摘要： An object of the present invention is to provide a dental polishing instrument that causes no clogging, that prevents occurrence of any secondary flaw, that is excellent in the polishing property, and that can provide high gloss in a short time period, for a dental prosthetic appliance difficult to polish. Another object thereof is to provide a dental polishing instrument that enables easy discharge of polishing sludge while that simultaneously shows sufficient strength. A dental polishing instrument according to the present invention can suppress clogging and occurrence of any secondary flaw due to the polishing sludge and can efficiently polish by forming a polishing abrasive grain layer including polishing abrasive grains and a resin material, into protrusions on the surface of a base material thereof and by disposing the protrusions on the base material.

摘要： 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.

摘要： An artificial tooth where an occlusal surface is formed by grinding has a reference point that represents a position and an angle of the artificial tooth when an occlusal surface of the artificial tooth is obtained by an occlusal-surface form measuring apparatus. The reference point is a convexed spherical surface or a concaved spherical surface arranged on the occlusal-surface. The spherical surface has three or more reference points. The convexed spherical surface is fit to the concaved spherical surface when the maxillary artificial tooth and mandibular artificial tooth are occluded. The occluding portion of the artificial tooth has a grinding portion.
