The maxillary incisors were labially inclined and the molar relationship was Angle Class III. This patient was diagnosed as having mandibular protrusion and large lower facial height. After extraction of the maxillary first premolars, 0.018 inch pre−adjusted edgewise brackets were placed to treat the compensated upper incisor inclination and minor crowding. Orthognathic surgery , sagittal splitting ramus osteotomy, was performed at 26 years 10months and genioplasty was performed at the removal of mini−plate fixation of the mandible at 27 years 8 months. After post−surgical orthodontic treatment, the facial profile was significantly improved, and an acceptable occlusion was achieved. No relapse was observed after two years of retention.}, pages = {30--35}, title = {大きな下顔面高を伴う骨格性下顎前突の1症例}, volume = {38}, year = {2012} }
