<p>PURPOSE: Porcelain-fused dental metal alloy and a dental prosthetic material are provided to prevent the deformation of palladium-indium-gold-silver alloys during high-temperature plasticization with ceramic porcelain by properly regulating the alloy components. CONSTITUTION: A porcelain-fused dental metal alloy comprises gold(Au) over 0 and less than 35 weight%, silver(Ag) of 5-35 weight%, indium(In) of 6-40 weight%, and palladium(Pd) of 30-70 weight%. The metal alloy also includes one or more elements selected from the group consisting of boron(B), germanium(Ge), zirconium(Zr) silicon(Si), and iron(Fe).</p> |
