Zirconia is a modern dental replacement for the metal substructures used under conventional crowns and bridges.
Called the “white metal,” zirconia is the material of choice for creating substructures in cosmetic dentistry, to give crowns and bridges a whiter brighter more translucent quality.
In the past, most crowns and bridges had a Porcelain- fused- to-metal (PFM) substructure. These restorations, built on a dark metal alloy base, often look opaque and monochromatic, with a dark greyness at the gum line.
All ceramic restorations made with Zirconia have the natural look and translucency of natural teeth as well as being twice as strong as PFM restorations and five times stronger than other all- ceramic restorations.
Zirconia is 100% biocompatible because the body does not reject zirconia. Amalgams and metal alloys used in dentistry can cause allergic reactions not to mention mercury contamination. The body accepts zirconia as a natural material, so you don’t have to worry about allergies or adverse reactions.
