Abstract:
1. An occlusion evaluation apparatus comprising an input device, an arithmetic device and a display device, wherein the input device is configured to input three dimensional data of geometries of maxillary molar teeth and mandibular molar teeth into the arithmetic device, the arithmetic device is configured to determine a geometry of a fluxion space which is defined between occlusal surfaces of the maxillary molar teeth and occlusal surfaces of the mandibular molar teeth when the maxillary molar teeth and the mandibular molar teeth are occluded, and to slidingly moves the maxillary molar teeth and the mandibular molar teeth with respect to each other to change an occlusal condition arbitrarily so that the geometry of the fluxion space is changed, and the display device is configured to display the geometry of the fluxion space in a visible manner, and to change the displayed geometry of the fluxion space in response to the change of the occlusal condition.
