Zirconia Crowns and Bridges

- Jul 05, 2018 -


Zirconia ceramic is so strong that it has applications in the aerospace and other high-tech industries. There is no need for a metal framework, and because of this, crowns made with zirconia don’t need to be opaque, and they will never show the dark gumline as porcelain-fused-to-metal crowns do.

Feldspathic crowns are created by stacking and firing multiple layers of porcelain, and zirconia crowns are milled from a single block of ceramic. Zirconia is also highly biocompatible, meaning that it virtually eliminates the risk of allergic reactions. Hip replacements use very similar materials. Because it can be milled so thin, the border where it meets the tooth has an extremely precise fit. In addition, zirconia crowns are strong enough to support bridges.
