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, 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 posterior crowns, anterior 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.
The Obsidian Stain and Glaze Kits include all of the components necessary to colorize and finish glass-ceramic and zirconia restorations. With one option ideal for clinicians who mill in-office restorations and one ideal for laboratories, the kits consist of paste stains, a glaze liquid and powder, mixing palette, and brush. The chairside version contains shades A, B, C and D, and the colors white, blue and orange; with the lab version adding the colors black, brown, green, gray, ocher, pink, violet and yellow. The stain and glaze kits enable the user to achieve all the VITA Classical and bleach shades.
With these kits in hand, users can enhance incisal translucency, mimic natural decalcifications, add characterization, and adjust overall colorization to better match milled restorations to the patient’s oral situation. The Obsidian stains and glazes have an optimal thermal expansion value, which helps ensure restorations are both strong and esthetic after final firing. Refills of all the included components are available through your distributor.
