| Outline of Final Research Achievements |
The present study developed the system for integrating morphological coordinates obtained with dental computer tomography and jaw movement coordinates acquired with a mandibular movement measuring device in order to enable multipoint analysis of anatomical condylar movements to be performed. The incisal paths as well as masseter and anterior temporal muscle activity were simultaneously recorded in orthodontic patients to elucidate the adaptation of TMJ after orthodontic treatment. The results suggested that adaptive bone remodeling of the TMJ might occur due to the correction of occlusion and craniofacial morphology in patients with mandibular protrusion and maxillary protrusion. Main occluding area in patients with mandibular protrusion was located in the upper first molar and the lower second molar. Spee curvature related to the posterior slope of articular eminence in the patients with maxillary protrusion.
