Simultaneous Maxillary and Mandibular Posterior Segmental Osteotomy for Correction of Scissors Bite

Abstract

This is a case report on treatment of skeletal psalidodont deformity with simultaneous maxillary and mandibular posterior segmental osteotomy. Operation was performed through only buccal mucosal incision for the preservation of blood supply to the osteotomized segments and the fixation of fragments were done using acrylic resin splint without using miniplate-screwing to avoid injuring the tooth root. Soon after the operation, temporary segmental mobility was observed. However, the usually reported postoperative complications such as relapse and disturbance of the segment or the teeth were not remarkable. Finally. the fine occlusal relationship and function were obtained.
