Maybe Dr. Rodebaugh will fill us in about it.

(No pun intended)

Yellow Dental gold is normal 14-18kt. More often 14kt for full crowns and bridge work. Small gold fillings, aka inlays and onlays are 18kt mostly. Direct gold foil fillings as seen in class 5 restorations are 24kt……but are “old school and very rare”. The cool thing about dental alloy is the other metals. Most often the other metals are mostly silver, palladium, platinum, and copper. You can expect a single crown from an average premolar or molar to weight 2-3 Dwt on average.

Crown and bridge PFM (porcelain fused to metal) have a nice esthetic tooth colored porcelain fused to a metal substructure. This metal is often an alloy of palladium, gold, and platinum. For instance I use a PFM that has a clad like structure of pure gold, pure platinum, pure gold for my fixed restorations. The metal weight of these restorations is low, but often the recoverable metal is more pure.

i have heard that it brings a lower price because its fungible with nazi victim dental gold, and many people won't buy it on principle. don't know if that is true or not but it would explain the healthy discounts you sometimes see.

hmmm, not sure, I always assumed it was beacause you would be buying "a pig in a poke". AKA...unknown alloy comp.
