Research Abstract	The function of masticatory muscles and the three-dimensional movement of mandibular bone and temporomandibular articular disc during mouth opening and shutting were analyzed using MRI. As a result, it became clear that the locus of mandibular movement and the condition of temporomandibular articular disc and the function of masticatory muscles have correlation. In addition, the software that was able to display the movement of the mandible by 3D on the computer was developed. By this software, we became able to grasp a condition of the mandibular movement visually.
