PURPOSE:To obtain the dental prosthetic appliance adequate for tooth restoration by means of crowns, bridges, etc., by constituting the compsn. of an internal layer part after sintering of specific conductive ceramics, dental porcelain and specific metals and constituting an outer layer part of dental porcelain. CONSTITUTION:The dental prosthetic appliance adequate for tooth restoration by means of crowns, bridges, etc., is constituted of the inside layer part and the outside layer part. The inside layer part is a sintered body and the compsn. after the sintering consists of 40 to 95wt.% one or >=2 kinds of the conductive ceramics selected from nitride ceramics, boride ceramics and carbide ceramics having <=10<-1>OMEGA.cm electrical resistivity, and 5 to 60wt.% dental porcelain and/or one or >=2 kinds of the metals selected from Ti, Zr, Au, Pt, Pd, Ag, In, and Sn. Further, the outside layer part is formed of the dental porcelain. |
