For successful orthognathic surgery, a good coordination between the maxillofacial surgeon and the orthodontist is essential. Especially, it is important for the orthodontist to correct the anteroposterior position and inclination of the maxillary incisors during presurgical orthodontic treatment to achieve the maximum esthetic results. Most orthodontists used cranial base structures (e.g., Steiner’s SN plane and Ricketts’s FH plane) to measure the anteroposterior position and inclination of the maxillary incisors. Unfortunately, if these planes were flat or steep, surgery methods could be changed or it could result in less than desirable facial outcomes. To overcome this disadvantage, this study suggests that the inclination of the maxillary and mandibular incisors to occlusal plane should be used to establish the position of incisors. A case treated by this method is presented and advantages of this approach are discussed.
