This study investigated the changes of the masticatory function, after sagittal splitting ramus osteotomy for mandibular prognathism.<BR>1. Masticatory efficiency was measured by means of a gravimetric sieve analysis, after masticating raw rice weighing 2.0 g on the habitual chewing side. The masticatory efficiency tended to improve following the operation.<BR>2. Absorbance of the filtrate was measured, after masticating the ATP particle weighing 5.0g on the usual chewing side and diluting it with water. The absorbance of the postoperation group tended to increase.<BR>3. Occlusal contact area using a silicone impression material was measured. The occlusal contact area of the post operation group was enlarged.<BR>After orthognathic surgery, the masticatory function of mandibular prognathism tended to improve by means of investigating the masticatory efficiency, absorbance of the filtrate using ATP particle, and the occlusal contact area.
