This type of surgery is used to correct jaws and teeth that don't meet correctly. It is also used for patients who are unable to chew or speak properly or for those patients who wish to improve their appearance.
Orthognathic surgery is also used for cases of severe facial abnormalities due to genetic deformities. Orthognathic surgery often addresses a combination of these concerns and is often required when orthodontics (braces) alone cannot correct jaw or functional problems. Many jaw surgery cases present after inadviseable and unsuccessful attempts to finish cases where braces alone have failed. However, the situation is usually quickly resolved with the appropriate evaluation and treatment.
