Although ostectomy has been proven in numerous studies to be an effective means of reducing pocket depth, some clinicians still question its merits. To determine the efficacy of ostectomy for the treatment of periodontitis, 870 pairs of presurgical and postsurgical radiographs of sites treated by ostectomy were examined. The postsurgical radiographs, taken 5 to 30 years postoperatively, revealed distinct lamina dura and demonstrated that ostectomy is an effective and predictable technique for intercepting the progressive loss of attachment in selected sites with periodontitis.
Rehabilitation of patients with severe dental wear is a complex diagnostic and restorative problem. As wear occurs, space for restorative materials is lost, and unique treatment techniques are needed to provide good esthetics and function. Use of orthognathic surgery to reposition mandibular anterior teeth and supporting alveolar bone can create a more ideal environment for restorative procedures.
A modified technique of anterior maxillary osteotomy is described, based mainly on the Wassmund (buccal aspect) and the Wunderer (palatal aspect) methods. Experience of 148 cases operated on during 15 years is presented.
