The present case report describes the treatment protocol for Class III malocclusion with ante–rior open bite in adult, a novel orthodontic– surgical approach. A 24–year old male patient with a Class III malocclusion, anterior open bite (skeletal), poor facial aesthetics, mandibular and chin protrusion. Patient had significant anteroposterior as well as transverse discrepan–cies, with a concave profile, and strained lip closure. On intra–oral examination the patient had an open bite extending from first molar on one side to the first molar on the other. The treatment objectives were to correct the skeletal open bite, occlusion as well as facial aes–thetics. Orthodontic mini implants were used to facilitate intrusion of first molars to a certain extent. The surgical procedures included a bilateral sagittal split osteotomy which was per–formed in order to allow counter–clockwise rotation of the mandible and anterior projection of the chin, accompanying the maxillary occlusal plane.
