The metal substructure of a porcelain-fused-to-metal crown can be made out of any one of a number of dental alloys specially formulated for this purpose.
Types of alloys.
The same classification system that is used to categorise alloys for all-metal dental crowns is used with PFM alloys too.
a) High noble (precious).
High-noble alloys have a composition that is over 60% gold, platinum and/or palladium. These alloys have the advantage that they are the easiest and most predictable to work with. Using them usually ensures the most accurate crown fit and the most predictable metal-to-porcelain bond. They however, are also the most expensive to use.
b) Noble alloys (semi-precious).
Alloys in this group have a noble metal content (gold, platinum and/or palladium) that is over 25%. They are similar in their predictability of bonding and a fraction of the price of High Noble.
c) Base (non-precious).
These alloys have a formulation that is less than 25% noble metal. They were in the past littered with allergens but the CoCr Non Precious materials have come on in leaps and bounds. One manufacturer in particular, BEGO has developed a material that ensures a great fit and also a very predictable metal to porcelain bond.
