How to Choose the Right Zirconia Block for Crowns & Bridges?
Modern Zirconia presents higher translucent properties, better aesthetics, and the possibility to be used in a variety of ways; therefore, it can be applied in making crowns, veneers, bridges, and even in full-arch cases. The options are High Translucent (HT) and Super Translucent (ST/SHT), on one end, to the high-strength monolithic Zirconia (>1100 MPa) and multilayer 3D/5D/9-layer blocks, on the other. Anterior crowns get the advantage of 600–800 MPa super-translucent materials, while posterior crowns and long-span bridges need to be of 1000–1200+ MPa strength. Multilayer possibilities not only improve color matching but also minimize the number of staining phases.
