Abstract

Digital type jaw movement analyzer MM-JI is a jaw-tracking device that measures jaw movement in six-degree-of-freedom. Jaw movement data measured with this device potentially contain many diagnostic information of stomatognathic function. The current status and issues of jaw movement analysis were presented herein. Visual evaluation of jaw movement pathways and multi-variable analysis of numerical jaw movement parameters are fundamental techniques of these analyses. Combination of these techniques is essential to elicit diagnostic information from jaw movement data. Clinical application for diagnosing temporomandibular disorders and dental prosthesis were also discussed. When the development of jaw movement database and the further study of occlusion and jaw function proceed, six-degree-of-freedom jaw movement analysis will be come widely used.
