The Pursuit of Zirconia Esthetics: Innovations in Zirconia Structure, Design, Translucency and Shade Gradation
Capitalizing on the outstanding physical properties of zirconia, the profession has widely embraced the monolithic concept for ceramic prostheses ranging from single crowns to complete-arch implant supported screw retained prostheses. CADCAM systems can produce exquisite posterior occlusal anatomy, exceptional accuracy, standardization, efficiency and simplification of processes. In pursuit of more life-like optical properties, manufacturers have introduced a variety of novel innovations in ceramic structure, milling disk/block structure and shade gradation, shading technologies and unique ultra-thin layering materials. This presentation will survey and critically evaluate currently available strategies for state of the art esthetics in monolithic zirconia.
