After the first portion of orthodontic work is complete, jaw surgery is performed to produce normal tooth function and aesthetics. The repositioned bone is held in position during healing with various small internal metal devices. These devices, except on rare occasions, are retained indefinitely. The patient, however, is able to talk and open the mouth. Orthognathic surgical procedures are safe and predictable.
Surgical complications are minor and uncommon.
Patients should expect significant swelling and bruising during the first two weeks following surgery. When the lower jaw is repositioned, a period of lower-lip numbness or tingling is present and may last for weeks or months. On rare occasions, this altered lip feeling may persist indefinitely. Following removal of the orthodontic braces, the patient can expect a stable cosmetic and functional improvement. Because of the complexity and length of the surgical and orthodontic treatment, patients must be highly motivated and well-informed about the importance of their participation in treatment.
