PROBLEM TO BE SOLVED: To provide an occlusion contact measuring device for detecting occlusion contact abnormality such as early contact and cuspis dentis interference, early detecting misalignment in occlusion contact of each tooth, and occlusion in forward, backward, right, or left directions, and performing adjustment of occlusion to prevent occlusal trauma, periodontal disease, etc.SOLUTION: The device includes impression sampling means to simultaneously sample impressions of occlusal surfaces of upper and lower jaw teeth within an interocclusal distance from a lower jaw rest position to a center occlusal position, impression tray holding means to hold the impression sampling means, sectional displacement measuring means to measure irregularities on a sampled impression surface sampled by the impression sampling means, a control computer to store sectional displacement data measured by the sectional displacement measuring means, and to correct images, and image display means to display sectional image data after correction of images by the control computer. Occlusion contact between the upper and the lower jaw teeth is thus measured.COPYRIGHT: (C)2012,JPO&INPIT【課題】早期接触、咬頭干渉などの咬合接触異常を見つけ出し、さらに、個々の歯の咬合接触や前後左右の咬合のくるいを早期に発見し、咬合調整を行うことによって咬合性外傷、歯周疾患、等を予防し得るようにした咬合接触測定装置を提供するものである。【解決手段】下顎安静位から中心咬合位までの間の安静空隙内で上下顎歯の咬合面を同時に印象採取する印象採取手段と、該印象採取手段を保持する印象用トレー保持手段と、前記印象採取手段によって採取した採取印象面の凹凸を計測する断面変位計測手段と、該断面変位計測手段により計測された断面変位データを記憶および画像修正する制御コンピュータと、該制御コンピュータで画像修正された断面画像データを表示する画像表示手段とを備え、上下顎歯の咬合接触を測定する。【選択図】 図2
