E.max crowns are called cast ceramic teeth, also known as all-ceramic restoration. It is made of a new ceramic material that can be cast. It is superior to PFM teeth in appearance and biological properties. The inner crown of E.max is porcelain, a transparent skeleton with no metal base layer. People choose E.max for good reasons:
- Completely bio-compatible (even better than gold alloy).
- High & consistent translucency, the most natural-looking of all
- Basically no wearing to the opposing natural teeth
