Zirconia is the most current dental replacement for the older metal substructures used under conventional crowns and bridges.
Zirconia is called the “white metal” and is the material of choice for creating substructures in cosmetic dentistry. It gives crowns and bridges a whiter, brighter, and more translucent life-like quality. In the past, most crowns and bridges had a Porcelain-fused-to-metal (PFM) substructure. These restorations were built on a dark metal alloy base, often looking 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 made from zirconium, and is from the titanium family. Titanium itself is stronger than steel.
Zirconia is 100% biocompatible with the human body.
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.
Zirconia crowns are strong, with a natural-looking white color. However, they are not as translucent as natural teeth. Zirconia is sometimes considered better-suited for the teeth further back in the mouth; the dentist may decide ceramic porcelain crowns will be the best option for patients’ front teeth. This decision will be made based on a patient’s particular case and discussed during the patient’s consultation.
