PROBLEM TO BE SOLVED: To provide a tooth model capable of exhibiting grinding feel similar to that of natural tooth, with which a student aspiring to become a dentist experiences intraoral work and practices treatment, and also experiences formation of an abutment tooth, formation of cavity, or the like.SOLUTION: A difference in the grinding feel between tooth enamel and dentin which constitute a natural tooth is reproduced by impregnating a sintered body formed integrally of an inorganic powder, such as, alumina with a thermosetting resin or a low melting point glass so as to form an enamel portion.COPYRIGHT: (C)2009,JPO&INPIT【課題】歯科医師を目指す学生が、口腔内作業を体験し、治療の練習をする顎歯模型用に用いる歯牙であって、支台歯形成、窩洞形成等の形体付与を体験する為に用いる天然歯と同様の切削感を示す歯牙模型の提供。【解決手段】アルミナのごとき無機粉末で一体形成された焼成体に熱硬化性樹脂または低融点ガラスを含浸させてエナメル部分を形成することによって、天然歯を構成するエナメル質とデンチン質との切削感の違いを再現する。【選択図】図1
