The zirconia or YSZ (Yttria stabilized zirconia), glossy, white, like titanium, is a solid material at room temperature, although it becomes hard and brittle at lower temperatures
The zirconia is an innovative system for aesthetic prosthetic restoration without metal frame
This material is produced by means of the latest digital computer technology CAD / CAM
Advantages :
• The status of being translucent ensures perfect aesthetic results
• Mechanical strength
• Biocompatibility (no allergic reactions)
• High resistance to corrusion
• It’s the most powerful and hard material
• Eliminates unpleasant sensitivities (hot, cold)
Disadvantages :
• High cost
• Less resistance to vibration compared to metal alloy
