Abstract
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.
