Zirconia or zirconium is the hardest known ceramic in industry and the strongest material used in dentistry. The zirconia used in dentistry is zirconium oxide, which has been stabilized with the addition of yttrium oxide.

Zirconium is a very hard white ceramic that comes in the form of solid blocks of various shapes and sizes. For processing, it requires sophisticated computer systems (CAD/CAM systems).

Features and benefits

Zirconium is a recently emerged material that has revolutionized dentistry. Because of its exceptional qualities, it can be utilized for various purposes.

  • Zirconia is extremely durable and tough. It's basically the strongest material used in dentistry to this point.

  • Because it is a white ceramic with very good translucency features, zirconium restorations are highly aesthetic because they do not contain any metal in their structure.

  • The zirconia core structure can be layered with aesthetic porcelain to create the final color and shape of the tooth.

  • Similar to gold, it is very well tolerated by the body, has no allergic effects and, because it is not a metal, it never corrodes.

  • Because they are executed by computer systems, zirconium-based prostheses are highly precise.

  • Unfortunately, it is still extremely expensive. Both the material itself and the necessary processing equipment lead to a high final cost.



Base material for porcelain restorations

  • Almost any type of fixed prosthetic restoration can be constructed using porcelain fused to zirconium. The structures are extremely durable and resistant and have excellent aesthetics.

  • porcelain crown with zirconia substructure

  • zirconia against metal base restorations

  • In this situation, the zirconia core structure is layered with porcelain and is mainly used for anterior (front) teeth where aesthetics is the top priority.

Full zirconia restorations

  • Because bond strength of layered porcelain fused to zirconia is not so strong, crowns and bridges may be entirely constructed of the zirconia ceramic with no aesthetic porcelain layered on top.

  • full zirconia crowns and bridges

  • The restorations will have a white color and they are mainly indicated in areas where aesthetic demands are not extremely high.
