Orthodontia, also known as orthodontics and dentofacial orthopedics, was the first specialty created in the field of dentistry. An orthodontist is a specialist who has undergone special training in a dental school or college after he/she has graduated in dentistry. It was established by the efforts of pioneering orthodontists such as Edward Angle and Norman William Kingsley. The specialty deals primarily with the diagnosis, prevention and correction of malpositioned teeth and the jaws.
