PFM – Porcelain Fused to Metal

PFM crowns are a tried-and-true restoration that provides strength and durability. Porcelain fused to metal can be used for single anterior and posterior crowns and bridges, it can also be designed to fit any type of preparation as well. PFM restorations are also indicated for crowns and bridges used in combination with cast partials. Porcelain can be fused to non-precious, semi-precious or white high noble copings.

Types of alloys – The metal substructure of a PFM can be made out of different classifications of dental alloys.

High noble – Precious. These alloys have over 60% gold, platinum and/or palladium content. High noble metal is one of the easiest alloys to adjust. Yellow gold high noble metal offers the best aesthetics over any other PFM restoration. We offer PFM crowns in both yellow and white gold high noble restorations.
Noble alloys – Semiprecious. These alloys have over 25% noble metal (gold, platinum, palladium) content. Noble metal crowns offer a more hypoallergenic restoration over base metal crowns at a more affordable cost over high noble crowns.
Base – Nonprecious. Contains less than 25% noble metal. Base metal alloys are considered to be the most economical PFM restoration. Many base metal alloys contain nickel, chrome, and/or beryllium alloys.

Cementation
