Orthodontics is a dentistry specialty that addresses the diagnosis, prevention, and correction of mal-positioned teeth and jaws, and misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics.
Treatment may require several months to a few years, and entails using dental braces and other appliances to gradually adjust tooth position and jaw alignment. In cases where the malocclusion is severe, jaw surgery may be incorporated in the treatment plan. Treatment usually begins before a person reaches adulthood, insofar as pre-adult bones may be adjusted more easily before adulthood.
Orthodontic therapy may include using fixed or removable appliances. Most orthodontic therapy is delivered using appliances that are fixed in place, for example, with braces that are adhesively bonded to the teeth. Fixed appliances may provide greater mechanical control of the teeth; optimal treatment outcome is improved by using fixed appliances.
Fixed appliances may be used, for example, to rotate teeth if that do not fit the arch shape of the other teeth in the mouth, to adjust multiple teeth to different places, to change tooth angle of teeth, or to change the position of a tooth's root. This treatment course is not preferred where a patient has poor oral hygiene, (as decalcification, tooth decay or other complications may result. If a patient is unmotivated (insofar as treatment takes several months and requires commitment to oral hygiene), or if malocclusions are mild.
Biology of tooth movement and how advances in gene therapy and molecular biology technology may shape the future of orthodontic treatment is an interesting area.
UNTIL THE MID - 1970'S, BRACES WERE MADE BY WRAPPING METAL AROUND EACH TOOTH. WITH ADVANCEMENTS IN ADHESIVES IT BECAME POSSIBLE TO INSTEAD BOND METAL BRACKETS TO THE TEETH....Read More
