The occlusal plane angle is an important factor in lateral facial aesthetics. Low occlusal plane facial profiles appear planar and long-faced, whereas high occlusal plane facial profiles are considered more attractive, especially in Asian regions. Clockwise rotation of the occlusal plane for truly aesthetic purposes can be accomplished with double jaw surgery, without need for orthodontic treatments. Patients with normal occlusion who desired to improve their lateral facial aesthetics were included in this study. A conventional Le Fort I osteotomy was followed by a sagittal split ramus osteotomy under general anesthesia. The movement of the maxillomandibular complex was determined in accord with a preoperative analysis. From 2015 to 2017, 43 patients with normal occlusion underwent double jaw surgery without orthodontic treatment. Whereas all patients were subjectively satisfied with the surgery, two underwent orthodontic treatment to correct mild occlusal discrepancies noticed after surgery. There were no delayed occlusal problems or relapses reported during the study. For patients who desired to improve their lateral facial aesthetics but had normal occlusion, orthognathic surgery without orthodontic treatment can be effective. Clockwise rotation of the occlusal plane by double jaw surgery without orthodontic treatment resulted in satisfactory aesthetic outcomes with stable and reliable long-term results.
