This zirconia-based all-ceramic crown replaces a metal crown. Also known as artificial diamond, Zirconia is made of the highest-strength fine ceramic called zirconium oxide (ZrO2).Because of its strength, it is widely used from the space industry to medical technology.he left photograph is a porcelain-fused-to-metal crown, and the right photograph shows a zirconia all-ceramic crown, Lava frame.
