title: Surgical intervention to reestablish adequate intermaxillary space before fixed or removable prosthodontics.
abstract: Supraeruption of the right maxillary molars and concomitant drop of the alveolar ridge resulted in loss of intermaxillary space. With the patient under local anesthesia and intravenous sedation, a posterior segmental osteotomy was performed, on an outpatient basis, to reposition this segment superiorly into the maxillary sinus. Stabilization was accomplished with a prefabricated acrylic splint. The patient quickly resumed her daily routine with normal postoperative healing and satisfactory intermaxillary space.
