Bloomden St Preshaded
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 41-43%. Zirconium discs are made of fine powder, which ensures the highest quality zircon with flexural strength up to 1100MPA.
