ABSTRACT:
A dental alloy for use in porcelain-fused-to-metal restorations including palladium, cobalt, indium, tin, aluminum and rhenium. The aluminum protects the alloy during torch melting and during the porcelain firing process through the formation of a protective oxide. The rhenium provides grain refining for the alloy to increase its elongation, tensile strength, and thus toughness. The alloy must be made under vacuum or in an inert atmosphere to avoid the formation of bubbles in the porcelain during the porcelain firing process.
