Obsidian® Milling Blocks exceed strength requirements for cemented all-ceramic restorations. Obsidian Milling Blocks are designed with an innovative combination of over 20 unique elemental oxides chosen from the periodic table (including zirconia). Additionally, the Obsidian Milling Block owes its excellent properties due to a very high content of ultrafine nanometer-size lithium silicate and lithium phosphate crystals.
The Obsidian Milling Block is a lithium silicate ceramic, supplied in a partially crystallized (nucleated) phase, with or without an attached mandrel, which is to be milled using CAD/CAM methods.
The product can produce a variety of monolithic restorations with great esthetics, lifelike translucency and high strength, including full-contour crowns, posterior crowns, anterior crowns, partial crowns, inlays, onlays and veneers, due to its excellent machining properties.
Obsidian Milling Blocks are available in the commonly used VITA® Classical and Chromascop® Bleach shades.
The product comes in the following VITA Classical shades: A1, A2, A3, A3.5, B1, B2, B3, C1, C2, C3, D2 and D3; and Chromascop Bleach shades BL1 and BL4. After milling, the restorations must be subjected to a crystallization cycle, where they achieve great esthetics, lifelike translucency and high strength.
