The clinical evaluation of the mandibular kinesiograph at the pre and postorthognathic surgery 2

Correlation between preoperation and one year after the operation

Abstract

The function of the jaw corrected by saggital mandibular osteotomy has been checked by mandibular kinesiograph (MKG). The data of the MKG taken one year after the operation was compared with the preoperative one. The mandibular movement at the preoperative stage showed various kinds of qualitative pattern compared with that of the postoperative data. The postoperative results indicated improvement in the mandibular movement and no subjective abnormal feature could be found. Thus, it seems that sagittal reposition of the mandible will improve mandibular function.
