The sagittal splitting ramus osteotomy of the mandible is widely used for the correction of various dentofacial deformities in Japan. The rigid fixation of the split bone segments seems to be main means to redure the duration of maxillo-mandibular fixation and postoperative relapse of the mandibular position. However, the skin incision for fastening the screws has some disadvantages, for example, scars, the injury of the facial artery or the injury of the facial nerve.<BR>We developed a modified technique to fix the segments bicortically with titanium screws using the contra-angular handpiece for dental implant installation. This is an intraoral fixation method without skin incision. Moreover, very slow and high torque screwing let the segments contact closely and be stable. Operations can be performed by this method without any complications and having good post operative stability.
