Dental alloys are used for a casting a range of restorations, copings, frames and more. These alloys can be composed of a range of noble, high noble and base metals, and each mixture offers different properties that can make one alloy ideal for a specific restorative situation and another alloy completely unsuited to the same task. Full contour crowns and bridges are most often case from noble and high noble metals such as gold and platinum, but these softer metals might not be suited for posterior crowns on a bruxing patient. A wider range of alloys can be used for casting copings and substructures for porcelain-fused-to-metal (PFM) restorations. It is important to coordinate the alloy and the ceramic systems being used for a PFM restoration. Casting dental alloys requires specific techniques with different alloys melting at different temperatures, so be sure to follow the protocols that deliver the best results for your lab.

| Description | Type IV micro-fine grain alloy that is recommended for single crowns, long span bridges and implant superstructures. Low fusing benefits. | Degubond 60 is a micro-fine grain palladium-silver alloy, which may be used with most commercial porcelains. Degubond 60 is recommended for crown and | Type III. Palladium-free for outstanding gold color with excellent tarnish resistance. PF-CB is a great multi- purpose alloy due to its combination of | Ovation develops the lightest available oxide, ensuring optimal porcelain esthetics. The copper-free formulation was engineered for high yield | A white porcelain alloy designed to compete with high palladium prices. This 65% gold alloy has no copper. A small amount of silver keeps the density |
