This case report presents a 39 years old female adult patient which diagnosis was skeletal Class II and dental Class III malocclusion with severe bimaxillary protrusion, chin deficiency and two maxillary supernumerary teeth over premolars area. The treatment plan were combined with orthodontic treatment and orthognathic surgery including bimaxillary anterior subapical segmental osteotomy, posterior subapical segmental osteotomy over right mandibular area and genioplasty. The treatment was finished in Angle’s Class I occlusion of both canine and molar relationships. Patient had normal overjet and overbite, lips competency and her facial esthetic have improved a lot. We also make some discussion about the treatment plan, the subapical segmental osteotomy and the ratio between the lip retraction and incisor movement.
