A Case of Reoperation for Old Mandibular Fracture

Analysis of the Stomatognathic Function

Abstract

The purpose of treatment of jaw fracture and deformities is to improve the appearance and stomatognathic function of the oral and maxi ilofacial region. Morphological examination has been performed extensively in the orthodontic field; however, objective functional assessment methods for the masticatory system are few.
The patient, a 19-year-old female, was referred to us and complained of occlusal discomfort and man-dibular deviation. We performed open reduction of the malunion fracture and evaluated the stomato-gnathic function, i. e., occlusal contacts in intercuspal position and muscle contraction pattern during gum chewing, by means of medical engineering instruments pre and post operatively.
