In the field of jaw deformities, there has been an increase in the number of middle-aged and elderly patients selecting surgical correction in recent years. However, treatment of these patients might be difficult because of poor oral condition such as edentulous jaws and tooth loss. Under these conditions, an interdisciplinary approach including orthodontics, oral surgery and prosthodontics is required for the treatment of jaw deformity. We report a patient with edentulous jaws who was treated with orthognathic surgery using the interdisciplinary approach.The patient was a 42-year-old male diagnosed with mandibular protrusion. He was at risk of chronic diseases of the mouth, including dental infection and tooth loss. As a result of diagnosis of prosthodontics, all teeth were extracted to correct severe oral hygiene. Before corrective jaw surgery, wax dentures were made on the assumption of post-surgery oral condition. By using the wax dentures, dental implants were positioned on the edentulous jaws and provisional teeth were made. Regarding orthognathic surgery, intraoral vertical ramus osteotomy was performed on the right side of the mandible and sagittal split ramus osteotomy was performed on the left side. Twelve months later, osteotomy was performed and the final stage of prosthodontic treatment was started.Following this interdisciplinary approach to jaw deformity treatment, the patient with edentulous jaws is satisfied with the stable occlusion and better facial contour.

A case of maxillofacial asymmetry involving (a) asymmerty of the mandibular bone, (b) lateral inclination of the occlusal plane of the maxilla, and (c) functional displacement of the mandible. The authors performed a sagittal splitting ramus osteotomy, to correct (a) and (c) and also the extrusion of maxillary buccal segments to correct (b).The fixation was six weeks after the surgery released, and the maxillary occlusal plane was leveled to extrude the right maxillary buccal segments.The treatment achievements were satisfactory.The case maintained a stable occlusion without relapse.
