摘要： A method of manufacturing a dental prosthesis, including: (a) a step of preparing a substrate of the dental prosthesis that is constituted by a dental molding material; (b) a step of forming a back coating layer on at least a part of a surface of the substrate, by using a first porcelain that is constituted principally by ceramic; (c) a step of forming a casting mold such that the substrate is disposed in the casting mold and such that a void is provided on a surface of the back coating layer; and (d) a step of forming a cast coating layer on at least a part of a surface of the back coating layer, by pouring a second porcelain into the void at a casting temperature. The second porcelain is constituted principally by ceramic whose composition is different from that of the ceramic of the first porcelain that viscosity of the second porcelain at the casting temperature is lower than that of the first porcelain. Also disclosed are a kit and a dental porcelain set that are used for manufacturing the dental prosthesis.
