ORTHODONTICS PROFESSION

Orthodontics is a specialty of dentistry that is concerned with the study and treatment of malocclusions (improper bites), which may be a result of tooth irregularity, disproportionate jaw relationships, or both. The word comes from the Greek words ortho meaning straight and odons meaning tooth.
Orthodontic treatment can focus on dental displacement only, or can deal with the control and modification of facial growth. In the latter case it is better defined as "dentofacial orthopedics". Orthodontic treatment can be carried out for purely aesthetic reasons—improving the general appearance of patients' teeth and face for cosmetic reasons—but treatment is often prescribed for practical reasons, providing the patient with a functionally improved bite (occlusion).
ORTHODONTICS METHODS
If the main goal of the treatment is the dental displacement, most commonly a fixed multibracket therapy is used. In this case orthodontic wires are inserted into dental braces, which can be made from stainless steel or a more esthetic ceramic material.
Also removable appliances, or "plates", headgear, expansion appliances, and many other devices can be used to move teeth. Functional and orthopaedics appliances are used in growing patients (age 5 to 13) with the aim to modify the jaw dimensions and relationship if these are altered. (See Prognathism.) This therapy is frequently followed by a fixed multibracket therapy to align the teeth and refine the occlusion.
After a course of active orthodontic treatment, patients will often wear retainers, which will maintain the teeth in their improved position while the surrounding bone reforms around them. The retainers are generally worn full-time for a short period, perhaps 6 months to a year, and then worn periodically (typically nightly during sleep) for as long as the orthodontist recommends. It is possible for the teeth to stay aligned without regular retainer wear. However, there are many reasons teeth will crowd as a person ages; thus there is no guarantee that teeth, orthodontically treated or otherwise, will stay aligned without retention. For this reason, many orthodontists recommend periodic retainer wear for many years (or indefinitely) after orthodontic treatment.Appropriately trained doctors align the teeth with respect to the surrounding soft tissues, with or without movement of the underlying bones, which can be moved either through growth modification in children or jaw surgery (orthognathic surgery) in adults.
Several appliances are utilized for growth modification; including functional appliances, Headgear and Facemasks.
These "orthopedic appliances" may influence the development of an adolescent's profile and give an improved aesthetic and functional result.
CONDITIONS
The most common condition that the methods of orthodontics are used for is correcting anteroposterior discrepancies. Another common situation leading to orthodontic treatment is crowding of the teeth.
1. Anteroposterior discrepancies:
Anteroposterior discrepancies are deviations between the teeth of the upper and lower jaw in the anteroposterior direction. For instance, the top teeth can be too far forward relative to the lower teeth ("increased overjet".) The headgear is attached to the braces via metal hooks or a facebow and is anchored from the back of the head or neck with straps or a head-cap. Elastic bands are typically then used to apply pressure to the bow or hooks. Its purpose is to slow-down or stop the upper jaw from growing, hence preventing or correcting an overjet. For more details and photographs, see Headgear - Orthodontic.
2. Crowding of teeth:
Another common situation leading to orthodontic treatment is crowding of the teeth. In this situation, there is insufficient room for the normal complement of adult teeth, which can sometimes motivate teeth being extracted in order to make enough room for the remaining teeth
DIAGNOSIS/TREATMENT PLANNING:In diagnosis and treatment planning, the orthodontist must (1) recognize the various characteristics of malocclusion and dentofacial deformity; (2) define the nature of the problem, including the etiology if possible; and (3) design a treatment strategy based on the specific needs and desires of the individual. (4) present the treatment strategy to the patient in such a way that the patient fully understands the ramifications of his/her decision.
OTHORDONTIC EDUCATION:
Various countries have their own systems for training and registering specialist orthodontists; generally a period of full-time post-graduate study is required for a dentist to qualify as an orthodontist. The orthodontic specialty is the earliest dental specialty.

EU - COUNTRIES:
In the United Kingdom, this training period lasts three years, after completion of a membership from a Royal College. A further two years is then completed to train to consultant level, after which a fellowship examination from the Royal College is sat. In other parts of Europe, a similar pattern is followed. It is always worth contacting the professional body responsible for registering orthodontists to ensure that the orthodontist you wish to consult is a recognized specialist.

UNITED STATES
A number of medical and dental schools in the United States offer advanced education in the specialty of Orthodontics to dentists seeking postgraduate education. The courses range from two to three years of full-time classes and clinical work in the clinical and theoretical aspects of orthodontics. Generally, admission is based on an application process followed by an extensive interviewing process by the institution, in order to select the best candidate. Candidates usually have to contact the individual school directly for the application process. A list of orthodontic schools can be obtained from the American Association of Orthodontists[1].
In addition to American Dental Association recognized specialty programs, there are other non-specialty continuing education programs. Two of the most prominent are the International Association for Orthodontics [2] and the United States Dental Institute [3]. These organizations provide very advanced continuing education to both general dentists and pedodontists (child specialists). These programs are taught by orthodontists, pedodontists, and experienced general dentists enabling your family dentist or pedodontist to provide quality orthodontic care. Some of these more experienced dentists can provide care for even the most complex of cases while others may choose to treat only simple cases and refer more complex treatment to orthodontists.
