ORTHOGNATHIC SURGERY


Some patients are born with smaller or larger than normal jaw bones which can interfere with their oral function and also their appearance. The oral and maxillofacial surgeon is in an ideal position to treat these being trained in both dentistry and medicine. Moving the position of the jaw bones are unique to our speciality due to our understanding of the facial structures including the dentition.

Depending upon the diagnosis, an oral and maxillofacial surgeon can choose to move the mandible(lower jaw), the maxilla(upper jaw) or both.

The usual treatment regime involves a duration of orthodontics in the first instance to straighten and align the teeth followed by jaw surgery and then a shorter period of orthodontics to help refine the dental occlusion(bite). Treatment time is typically between 18 months to 2 years.
