White zirconia
Ultra-high bending strength and hardness
Comprehensive indications, especially for the long span bridge.
The excellent masking effect can be used for covering the metal color.
Bloomden’s zirconia discs are designed for use in dental laboratories and milling centers for the production of crowns, copings, bridges and custom abutments. Discs with increased as well as ultra-high transparency are available. Ultra-high transparency discs have a light conductivity of 37%. Zirconium discs are made of fine powder, which ensures the highest quality zircon with flexural strength up to 1350MPA.
