Orthognatic Surgery


Orthognathic surgery is surgery aimed to correction of functional and aesthetic of several dentofacial deformity through combination of orthodontic,surgical and possibly restorative dentistry.

To correct bite fit or jaw closure issues, such as when the molars touch but the front teeth don’t touch (open bite).

To correct facial imbalance (asymmetry), such as small chins, underbites, overbites and crossbites.

To improve the ability of the lips to fully close comfortably.

To relieve pain caused by temporomandibular joint (TMJ) disorder and other jaw problems.

To repair facial injury or birth defects.

To provide relief for obstructive sleep apnea.


In most cases, an orthodontist places braces on your teeth before surgery. Braces are usually on for 12 to18 months before surgery to level and align your teeth in preparation for surgery.

Your orthodontist and oral and maxillofacial surgeon work together to develop your treatment plan. X-rays,3dimensional CT,Computer Guided Treatment, pictures and models of your teeth are part of the planning for your jaw surgery. Occasionally, the difference in the way teeth fit together will require either reshaping of the teeth, covering the teeth with crowns or both to complete correction.

Surgery will be performed inside your mouth, so no facial scars show on your chin, jaw or around the mouth. However, sometimes small incisions may be required outside your mouth.

Your surgeon makes cuts in the jawbones and moves them into the correct position. Once your jaw movement is completed, tiny bone plates, screws, wires and rubber bands may be used to secure the bones into their new position. These screws — which are smaller than a bracket used for braces — become integrated into the bone structure over time.

In some cases, extra bone may be added to the jaw. Your surgeon transfers the bone from your hip, leg or rib and secures it with plates and screws. In other cases, bone may be reshaped to provide a better fit.

Jaw surgery may be performed on the upper jaw, lower jaw, chin or any combination of these.
