PROBLEM TO BE SOLVED: To simply and quickly determine a part of denture to be ground and to easily perform grinding.SOLUTION: Artificial teeth 11, 12 where occlusal surfaces are formed by grinding have reference points that represent positions and angles 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 convex spherical surface 15 or a concave spherical surface 16 arranged on the occlusal-surface. The spherical surface is 3 or more in number. The convex spherical surface 15 is fit to the concave spherical surface 16 when the maxillary artificial tooth 11 and mandibular artificial tooth 12 are occluded. The occluding portions of the artificial teeth 11, 12 have grinding portions 13, 14.COPYRIGHT: (C)2012,JPO&INPIT【課題】義歯の削合部分を簡単かつ迅速に決定し、容易に削合を行う。【解決手段】削合により咬合面を形成する人工歯11,12であって、咬合面形状測定装置にて人工歯の咬合面を取得するときの人工歯の位置及び角度を示す標点を有する。標点は咬合面に設けた凸15または凹16の球面である。球面は3個以上有する。上顎の人工歯11と下顎の人工歯12が咬合するときに、凸15と凹16の球面が嵌合する。人工歯11,12の咬合する部分に削合部分13,14を有する。【選択図】図7
