An oral and maxillofacial surgeon will perform your orthognathic surgery, and the surgery will take place in a hospital. Orthognathic surgery can take several hours depending on each individual case. Once the surgery is complete, you will have about a two-week rest period. Since orthognathic surgery is a major treatment, we recommend that you schedule some time away from work and school during the healing process. After your jaw has healed, your orthodontist will once again “fine-tune” your bite. After surgery, you will have to wear braces, and most braces are removed within six to 12 months following surgery. After your braces are removed, you will wear a retainer to help maintain your new smile.
