Abstract:
An esthetic smile is an integral feature of beauty. Improvement of the smile can be achieved by a combination of orthognathic surgery, orthodontics, and cosmetic dentistry. Preoperative evaluation serves to address a patient's surgical goals; it allows a surgeon to perform a detailed facial analysis and identify patients who are contraindicated for surgery. LeFort I and bilateral sagittal split osteotomy are performed to minimize the risk of complications. Injuries to the inferior alveolar nerve are the most common complication after orthognathic surgery, in which 90% of patients experience transient sensory disturbance of the lower lip in the postoperative period.
