathy, the careful observation, the personalized care – must remain at the heart of orthodontic practice.


Looking ahead, the key is to thoughtfully integrate these emerging technologies into our treatment plans. We need to embrace innovation while remaining grounded in sound clinical principles, always keeping the child's well-being and long-term oral health as our top priorities. By aligning our treatment goals with the potential of technological advances, we can create a future where every child can achieve a healthy, beautiful smile with greater comfort, efficiency, and predictability.

A child (pl.children) is a human being between the stages of birth and puberty,[1][2] or between the developmental period of infancy and puberty.[3] The term may also refer to an unborn human being.[4][5] In English-speaking countries, the legal definition of child generally refers to a minor, in this case as a person younger than the local age of majority (there are exceptions like, for example, the consume and purchase of alcoholic beverage even after said age of majority[6]), regardless of their physical, mental and sexual development as biological adults.[1][7][8] Children generally have fewer rights and responsibilities than adults. They are generally classed as unable to make serious decisions.

Child may also describe a relationship with a parent (such as sons and daughters of any age)[9] or, metaphorically, an authority figure, or signify group membership in a clan, tribe, or religion; it can also signify being strongly affected by a specific time, place, or circumstance, as in "a child of nature" or "a child of the Sixties."[10]

In the biological sciences, a child is usually defined as a person between birth and puberty,[1][2] or between the developmental period of infancy and puberty.[3] Legally, the term child may refer to anyone below the age of majority or some other age limit.

The United Nations Convention on the Rights of the Child defines child as, "A human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier."[11] This is ratified by 192 of 194 member countries. The term child may also refer to someone below another legally defined age limit unconnected to the age of majority. In Singapore, for example, a child is legally defined as someone under the age of 14 under the "Children and Young Persons Act" whereas the age of majority is 21.[12][13] In U.S. Immigration Law, a child refers to anyone who is under the age of 21.[14]

Some English definitions of the word child include the fetus (sometimes termed the unborn).[15] In many cultures, a child is considered an adult after undergoing a rite of passage, which may or may not correspond to the time of puberty.

Children generally have fewer rights than adults and are classed as unable to make serious decisions, and legally must always be under the care of a responsible adult or child custody, whether their parents divorce or not.

Developmental stages of childhood

[edit]

Early childhood

[edit]

Early childhood follows the infancy stage and begins with toddlerhood when the child begins speaking or taking steps independently.[16][17] While toddlerhood ends around age 3 when the child becomes less dependent on parental assistance for basic needs, early childhood continues approximately until the age of 5 or 6. However, according to the National Association for the Education of Young Children, early childhood also includes infancy. At this stage children are learning through observing, experimenting and communicating with others. Adults supervise and support the development process of the child, which then will lead to the child's autonomy. Also during this stage, a strong emotional bond is created between the child and the care providers. The children also start preschool and kindergarten at this age: and hence their social lives.

Middle childhood

[edit]

Middle childhood begins at around age 7, and ends at around age 9 or 10.[18] Together, early and middle childhood are called formative years. In this middle period, children develop socially and mentally. They are at a stage where they make new friends and gain new skills, which will enable them to become more independent and enhance their individuality. During middle childhood, children enter the school years, where they are presented with a different setting than they are used to. This new setting creates new challenges and faces for children.[19] Upon the entrance of school, mental disorders that would normally not be noticed come to light. Many of these disorders include: autism, dyslexia, dyscalculia, and ADHD.[20]: 303–309  Special education, least restrictive environment, response to intervention and individualized education plans are all specialized plans to help children with disabilities.[20]: 310–311 

Middle childhood is the time when children begin to understand responsibility and are beginning to be shaped by their peers and parents. Chores and more responsible decisions come at this time, as do social comparison and social play.[20]: 338  During social play, children learn from and teach each other, often through observation.[21]

Late childhood

[edit]

Preadolescence is a stage of human development following early childhood and preceding adolescence. Preadolescence is commonly defined as ages 9–12, ending with the major onset of puberty, with markers such as menarche, spermarche, and the peak of height velocity occurring. These changes usually occur between ages 11 and 14. It may also be defined as the 2-year period before the major onset of puberty.[22] Preadolescence can bring its own challenges and anxieties. Preadolescent children have a different view of the world from younger children in many significant ways. Typically, theirs is a more realistic view of life than the intense, fantasy-oriented world of earliest childhood. Preadolescents have more mature, sensible, realistic thoughts and actions: 'the most "sensible" stage of development...the child is a much less emotional being now.'[23] Preadolescents may well view human relationships differently (e.g. they may notice the flawed, human side of authority figures). Alongside that, they may begin to develop a sense of self-identity, and to have increased feelings of independence: 'may feel an individual, no longer "just one of the family."'[24]

Developmental stages post-childhood

[edit]

Adolescence

[edit]

Adolescence is usually determined to be between the onset of puberty and legal adulthood: mostly corresponding to the teenage years (13–19). However, puberty usually begins before the teenage years (10—11 for girls and 11—12 for boys). Although biologically a child is a human being between the stages of birth and puberty,[1][2] adolescents are legally considered children, as they tend to lack adult rights and are still required to attend compulsory schooling in many cultures, though this varies. The onset of adolescence brings about various physical, psychological and behavioral changes. The end of adolescence and the beginning of adulthood varies by country and by function, and even within a single nation-state or culture there may be different ages at which an individual is considered to be mature enough to be entrusted by society with certain tasks.

History

[edit]
Playing Children, by Song dynasty Chinese artist Su Hanchen, c. 1150 AD.

During the European Renaissance, artistic depictions of children increased dramatically, which did not have much effect on the social attitude toward children, however.[25]

The French historian Philippe Ariès argued that during the 1600s, the concept of childhood began to emerge in Europe,[26] however other historians like Nicholas Orme have challenged this view and argued that childhood has been seen as a separate stage since at least the medieval period.[27] Adults saw children as separate beings, innocent and in need of protection and training by the adults around them. The English philosopher John Locke was particularly influential in defining this new attitude towards children, especially with regard to his theory of the tabula rasa, which considered the mind at birth to be a "blank slate". A corollary of this doctrine was that the mind of the child was born blank, and that it was the duty of the parents to imbue the child with correct notions. During the early period of capitalism, the rise of a large, commercial middle class, mainly in the Protestant countries of the Dutch Republic and England, brought about a new family ideology centred around the upbringing of children. Puritanism stressed the importance of individual salvation and concern for the spiritual welfare of children.[28]

The Age of Innocence c. 1785/8. Reynolds emphasized the natural grace of children in his paintings.

The modern notion of childhood with its own autonomy and goals began to emerge during the 18th-century Enlightenment and the Romantic period that followed it.[29][30] Jean Jacques Rousseau formulated the romantic attitude towards children in his famous 1762 novel Emile: or, On Education. Building on the ideas of John Locke and other 17th-century thinkers, Jean-Jaques Rousseau described childhood as a brief period of sanctuary before people encounter the perils and hardships of adulthood.[29] Sir Joshua Reynolds' extensive children portraiture demonstrated the new enlightened attitudes toward young children. His 1788 painting The Age of Innocence emphasizes the innocence and natural grace of the posing child and soon became a public favourite.[31]

The idea of childhood as a locus of divinity, purity, and innocence is further expounded upon in William Wordsworth's "Ode: Intimations of Immortality from Recollections of Early Childhood", the imagery of which he "fashioned from a complex mix of pastoral aesthetics, pantheistic views of divinity, and an idea of spiritual purity based on an Edenic notion of pastoral innocence infused with Neoplatonic notions of reincarnation".[30] This Romantic conception of childhood, historian Margaret Reeves suggests, has a longer history than generally recognized, with its roots traceable to similarly imaginative constructions of childhood circulating, for example, in the neo-platonic poetry of seventeenth-century metaphysical poet Henry Vaughan (e.g., "The Retreate", 1650; "Childe-hood", 1655). Such views contrasted with the stridently didactic, Calvinist views of infant depravity.[32]

With the onset of industrialisation in England in 1760, the divergence between high-minded romantic ideals of childhood and the reality of the growing magnitude of child exploitation in the workplace, became increasingly apparent. By the late 18th century, British children were specially employed in factories and mines and as chimney sweeps,[33] often working long hours in dangerous jobs for low pay.[34] As the century wore on, the contradiction between the conditions on the ground for poor children and the middle-class notion of childhood as a time of simplicity and innocence led to the first campaigns for the imposition of legal protection for children.

British reformers attacked child labor from the 1830s onward, bolstered by the horrific descriptions of London street life by Charles Dickens.[35] The campaign eventually led to the Factory Acts, which mitigated the exploitation of children at the workplace[33][36]

Modern concepts of childhood

[edit]

The modern attitude to children emerged by the late 19th century; the Victorian middle and upper classes emphasized the role of the family and the sanctity of the child – an attitude that has remained dominant in Western societies ever since.[37] The genre of children's literature took off, with a proliferation of humorous, child-oriented books attuned to the child's imagination. Lewis Carroll's fantasy Alice's Adventures in Wonderland, published in 1865 in England, was a landmark in the genre; regarded as the first "English masterpiece written for children", its publication opened the "First Golden Age" of children's literature.

The latter half of the 19th century saw the introduction of compulsory state schooling of children across Europe, which decisively removed children from the workplace into schools.[38][39]

The market economy of the 19th century enabled the concept of childhood as a time of fun, happiness, and imagination. Factory-made dolls and doll houses delighted the girls and organized sports and activities were played by the boys.[40] The Boy Scouts was founded by Sir Robert Baden-Powell in 1908,[41][42] which provided young boys with outdoor activities aiming at developing character, citizenship, and personal fitness qualities.[43]

In the 20th century, Philippe Ariès, a French historian specializing in medieval history, suggested that childhood was not a natural phenomenon, but a creation of society in his 1960 book Centuries of Childhood. In 1961 he published a study of paintings, gravestones, furniture, and school records, finding that before the 17th century, children were represented as mini-adults.

In 1966, the American philosopher George Boas published the book The Cult of Childhood. Since then, historians have increasingly researched childhood in past times.[44]

In 2006, Hugh Cunningham published the book Invention of Childhood, looking at British childhood from the year 1000, the Middle Ages, to what he refers to as the Post War Period of the 1950s, 1960s and 1970s.[45]

Childhood evolves and changes as lifestyles change and adult expectations alter. In the modern era, many adults believe that children should not have any worries or work, as life should be happy and trouble-free. Childhood is seen as a mixture of simplicity, innocence, happiness, fun, imagination, and wonder. It is thought of as a time of playing, learning, socializing, exploring, and worrying in a world without much adult interference.[29][30]

A "loss of innocence" is a common concept, and is often seen as an integral part of coming of age. It is usually thought of as an experience or period in a child's life that widens their awareness of evil, pain or the world around them. This theme is demonstrated in the novels To Kill a Mockingbird and Lord of the Flies. The fictional character Peter Pan was the embodiment of a childhood that never ends.[46][47]

Healthy childhoods

[edit]

Role of parents

[edit]

Children's health

[edit]

Children's health includes the physical, mental and social well-being of children. Maintaining children's health implies offering them healthy foods, insuring they get enough sleep and exercise, and protecting their safety.[48] Children in certain parts of the world often suffer from malnutrition, which is often associated with other conditions, such diarrhea, pneumonia and malaria.[49]

Child protection

[edit]

Child protection, according to UNICEF, refers to "preventing and responding to violence, exploitation and abuse against children – including commercial sexual exploitation, trafficking, child labour and harmful traditional practices, such as female genital mutilation/cutting and child marriage".[50] The Convention on the Rights of the Child protects the fundamental rights of children.

Play

[edit]

Play is essential to the cognitive, physical, social, and emotional well-being of children.[51] It offers children opportunities for physical (running, jumping, climbing, etc.), intellectual (social skills, community norms, ethics and general knowledge) and emotional development (empathy, compassion, and friendships). Unstructured play encourages creativity and imagination. Playing and interacting with other children, as well as some adults, provides opportunities for friendships, social interactions, conflicts and resolutions. However, adults tend to (often mistakenly) assume that virtually all children's social activities can be understood as "play" and, furthermore, that children's play activities do not involve much skill or effort.[52][53][54][55]

It is through play that children at a very early age engage and interact in the world around them. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles, sometimes in conjunction with other children or adult caregivers.[51] Undirected play allows children to learn how to work in groups, to share, to negotiate, to resolve conflicts, and to learn self-advocacy skills. However, when play is controlled by adults, children acquiesce to adult rules and concerns and lose some of the benefits play offers them. This is especially true in developing creativity, leadership, and group skills.[51]

Ralph Hedley, The Tournament, 1898. It depicts poorer boys playing outdoors in a rural part of the Northeast of England.

Play is considered to be very important to optimal child development that it has been recognized by the United Nations Commission on Human Rights as a right of every child.[11] Children who are being raised in a hurried and pressured style may limit the protective benefits they would gain from child-driven play.[51]

The initiation of play in a classroom setting allows teachers and students to interact through playfulness associated with a learning experience. Therefore, playfulness aids the interactions between adults and children in a learning environment. “Playful Structure” means to combine informal learning with formal learning to produce an effective learning experience for children at a young age.[56]

Even though play is considered to be the most important to optimal child development, the environment affects their play and therefore their development. Poor children confront widespread environmental inequities as they experience less social support, and their parents are less responsive and more authoritarian. Children from low income families are less likely to have access to books and computers which would enhance their development.[57]

Street culture

[edit]
Children in front of a movie theatre, Toronto, 1920s.

Children's street culture refers to the cumulative culture created by young children and is sometimes referred to as their secret world. It is most common in children between the ages of seven and twelve. It is strongest in urban working class industrial districts where children are traditionally free to play out in the streets for long periods without supervision. It is invented and largely sustained by children themselves with little adult interference.

Young children's street culture usually takes place on quiet backstreets and pavements, and along routes that venture out into local parks, playgrounds, scrub and wasteland, and to local shops. It often imposes imaginative status on certain sections of the urban realm (local buildings, kerbs, street objects, etc.). Children designate specific areas that serve as informal meeting and relaxation places (see: Sobel, 2001). An urban area that looks faceless or neglected to an adult may have deep 'spirit of place' meanings in to children. Since the advent of indoor distractions such as video games, and television, concerns have been expressed about the vitality – or even the survival – of children's street culture.

Geographies of childhood

[edit]

The geographies of childhood involves how (adult) society perceives the idea of childhood, the many ways adult attitudes and behaviors affect children's lives, including the environment which surrounds children and its implications.[58]

The geographies of childhood is similar in some respects to children's geographies which examines the places and spaces in which children live.[59]

Nature deficit disorder

[edit]

Nature Deficit Disorder, a term coined by Richard Louv in his 2005 book Last Child in the Woods, refers to the trend in the United States and Canada towards less time for outdoor play,[60][61] resulting in a wide range of behavioral problems.[62]

With increasing use of cellphones, computers, video games and television, children have more reasons to stay inside rather than outdoors exploring. “The average American child spends 44 hours a week with electronic media”.[63] Research in 2007 has drawn a correlation between the declining number of National Park visits in the U.S. and increasing consumption of electronic media by children.[64] The media has accelerated the trend for children's nature disconnection by deemphasizing views of nature, as in Disney films.[65]

Age of responsibility

[edit]

The age at which children are considered responsible for their society-bound actions (e. g. marriage, voting, etc.) has also changed over time,[66] and this is reflected in the way they are treated in courts of law. In Roman times, children were regarded as not culpable for crimes, a position later adopted by the Church. In the 19th century, children younger than seven years old were believed incapable of crime. Children from the age of seven forward were considered responsible for their actions. Therefore, they could face criminal charges, be sent to adult prison, and be punished like adults by whipping, branding or hanging. However, courts at the time would consider the offender's age when deliberating sentencing.[citation needed] Minimum employment age and marriage age also vary. The age limit of voluntary/involuntary military service is also disputed at the international level.[67]

Education

[edit]

Education, in the general sense, refers to the act or process of imparting or acquiring general knowledge, developing the powers of reasoning and judgment, and preparing intellectually for mature life.[68] Formal education most often takes place through schooling. A right to education has been recognized by some governments. At the global level, Article 13 of the United Nations' 1966 International Covenant on Economic, Social and Cultural Rights (ICESCR) recognizes the right of everyone to an education.[69] Education is compulsory in most places up to a certain age, but attendance at school may not be, with alternative options such as home-schooling or e-learning being recognized as valid forms of education in certain jurisdictions.

Children in some countries (especially in parts of Africa and Asia) are often kept out of school, or attend only for short periods. Data from UNICEF indicate that in 2011, 57 million children were out of school; and more than 20% of African children have never attended primary school or have left without completing primary education.[70] According to a UN report, warfare is preventing 28 million children worldwide from receiving an education, due to the risk of sexual violence and attacks in schools.[71] Other factors that keep children out of school include poverty, child labor, social attitudes, and long distances to school.[72][73]

Attitudes toward children

[edit]
Group of breaker boys in Pittston, Pennsylvania, 1911. Child labor was widespread until the early 20th century. In the 21st century, child labor rates are highest in Africa.

Social attitudes toward children differ around the world in various cultures and change over time. A 1988 study on European attitudes toward the centrality of children found that Italy was more child-centric and the Netherlands less child-centric, with other countries, such as Austria, Great Britain, Ireland and West Germany falling in between.[74]

In 2013, child marriage rates of female children under the age of 18 reached 75% in Niger, 68% in Central African Republic and Chad, 66% in Bangladesh, and 47% in India.[75] According to a 2019 UNICEF report on child marriage, 37% of females were married before the age of 18 in sub-Saharan Africa, followed by South Asia at 30%. Lower levels were found in Latin America and Caribbean (25%), the Middle East and North Africa (18%), and Eastern Europe and Central Asia (11%), while rates in Western Europe and North America were minimal.[76] Child marriage is more prevalent with girls, but also involves boys. A 2018 study in the journal Vulnerable Children and Youth Studies found that, worldwide, 4.5% of males are married before age 18, with the Central African Republic having the highest average rate at 27.9%.[77]

Fertility and number of children per woman

[edit]

Before contraception became widely available in the 20th century, women had little choice other than abstinence or having often many children. In fact, current population growth concerns have only become possible with drastically reduced child mortality and sustained fertility. In 2017 the global total fertility rate was estimated to be 2.37 children per woman,[78] adding about 80 million people to the world population per year. In order to measure the total number of children, scientists often prefer the completed cohort fertility at age 50 years (CCF50).[78] Although the number of children is also influenced by cultural norms, religion, peer pressure and other social factors, the CCF50 appears to be most heavily dependent on the educational level of women, ranging from 5–8 children in women without education to less than 2 in women with 12 or more years of education.[78]

Issues

[edit]

Emergencies and conflicts

[edit]

Emergencies and conflicts pose detrimental risks to the health, safety, and well-being of children. There are many different kinds of conflicts and emergencies, e.g. wars and natural disasters. As of 2010 approximately 13 million children are displaced by armed conflicts and violence around the world.[79] Where violent conflicts are the norm, the lives of young children are significantly disrupted and their families have great difficulty in offering the sensitive and consistent care that young children need for their healthy development.[79] Studies on the effect of emergencies and conflict on the physical and mental health of children between birth and 8 years old show that where the disaster is natural, the rate of PTSD occurs in anywhere from 3 to 87 percent of affected children.[80] However, rates of PTSD for children living in chronic conflict conditions varies from 15 to 50 percent.[81][82]

Child protection

[edit]
 

Child protection (also called child welfare) is the safeguarding of children from violence, exploitation, abuse, abandonment, and neglect.[83][84][85][86] It involves identifying signs of potential harm. This includes responding to allegations or suspicions of abuse, providing support and services to protect children, and holding those who have harmed them accountable.[87]

The primary goal of child protection is to ensure that all children are safe and free from harm or danger.[86][88] Child protection also works to prevent future harm by creating policies and systems that identify and respond to risks before they lead to harm.[89]

In order to achieve these goals, research suggests that child protection services should be provided in a holistic way.[90][91][92] This means taking into account the social, economic, cultural, psychological, and environmental factors that can contribute to the risk of harm for individual children and their families. Collaboration across sectors and disciplines to create a comprehensive system of support and safety for children is required.[93][94]

It is the responsibility of individuals, organizations, and governments to ensure that children are protected from harm and their rights are respected.[95] This includes providing a safe environment for children to grow and develop, protecting them from physical, emotional and sexual abuse, and ensuring they have access to education, healthcare, and resources to fulfill their basic needs.[96]

Child protection systems are a set of services, usually government-run, designed to protect children and young people who are underage and to encourage family stability. UNICEF defines[97] a 'child protection system' as:

"The set of laws, policies, regulations and services needed across all social sectors – especially social welfare, education, health, security and justice – to support prevention and response to protection-related risks. These systems are part of social protection, and extend beyond it. At the level of prevention, their aim includes supporting and strengthening families to reduce social exclusion, and to lower the risk of separation, violence and exploitation. Responsibilities are often spread across government agencies, with services delivered by local authorities, non-State providers, and community groups, making coordination between sectors and levels, including routine referral systems etc.., a necessary component of effective child protection systems."

— United Nations Economic and Social Council (2008), UNICEF Child Protection Strategy, E/ICEF/2008/5/Rev.1, par. 12–13.

Under Article 19 of the UN Convention on the Rights of the Child, a 'child protection system' provides for the protection of children in and out of the home. One of the ways this can be enabled is through the provision of quality education, the fourth of the United Nations Sustainable Development Goals, in addition to other child protection systems. Some literature argues that child protection begins at conception; even how the conception took place can affect the child's development.[98]

Child abuse and child labor

[edit]

Protection of children from abuse is considered an important contemporary goal. This includes protecting children from exploitation such as child labor, child trafficking and child selling, child sexual abuse, including child prostitution and child pornography, military use of children, and child laundering in illegal adoptions. There exist several international instruments for these purposes, such as:

  • Worst Forms of Child Labour Convention
  • Minimum Age Convention, 1973
  • Optional Protocol on the Sale of Children, Child Prostitution and Child Pornography
  • Council of Europe Convention on the Protection of Children against Sexual Exploitation and Sexual Abuse
  • Optional Protocol on the Involvement of Children in Armed Conflict
  • Hague Adoption Convention

Climate change

[edit]

Children are more vulnerable to the effects of climate change than adults. The World Health Organization estimated that 88% of the existing global burden of disease caused by climate change affects children under five years of age.[99] A Lancet review on health and climate change lists children as the worst-affected category by climate change.[100] Children under 14 are 44 percent more likely to die from environmental factors,[101] and those in urban areas are disproportionately impacted by lower air quality and overcrowding.[102]

Children are physically more vulnerable to climate change in all its forms.[103] Climate change affects the physical health of children and their well-being. Prevailing inequalities, between and within countries, determine how climate change impacts children.[104] Children often have no voice in terms of global responses to climate change.[103]

People living in low-income countries experience a higher burden of disease and are less capable of coping with climate change-related threats.[105] Nearly every child in the world is at risk from climate change and pollution, while almost half are at extreme risk.[106]

Health

[edit]

Child mortality

[edit]
World infant mortality rates in 2012.[107]

During the early 17th century in England, about two-thirds of all children died before the age of four.[108] During the Industrial Revolution, the life expectancy of children increased dramatically.[109] This has continued in England, and in the 21st century child mortality rates have fallen across the world. About 12.6 million under-five infants died worldwide in 1990, which declined to 6.6 million in 2012. The infant mortality rate dropped from 90 deaths per 1,000 live births in 1990, to 48 in 2012. The highest average infant mortality rates are in sub-Saharan Africa, at 98 deaths per 1,000 live births – over double the world's average.[107]

Dental braces

Dental braces (also known as orthodontic braces, or simply braces) are devices used in orthodontics that align and straighten teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws.

Process

[edit]

The application of braces moves the teeth as a result of force and pressure on the teeth. Traditionally, four basic elements are used: brackets, bonding material, arch wire, and ligature elastic (also called an "O-ring"). The teeth move when the arch wire puts pressure on the brackets and teeth. Sometimes springs or rubber bands are used to put more force in a specific direction.[1]

Braces apply constant pressure which, over time, moves teeth into the desired positions. The process loosens the tooth after which new bone grows to support the tooth in its new position. This is called bone remodelling. Bone remodelling is a biomechanical process responsible for making bones stronger in response to sustained load-bearing activity and weaker in the absence of carrying a load. Bones are made of cells called osteoclasts and osteoblasts. Two different kinds of bone resorption are possible: direct resorption, which starts from the lining cells of the alveolar bone, and indirect or retrograde resorption, which occurs when the periodontal ligament has been subjected to an excessive amount and duration of compressive stress.[2] Another important factor associated with tooth movement is bone deposition. Bone deposition occurs in the distracted periodontal ligament. Without bone deposition, the tooth will loosen, and voids will occur distal to the direction of tooth movement.[3]

Types

[edit]
"Clear" braces
Upper and Lower Jaw Functional Expanders
  • Traditional metal wired braces (also known as "train track braces") are stainless-steel and are sometimes used in combination with titanium. Traditional metal braces are the most common type of braces.[4] These braces have a metal bracket with elastic ties (also known as rubber bands) holding the wire onto the metal brackets. The second-most common type of braces is self-ligating braces, which have a built-in system to secure the archwire to the brackets and do not require elastic ties. Instead, the wire goes through the bracket. Often with this type of braces, treatment time is reduced, there is less pain on the teeth, and fewer adjustments are required than with traditional braces.
  • Gold-plated stainless steel braces are often employed for patients allergic to nickel (a basic and important component of stainless steel), but may also be chosen for aesthetic reasons.
  • Lingual braces are a cosmetic alternative in which custom-made braces are bonded to the back of the teeth making them externally invisible.
  • Titanium braces resemble stainless-steel braces but are lighter and just as strong. People with allergies to nickel in steel often choose titanium braces, but they are more expensive than stainless steel braces.
  • Customized orthodontic treatment systems combine high technology including 3-D imaging, treatment planning software and a robot to custom bend the wire. Customized systems such as this offer faster treatment times and more efficient results.[5]
  • Progressive, clear removable aligners may be used to gradually move teeth into their final positions. Aligners are generally not used for complex orthodontic cases, such as when extractions, jaw surgery, or palate expansion are necessary.[medical citation needed][6]

Fitting procedure

[edit]
A patient's teeth are prepared for the application of braces.

Orthodontic services may be provided by any licensed dentist trained in orthodontics. In North America, most orthodontic treatment is done by orthodontists, who are dentists in the diagnosis and treatment of malocclusions—malalignments of the teeth, jaws, or both. A dentist must complete 2–3 years of additional post-doctoral training to earn a specialty certificate in orthodontics. There are many general practitioners who also provide orthodontic services.

The first step is to determine whether braces are suitable for the patient. The doctor consults with the patient and inspects the teeth visually. If braces are appropriate, a records appointment is set up where X-rays, moulds, and impressions are made. These records are analyzed to determine the problems and the proper course of action. The use of digital models is rapidly increasing in the orthodontic industry. Digital treatment starts with the creation of a three-dimensional digital model of the patient's arches. This model is produced by laser-scanning plaster models created using dental impressions. Computer-automated treatment simulation has the ability to automatically separate the gums and teeth from one another and can handle malocclusions well; this software enables clinicians to ensure, in a virtual setting, that the selected treatment will produce the optimal outcome, with minimal user input.[medical citation needed]

Typical treatment times vary from six months to two and a half years depending on the complexity and types of problems. Orthognathic surgery may be required in extreme cases. About 2 weeks before the braces are applied, orthodontic spacers may be required to spread apart back teeth in order to create enough space for the bands.

Teeth to be braced will have an adhesive applied to help the cement bond to the surface of the tooth. In most cases, the teeth will be banded and then brackets will be added. A bracket will be applied with dental cement, and then cured with light until hardened. This process usually takes a few seconds per tooth. If required, orthodontic spacers may be inserted between the molars to make room for molar bands to be placed at a later date. Molar bands are required to ensure brackets will stick. Bands are also utilized when dental fillings or other dental works make securing a bracket to a tooth infeasible. Orthodontic tubes (stainless steel tubes that allow wires to pass through them), also known as molar tubes, are directly bonded to molar teeth either by a chemical curing or a light curing adhesive. Usually, molar tubes are directly welded to bands, which is a metal ring that fits onto the molar tooth. Directly bonded molar tubes are associated with a higher failure rate when compared to molar bands cemented with glass ionomer cement. Failure of orthodontic brackets, bonded tubes or bands will increase the overall treatment time for the patient. There is evidence suggesting that there is less enamel decalcification associated with molar bands cemented with glass ionomer cement compared with orthodontic tubes directly cemented to molars using a light cured adhesive. Further evidence is needed to withdraw a more robust conclusion due to limited data.[7]

An archwire will be threaded between the brackets and affixed with elastic or metal ligatures. Ligatures are available in a wide variety of colours, and the patient can choose which colour they like. Arch wires are bent, shaped, and tightened frequently to achieve the desired results.

Dental braces, with a transparent power chain, removed after completion of treatment.

Modern orthodontics makes frequent use of nickel-titanium archwires and temperature-sensitive materials. When cold, the archwire is limp and flexible, easily threaded between brackets of any configuration. Once heated to body temperature, the arch wire will stiffen and seek to retain its shape, creating constant light force on the teeth.

Brackets with hooks can be placed, or hooks can be created and affixed to the arch wire to affix rubber bands. The placement and configuration of the rubber bands will depend on the course of treatment and the individual patient. Rubber bands are made in different diameters, colours, sizes, and strengths. They are also typically available in two versions: Coloured or clear/opaque.

The fitting process can vary between different types of braces, though there are similarities such as the initial steps of moulding the teeth before application. For example, with clear braces, impressions of a patient's teeth are evaluated to create a series of trays, which fit to the patient's mouth almost like a protective mouthpiece. With some forms of braces, the brackets are placed in a special form that is customized to the patient's mouth, drastically reducing the application time.

In many cases, there is insufficient space in the mouth for all the teeth to fit properly. There are two main procedures to make room in these cases. One is extraction: teeth are removed to create more space. The second is expansion, in which the palate or arch is made larger by using a palatal expander. Expanders can be used with both children and adults. Since the bones of adults are already fused, expanding the palate is not possible without surgery to separate them. An expander can be used on an adult without surgery but would be used to expand the dental arch, and not the palate.

Sometimes children and teenage patients, and occasionally adults, are required to wear a headgear appliance as part of the primary treatment phase to keep certain teeth from moving (for more detail on headgear and facemask appliances see Orthodontic headgear). When braces put pressure on one's teeth, the periodontal membrane stretches on one side and is compressed on the other. This movement needs to be done slowly or otherwise, the patient risks losing their teeth. This is why braces are worn as long as they are and adjustments are only made every so often.

Braces are typically adjusted every three to six weeks. This helps shift the teeth into the correct position. When they get adjusted, the orthodontist removes the coloured or metal ligatures keeping the arch wire in place. The arch wire is then removed and may be replaced or modified. When the archwire has been placed back into the mouth, the patient may choose a colour for the new elastic ligatures, which are then affixed to the metal brackets. The adjusting process may cause some discomfort to the patient, which is normal.

Post-treatment

[edit]

Patients may need post-orthodontic surgery, such as a fiberotomy or alternatively a gum lift, to prepare their teeth for retainer use and improve the gumline contours after the braces come off. After braces treatment, patients can use a transparent plate to keep the teeth in alignment for a certain period of time. After treatment, patients usually use transparent plates for 6 months. In patients with long and difficult treatment, a fixative wire is attached to the back of the teeth to prevent the teeth from returning to their original state.[8]

Retainers

[edit]
Hawley retainers are the most common type of retainers. This picture shows retainers for the top (right) and bottom (left) of the mouth.

In order to prevent the teeth from moving back to their original position, retainers are worn once the treatment is complete. Retainers help in maintaining and stabilizing the position of teeth long enough to permit the reorganization of the supporting structures after the active phase of orthodontic therapy. If the patient does not wear the retainer appropriately and/or for the right amount of time, the teeth may move towards their previous position. For regular braces, Hawley retainers are used. They are made of metal hooks that surround the teeth and are enclosed by an acrylic plate shaped to fit the patient's palate. For Clear Removable braces, an Essix retainer is used. This is similar to the original aligner; it is a clear plastic tray that is firmly fitted to the teeth and stays in place without a plate fitted to the palate. There is also a bonded retainer where a wire is permanently bonded to the lingual side of the teeth, usually the lower teeth only.

Headgear

[edit]

Headgear needs to be worn between 12 and 22 hours each day to be effective in correcting the overbite, typically for 12 to 18 months depending on the severity of the overbite, how much it is worn and what growth stage the patient is in. Typically the prescribed daily wear time will be between 14 and 16 hours a day and is frequently used as a post-primary treatment phase to maintain the position of the jaw and arch. Headgear can be used during the night while the patient sleeps.[9][better source needed]

Orthodontic headgear usually consists of three major components:

Full orthodontic headgear with head cap, fitting straps, facebow and elastics
  1. Facebow: the facebow (or J-Hooks) is fitted with a metal arch onto headgear tubes attached to the rear upper and lower molars. This facebow then extends out of the mouth and around the patient's face. J-Hooks are different in that they hook into the patient's mouth and attach directly to the brace (see photo for an example of J-Hooks).
  2. Head cap: the head cap typically consists of one or a number of straps fitting around the patient's head. This is attached with elastic bands or springs to the facebow. Additional straps and attachments are used to ensure comfort and safety (see photo).
  3. Attachment: typically consisting of rubber bands, elastics, or springs—joins the facebow or J-Hooks and the head cap together, providing the force to move the upper teeth, jaw backwards.

The headgear application is one of the most useful appliances available to the orthodontist when looking to correct a Class II malocclusion. See more details in the section Orthodontic headgear.

Pre-finisher

[edit]

The pre-finisher is moulded to the patient's teeth by use of extreme pressure on the appliance by the person's jaw. The product is then worn a certain amount of time with the user applying force to the appliance in their mouth for 10 to 15 seconds at a time. The goal of the process is to increase the exercise time in applying the force to the appliance. If a person's teeth are not ready for a proper retainer the orthodontist may prescribe the use of a preformed finishing appliance such as the pre-finisher. This appliance fixes gaps between the teeth, small spaces between the upper and lower jaw, and other minor problems.

Complications and risks

[edit]

A group of dental researchers, Fatma Boke, Cagri Gazioglu, Selvi Akkaya, and Murat Akkaya, conducted a study titled "Relationship between orthodontic treatment and gingival health." The results indicated that some orthodontist treatments result in gingivitis, also known as gum disease. The researchers concluded that functional appliances used to harness natural forces (such as improving the alignment of bites) do not usually have major effects on the gum after treatment.[10] However, fixed appliances such as braces, which most people get, can result in visible plaque, visible inflammation, and gum recession in a majority of the patients. The formation of plaques around the teeth of patients with braces is almost inevitable regardless of plaque control and can result in mild gingivitis. But if someone with braces does not clean their teeth carefully, plaques will form, leading to more severe gingivitis and gum recession.

Experiencing some pain following fitting and activation of fixed orthodontic braces is very common and several methods have been suggested to tackle this.[11][12] Pain associated with orthodontic treatment increases in proportion to the amount of force that is applied to the teeth. When a force is applied to a tooth via a brace, there is a reduction in the blood supply to the fibres that attach the tooth to the surrounding bone. This reduction in blood supply results in inflammation and the release of several chemical factors, which stimulate the pain response. Orthodontic pain can be managed using pharmacological interventions, which involve the use of analgesics applied locally or systemically. These analgesics are divided into four main categories, including opioids, non-steroidal anti-inflammatory drugs (NSAIDs), paracetamol and local anesthesia. The first three of these analgesics are commonly taken systemically to reduce orthodontic pain.[13]

A Cochrane Review in 2017 evaluated the pharmacological interventions for pain relief during orthodontic treatment. The study concluded that there was moderate-quality evidence that analgesics reduce the pain associated with orthodontic treatment. However, due to a lack of evidence, it was unclear whether systemic NSAIDs were more effective than paracetamol, and whether topical NSAIDs were more effective than local anaesthesia in the reduction of pain associated with orthodontic treatment. More high-quality research is required to investigate these particular comparisons.[13]

The dental displacement obtained with the orthodontic appliance determines in most cases some degree of root resorption. Only in a few cases is this side effect large enough to be considered real clinical damage to the tooth. In rare cases, the teeth may fall out or have to be extracted due to root resorption.[14][15]

History

[edit]

Ancient

[edit]
Old Braces at a museum in Jbeil, Lebanon

According to scholars and historians, braces date back to ancient times. Around 400–300 BC, Hippocrates and Aristotle contemplated ways to straighten teeth and fix various dental conditions. Archaeologists have discovered numerous mummified ancient individuals with what appear to be metal bands wrapped around their teeth. Catgut, a type of cord made from the natural fibres of an animal's intestines, performed a similar role to today's orthodontic wire in closing gaps in the teeth and mouth.[16]

The Etruscans buried their dead with dental appliances in place to maintain space and prevent the collapse of the teeth during the afterlife. A Roman tomb was found with a number of teeth bound with gold wire documented as a ligature wire, a small elastic wire that is used to affix the arch wire to the bracket. Even Cleopatra wore a pair. Roman philosopher and physician Aulus Cornelius Celsus first recorded the treatment of teeth by finger pressure. Unfortunately, due to a lack of evidence, poor preservation of bodies, and primitive technology, little research was carried out on dental braces until around the 17th century, although dentistry was making great advancements as a profession by then.[citation needed]

18th century

[edit]
Portrait of Fauchard from his 1728 edition of "The Surgical Dentist".

Orthodontics truly began developing in the 18th and 19th centuries. In 1669, French dentist Pierre Fauchard, who is often credited with inventing modern orthodontics, published a book entitled "The Surgeon Dentist" on methods of straightening teeth. Fauchard, in his practice, used a device called a "Bandeau", a horseshoe-shaped piece of iron that helped expand the palate. In 1754, another French dentist, Louis Bourdet, dentist to the King of France, followed Fauchard's book with The Dentist's Art, which also dedicated a chapter to tooth alignment and application. He perfected the "Bandeau" and was the first dentist on record to recommend extraction of the premolar teeth to alleviate crowding and improve jaw growth.

19th century

[edit]

Although teeth and palate straightening and/or pulling were used to improve the alignment of remaining teeth and had been practised since early times, orthodontics, as a science of its own, did not really exist until the mid-19th century. Several important dentists helped to advance dental braces with specific instruments and tools that allowed braces to be improved.

In 1819, Christophe François Delabarre introduced the wire crib, which marked the birth of contemporary orthodontics, and gum elastics were first employed by Maynard in 1843. Tucker was the first to cut rubber bands from rubber tubing in 1850. Dentist, writer, artist, and sculptor Norman William Kingsley in 1858 wrote the first article on orthodontics and in 1880, his book, Treatise on Oral Deformities, was published. A dentist named John Nutting Farrar is credited for writing two volumes entitled, A Treatise on the Irregularities of the Teeth and Their Corrections and was the first to suggest the use of mild force at timed intervals to move teeth.

20th century

[edit]

In the early 20th century, Edward Angle devised the first simple classification system for malocclusions, such as Class I, Class II, and so on. His classification system is still used today as a way for dentists to describe how crooked teeth are, what way teeth are pointing, and how teeth fit together. Angle contributed greatly to the design of orthodontic and dental appliances, making many simplifications. He founded the first school and college of orthodontics, organized the American Society of Orthodontia in 1901 which became the American Association of Orthodontists (AAO) in the 1930s, and founded the first orthodontic journal in 1907. Other innovations in orthodontics in the late 19th and early 20th centuries included the first textbook on orthodontics for children, published by J.J. Guilford in 1889, and the use of rubber elastics, pioneered by Calvin S. Case, along with Henry Albert Baker.

Today, space age wires (also known as dental arch wires) are used to tighten braces. In 1959, the Naval Ordnance Laboratory created an alloy of nickel and titanium called Nitinol. NASA further studied the material's physical properties.[17] In 1979, Dr. George Andreasen developed a new method of fixing braces with the use of the Nitinol wires based on their superelasticity. Andreasen used the wire on some patients and later found out that he could use it for the entire treatment. Andreasen then began using the nitinol wires for all his treatments and as a result, dental doctor visits were reduced, the cost of dental treatment was reduced, and patients reported less discomfort.
