Dental implant alloys are used in dental restorations including inlays, onlays, crowns, bridges, posts, implants and superstructures. These metals can vary greatly in composition. Porcelain alloys may be better suited for inlays and onlays whereas a gold alloy may be the choice for a crown. Different alloys are better suited for specific restorations, features like hardness, precious metal composition, corrosion-resistance, and biocompatibility should be considered when choosing a dental implant alloy. Casting temperatures fluctuate between 1,200° C and 1,400° C. Esthetics are also a concern and a large selection of colors are available for perfect matching as well as yellow and white gold alloys. A certain amount of trial and error will be necessary to find your favorite dental implant alloys to work with, however, a dental implant alloy should always be reliable and strong.
