What is jaw corrective surgery?

Otherwise referred to as Orthognathic Surgery.  It is primarily used to correct a poor bite and also to improve the lower facial appearance by surgically aligning the jaws to balance out the lower part of the face.

Is there any preparation required?

YES. Most patients who undergo orthognathic surgery require orthodontics (i.e. braces) to align the teeth for 12 months before the jaw surgery is undertaken and then a further 6-12 months of braces after the jaw surgery to fine tune the bite. Moulds are taken of the teeth and x-rays are needed to plan the exact movement of the jaws so that the patient ends up with the best functional and aesthetic result.

What does the jaw surgery involve?

All the surgery is undertaken through the mouth so there are no scars on the face. Controlled fractures of the jaws are performed so that they can be moved into the planned position. Once in the new position, the jaws are fixed there with miniature titanium plates and screws so that the bones can heal in their new position. While hospital stay can range from 1-4 days, recovery takes about 3-4 weeks depending on the complexity of the surgery. If you have a jaw deformity that you would like fixed, make an appointment to discuss this with the surgeon.
