    Intended Use

    The Obsidian™ Press ceramic is used to fabricate Press Over Metal dental prostheses in the nature of crowns and bridges as well as monolithic dental prostheses in the nature of crowns, veneers, inlays, and onlays for posterior and anterior applications, as well as 3-unit anterior bridges (including pre-molar region as terminal abutment) using pressing methods.

    Device Description

    Obsidian™ Press is a lithium silicate ceramic to be supplied in the form of ingots to be pressed to temperature in various furnaces. The increased Obsidian™ Press CTE value is intended to allow the Obsidian™ Press ceramic to be used in Press Over Metal applications, using various approved dental alloys, in addition to the all ceramic applications. The ingots are designed to be pressed into a variety of restorations including Press Over Metal (POM) such as full contour crowns and bridges, as well as monolithic all-ceramic restorations such as full contour crowns, up to 3-unit anterior bridges (including pre-molar region as terminal abutment), inlays, onlays, partial crowns, and veneers with esthetics, translucency, and strength. The ingots will be available in the commonly used VITA Classical and Chromascop Bleach shades.
