Many operative methods have been devised for surgical orthopedics of the mandibule, of which methods sagittal split osteotomy of the mandibular ramus is now in the most frequent use. The author has a preference for Obwegeser-Dal Pont method for those cases which require rotation of the mandibule in addition to its forward and backforward sliding. However any of these methods needs 6 to 8 weeks of intermaxillary fixation with wire ligatures, which gives the patient a great deal of physical and mental distress, while Spiessl devised a method in which instead of intermaxillary fixation. The fixation is made with cortex bone screws of A.O. Osteosynthesis, which need, however, to be removed about one year after operation. Then, Seto prepared single crystal alumina ceramic screws requiring no removal, which he is actively putting in clinical use. Favored with an opportunity to use such ceramic screws, the author made clinical studies of related cases and obtained the following resultes ; 1. Application of osteosynthetic screws resulted in several merits such as sufficient area of bone contact, shortening or disappearance of duration of intermaxillary fixation. 2. Application of ceramic screws permits doing without any removal of screws. 3. Application of this procedure to mandibular prognathism of the skeletal type and open bite led to neither lesional relapses nor anomalies of the temple mandibular joint.
