Management of skeletal open-bite deformity in edentulous patients.
ABSTRACT Surgical preparation of the edentulous individual with a skeletal open-bite deformity is a challenging problem to the prosthodontist and the oral surgeon. Preoperatively, there is inadequate maxillomandibular space for the prostheses. Postoperatively, the open-bite deformity may return unless the defect is properly diagnosed and surgically altered. Preoperative and projected postoperative radiographic evaluation, articulated diagnostic casts, and the combined opinions of the involved clinicians are utilized in planning the surgical procedures and the design of surgical splints and dental prostheses. Vertical osteotomy of the ramus or a variation is the desired surgical procedure. Coronoidectomy may also be necessary, depending upon the amount of posterior or inferior movement of the mandibular angle. Management of open-bite deformity in an edentulous patient is presented as an example.
