INTRODUCTIONClass II division I malocclusions are the most common dentofacial deformities seen in clinical practice. Severe cases or cases in which growth has ceased may require full correction combining orthodontic and surgical treatment. We report a case of a total mandibular subapical alveolar osteotomy, performed to correct a class II division I dentofacial deformity. CASE REPORTA 19-year-old female patient was referred to the oral and maxillofacial surgery department at the Federal University of Paraná with chin aesthetic complaints as well as class II malocclusion. The proposed treatment was total mandibular subapical alveolar osteotomy, retaining the chin position and eliminating the need for genioplasty, since, although the patient presented with a class II dentofacial deformity, the chin was well positioned. Under general anesthesia, a "V-shaped" incision was conducted from the right retromolar region to the left retromolar region. A ring of cortical bone was removed around the mental foramen, with the aim to create a space around the mental nerve. Fixation was conducted with plates and screws of the 2.0 system. The patient on six-year follow-up showed osteotomy stability, a better overall occlusion, and outcome satisfaction.
