Abstract: A method and apparatus for performing simulation display of the three-dimensional shapes and occlusal contact region of the upper and lower tooth rows at a high speed. A jaw movement sensor fits an examinee, and data on jaw movement of the examinee is acquired. An impression plate including a rigid flat plate having a top surface and a bottom surface each coated with an impression material inserted between the examinee's upper and lower tooth rows to which the jaw movement sensor is fitted, and the examinee performs a temporary occlusion. Impressions left on the impression material and a gauge mark provided on the rigid flat plate are measured by using a three-dimensional measuring instrument, whereby the three-dimensional shape data of the upper and lower tooth rows and gauge mark are acquired. Simulation display of movement of the aforementioned is performed at a time of temporary occlusion and jaw movement data.

Abstract: An apparatus for measuring a dental occlusion includes: a position sensor (30) for detecting a position and posture of a lower jaw (12) relative to an upper jaw (11) and; an arithmetic circuit (31) for computing a posture relative to a translation distance in a state of occlusal contact. The computation is derived from the position and posture of the lower jaw (12) relative to the upper jaw (11) detected by the position sensor (30). The apparatus also includes a display monitor (32) for displaying the posture relative to the translation distance computed by the arithmetic circuit (31).
