Abstract

This study investigated the pre and post-operative changes of mandibular movement by means of mandibular kinesiograph for mandibular prognathism which indicated sagittal splitting ramus osteotomy. After surgery, the following was observed.
1. On the frontal plane for habitual opening and closing movement, the condition of asymmetry or deviation decreased.
2. The smoothness in the opening and closing movement speed increased.
3. There was no notable change observed in the stability of rest position or the relation ship between the rest position and intercuspal position.
4. On the frontal plane of the lateral gliding path, the angle of the path tended to resemble that of the normal group.
