[The importance and technic of temporomandibular joint positioning in the sagittal splitting of the mandible].

The rigid fixation of segments in orthognathic surgery offers the advantage of avoiding long-term rigid intermaxillary immobilisation and reducing in-hospital treatment time and the entire clinical course. Nevertheless, it is difficult or even impossible to correct postoperatively osteotomy segments. Therefore the exact transfer of the preoperative position of the condyle to the postoperative situation is essential for the use of this technique and its use in bimaxillary surgery. The presented technique, which has been successful in the cooperation of orthodontics and orthognathic surgery for many years, is a prerequisite for an up-to-date treatment of dentofacial anomalies.
