摘要：
PROBLEM TO BE SOLVED: To provide an artificial tooth with which bilateral balanced occlusion can be easily established with less grinding adjustment.SOLUTION: An angle formed by each occlusal facet with respect to the occlusal plane of an artificial teeth is appropriately set. In an artificial tooth for an upper central incisor tooth, having a protrusive facet and a retrusive facet at an incisal edge, for example, the angle formed by the protrusive facet with respect to the occlusal plane in a cross section with a sagittal plane is from 22.0° to 25.5° while the angle thereof in cross section with a frontal plane is from 1.5° to 6.5°, and the angle formed by the retrusive facet with respect to the occlusal plane in the cross section with the sagittal plane is from 20.5° to 23.0° while the angle thereof in a cross section to the frontal plane is from 1.5° to 6.5°.COPYRIGHT: (C)2013,JPO&INPIT【課題】削合調整量が少なく、容易に両側性平衡咬合の確立が可能な人工歯を提供する。【解決手段】人工歯の各咬合小面が咬合平面と成す角度を適切に設定した。例えば、上顎中切歯用人工歯では、切縁に前方咬合小面と後方咬合小面を有し、前方咬合小面が咬合平面と成す角度が、矢状面との断面における角度で22.0°~25.5°であると同時に、前頭面との断面における角度で1.5°~6.5°であり、後方咬合小面が咬合平面と成す角度が、矢状面との断面における角度で20.5°~23.0°あると同時に、前頭面との断面における角度で1.5°~6.5°である。【選択図】図1
