Abstract

Sagittal split ramus osteotomy is one of the most efficient steotomy techniques for orthognathic surgery. This technical note presents a new technique of mandibular osteotomy to prevent bony interferences with simultaneous maxillary impctions. As well as increase in bone contact for great mandibular advancements which results in better bone healing. furthermore, Fixation of bony segments in this area is far from third molar alveolar socket if extraction is done and is not involved in the process.
