The use of orthognathic surgery to facilitate implant placement: a case report.

: When attempting to restore an edentulous posterior segment of the mandible into which space the opposing maxillary segment has supererupted, it is necessary to idealize the maxillary occlusal plane to accommodate the final restoration. This report discusses superior repositioning of the posterior segment of the maxilla using rigid fixation with simultaneous implant placement into the corresponding posterior edentulous mandibular space.
