Why do many dentists recommend porcelain crown even though it is not good to opposite tooth? > Why do many dentists recommend porcelain crown even though it is not > good to opposite tooth? 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.

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.

How can I know if it is Empress porcelains or not? How long has it been used in dental operation? Machine milled porcelain has been around for 20 years now. Empress, I am not sure, but it has been a long time.

I don't if it is a molar. The further foward, the more it will show in the smile, so porcelain takes over. With obvious clenchers, I will still often have metal occlusal surfaces. Steve > Why do many dentists recommend porcelain crown even though it is not > good to opposite tooth? Agree with John 100% Steve Depends on the type of porcelain used.
