Abstract: The present invention relates to a computer-implemented method for detecting and displaying tooth wear using intra-oral 3D models, the method comprising a plurality of steps executed by a processor, the plurality of steps including receiving a segmented and registered 3D digital model of at least a tooth, obtaining a first and a second segmented 3D model of the tooth from scanning the tooth at a first time and at a second time, rotating and translating the first and second models of the tooth and registering a best fit rotation and translation of the first and second models of the tooth, computing a measurement of the distance between the first and second models of the tooth, detecting initial worn areas by finding vertices that have moved significantly in the negative direction, refining worn areas through morphological operations, computing changes in volume and height between the first and second models of the tooth, displaying the changes in volume and height between the first and second models of the tooth.
