Abstract
A 23-year-old female whose chief complaint was asymmetric prognathism with temporomandibular joint disorder (TMD) underwent surgical orthodontics using sagittal splitting ramus osteotomy. A symmetric skeletal relationship and good occlusion were obtained. MRI and tomogram were taken before and after the treatment to evaluate condylar position. Concomitantly condylar movements were recorded with maximum opening and protrusion-retrusion of the mandible by means of a computer-aided diagnostic axiograph (CADIAX). The results indicated that the distance of condylar path tracing in maximum opening and protrusion movements decreased and the asymmetry of condylar movement was corrected after surgerv.
