Orthognathic surgery refers to the surgical correction needed to fix substantial abnormalities of the maxilla (upper jaw), the mandible (lower jaw), or both. The abnormality may be a birth defect, a growth defect, or the result of traumatic injuries to the jaw area.

When the orthodontist identifies a patient as a candidate for orthognathic surgery, a complete photographic analysis is initially undertaken. This includes panoramic x-rays, cephalometric x-rays, models, impressions, and radiographs. The orthodontist will then work with an oral & maxillofacial surgeon to consider how the corrective surgery will impact both proper jaw function and the aesthetic appearance of the entire face.

What does orthognathic surgery involve?

Generally, orthodontic braces are necessary to align the arches and straighten the teeth prior and following to the surgery.

During maxillary surgery, the upper jaw is moved and may be secured in position using tiny plates, wires, rubber bands and screws. Surgery on the mandible is performed using bone grafts to align the lower jaw into the correct position. Orthognathic surgery generally requires a general anesthesia and a good deal of aftercare. Pain medication will be prescribed as necessary, and you’ll be given post treatment advice for your recovery. You may also be provided with a modified diet (if required).

Throughout the process, the orthodontist will be in constant communication with your oral & maxillofacial surgeon to ensure the best possible treatment outcome.
