Abstract
A possibility of artificial fabrication of ceramic model tooth which has a machinability similar to natural human tooth was experimentaly discussed. Comparison among many physical properties and the machinability of ceramic model tooth with the natural human tooth showed that such a model tooth can be made artificially. Then important factors were pointed out, i.e., (1) proper combination and blending of raw materials for ceramic commercial porcelain, and (2) proper controlling of firing temperature for densification.
