Zirconia restorations
Zirconia restorations are made from zirconium dioxide, a white powdered ceramic material. Its ceramic properties and the fact that is milled from a single block make it a strong dental prosthetic. In fact, its strength allows for far thinner dental crowns than those made with metals. Zirconia restorations have excellent strength while being fully ceramic and are made by CAD CAM technology, hence they offer enhanced precision and fit while having great aesthetics.
