Abstract:
An object of the present invention is to provide a tooth model capable of exhibiting grinding feel similar to that of a natural tooth, with which students aspiring to become dentists experience intraoral work and perform training related to a treatment, and also experience formation of an abutment tooth, formation of cavity or the like. 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 to form an enamel portion.
