    摘要： A denture grinding machine includes: a denture-holding table for holding dentures; a grinding tool for grinding the dentures held on the denture-holding table; a main body for holding the grinding tool; a moving mechanism for causing relative movement between the denture-holding table and the main body; and a driving mechanism for relatively driving the main body and the denture-holding table. The moving mechanism moves relatively the denture-holding table and the main body in three-dimensional coordinate directions based on grinding portion data, and the grinding tool performs grinding of the denture occlusal surface from a direction perpendicular to the occlusal surface.

    摘要： An occlusal wear evaluation apparatus capable of evaluating quantitatively an occlusal wear of a used denture reads three dimensional data of a denture before use and three dimensional data of the denture after use, calculates a difference in a set value of an articulator allowing the maxillary dental arch and the mandibular dental arch of the denture to occlude between the denture before use and the denture after use, by way of stimulating 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.
