Sagittal Split Osteotomy of the Mandible without Postoperative Intermaxillary Fixation: A Clinical and Cephalometric Study

Abstract

A modified sagittal split technique has been evaluated in 42 dentate patients, in whom no postoperative intermaxillary fixation was used. Twenty-three patients had mandible set-back performed and 19 patients mandibular advancement. The method makes possible a safe split osteotomy under controlled conditions. The design of the osteotomy and screw osteosynthesis counteracts relapse. Omitting intermaxillary fixation facilitates postoperative handling of the patient and promotes rehabilitation.
