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.

Orthognathic surgery is generally performed by your Oral and Maxillofacial Surgeon to correct malocclusion (bad bite) in cases where routine orthodontic treatment has not or will not be effective.  Orthognathic surgeries include the reconstruction of the mandible or maxilla, mandibular ramus, maxilla osteotomy, and mandibular osteotomy.

When the orthodontist or dentist 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. Your Oral & Maxillofacial Surgeon, your orthodontist and your general dentist will work together and consider how the corrective surgery will impact both proper jaw function and the aesthetic appearance of the entire face.
