<p>PURPOSE:To enhance the processing accuracy of an artificial tooth, by injecting a molding material in the hole part of a tooth to perform impression-taking and processing and forming a base bottom hole to an artificial tooth matrix material at the part corresponding to the base bottom part of the tooth on the basis of the signal obtained by measuring a dimensional shape from the obtained mold and fixing a holder to the base bottom hole to process and mold an outer shape. CONSTITUTION:A molding material 1 is injected in the hole part of a tooth to be repaired to perform impression-taking. On the basis of the signal formed by measuring a dimensional shape from the outer mold 2 thus obtained, a base bottom hole 9a is at first processed and formed to an artificial tooth matrix material 9 at the part corresponding to the base bottom part of the tooth to be repaired. Subsequently, the outer shape dimension of the artificial tooth matrix material 9 is processed and molded so as to be matched with a outer mold shape 9b in such a state that a holder 10 is fixed and held to the processed base bottom hole 9a and an artificial tooth having no irregularity in a finish dimension is obtained.</p> |
