Empress is not used on PFM (porcelain fused to metal) crowns.

Empress is a hybrid material.

Machine milled ceramic has the same surface hardness as human enamel.

Eshetics.

There is no one perfect restorative material. They all have their benefits
and disadvantages. The best material for a crown, in my opinion, is gold.
However, most people don't want a gold coloured crown to replace a tooth in
a visible area, despite the fact that porcelain can cause an increase in
wear to the opposing dentition. You should know that some of the newer
porcelains, such as Empress, are said to have a wear rate similar to enamel.
