Zirconia Layered has beautiful, natural looking esthetics, and are extremely strong for multi-unit* bridges where IPS e.max cannot be used. A precious metal alloy contains 40% gold. 5,8 There are many advantages to Multi-Layered Full Contour Zirconia restorations, other than decreased wear of the opposing dentition and greater translucency . The actual mechanism of bonding ceramic to zirconia substructures is not completely understood, nor is the manipulation of surface treatment of zirconia in the quality of the bond. Solid zirconia does not have the same level of esthetics as the layered version, but what is lacks in esthetics, it makes up in sheer strength. However, the final choice depends on the patient's dental . The most accurate code, whether zirconia crowns or e.max, is D2750 crown—porcelain/ceramic substrate.
