Maxillary Anterior and Posterior Segmental Osteotomy for Correction of Skeletal Open Bite

We reported a case of skeletal anterior open bite deformity treated with both maxillary anterior and posterior segmental osteotomies. The clinical and radiographic examinations indicated a stable result without relapse. Maxillary posterior segmental osteotomy for skeletal anterior open bite is an effective procedure that could correct the etiological sequence of altered mandibular protrusion, forward tongue posture, and buccal segment extrusion. In addition, combination with maxillary anterior segmental osteotomy shorten the duration of treatment.
