Abstract
An occlusal wear evaluation apparatus capable of quantitatively evaluating an occlusal wear of a used denture reads three dimensional data of the denture before use and three dimensional data of the denture after use. The apparatus calculates a difference in a set value of an articulator allowing a maxillary dental arch and a mandibular dental arch of the denture to occlude between the denture before use and the denture after use, by way of simulating movements of a jaw in the articulator with the three dimensional data of the denture before use and the three dimensional data of the denture after use, and indicates the calculated difference.
