ABSTRACT:
A surface treatment material used in fusing dental porcelain, containing powder of gold terpene sulfide, is applied and sintered on a metal frame. Then, the terpene and sulfur oxidize to suppress oxidation of gold and the like. A surface treatment layer having no coat, is thus formed on the surface of the metal frame with the alloy component of the metal frame and gold being bonded and combined with each other in a diffusion and solid solution manner. Then, it is fused with a dental porcelain built up on the surface of the metal frame on which the surface treatment layer is formed.
