Abstract

An alternative surgical treatment plan was presented to show how to efficiently correct mandibular prognathism without large overjet discrepancy presented. The protrusive chin was eliminated through clockwise rotation of the occlusal plane and maxillo-mandibular complex. Within this method, no complicated orthodontic treatment was needed and the total treatment time was therefore shortened. The smiling arc was also improved. The philosophy, clinical application, long term stability, and side effects of the occlusal plane manipulation in orthognathic surgery were discussed.
