Zirconia crowns are made from zirconium dioxide, a strong and biocompatible material. Zirconia crowns are known for their high strength, excellent aesthetics, and resistance to wear and staining. They are also biocompatible, meaning that they do not cause adverse reactions in the body and are well-tolerated by patients. There are several types of zirconia crowns available, including monolithic, layered, porcelain-fused-to-zirconia (PFZ), and CAD/CAM zirconia crowns. Zirconia crowns are an increasingly popular choice among dental professionals and patients due to their excellent properties and performance.
