What types of metals can be used to fabricate porcelain-fused-to-metal crowns?
There are a number of different dental alloys that can be used to fabricate a porcelain-fused-to-metal dental crown (PFM). And as you might expect, the physical characteristics of each alloy will play a big role in determining which is chosen. For example, clearly the metal must be strong enough so it can adequately support the porcelain that lies above without flexing. Also, the strength and predictability of that bond the metal can create with porcelain is of utmost importance. Your dentist will probably have a strong opinion about which type of metal they will want to work with. This opinion will be based on both their knowledge and past experiences. The same classification system used to categorize alloys for all-metal dental crowns is used with PFM crown materials.
