Jaw Surgery (orthognathic surgery) may be required or requested
when a person’s upper and lower jaws grow at different speeds.
At the speed that your jaws grow (very slowly), an under-bite or
over-bite can be noticeable early on or it could take many years
to develop. Fundamentally, this procedure is available and practiced
on those whose jaws do not fit together correctly.
With orthognathic surgery, this problem can be reversed. Correcting
misaligned jaws can solve a broad range of problems for a patient,
including speaking, chewing, breathing, and swallowing.
Before surgery, the teeth are properly aligned through orthodontic
therapy (braces). Orthodontics corrects the crowding of teeth and
abnormal tooth angulations and rotations. Once the teeth are properly
aligned, orthognathic surgery is used to fix the misaligned jaws.
