    Intended Use
    Coloring Liquid is a liquid used for the complete or partial coloration of milled zirconia substructure and anatomy before sintering.
    Device Description
    Coloring Liquid is water based, which consist of watery, acidic metal salt solutions. They are used for the individual staining of dental zirconia frameworks and restorations prior to the final sintering of the restoration, enabling the user to adjust the restoration to match the natural color of the patient's teeth. Coloring Liquid is provided in 45 different shades, which are corresponding to patient's closest tooth color. For staining, the zirconia materials have to be immerged into the liquids or to be brushed with the liquids, prior to sintering at high temperatures

    Intended Use
    X-cera Pre-shaded Zirconia Blanks are Intended for use with CAD/CAM technology to produce all ceramic dental restorations as prescribed by a dentist. All blanks are processed through dental laboratories or by dental professionals
    Device Description
    "X-cera Pre-shaded Zirconia Blanks" is derived from zirconia powder that has been processed through various molding and sintering techniques - into their final net shapes. These blanks are then further fabricated into various prosthetic dental devices intended for use in the production of artificial teeth in fixed or removable dentures, or for jacket crowns, facings, and veneers. The zirconia powder is composed of ZrO2+ Y2O3 + HfO2+ Fe2O3+ Er2O3+ Al2O3. The performance of formed zirconia dental blanks conforms to ISO 6872, Dentistry, Ceramic Materials. "X-cera Pre-shaded Zirconia Blanks" is ceramic dental blanks designed for the manufacture of ceramic dental prosthetic devices. The dental prosthetic devices are fabricated by CAD/CAM machining processes. All prosthetic dental devices are intended for single use applications. At the dental lab, the blanks are held to the CAD/CAM machine which is used to machine to the final dental restoration. At the completion of the machining steps, the dental restoration is fired (i.e., sintered) in the oven to harden the ZrO2 so that its final properties can be achieved. "X-cera Pre-shaded Zirconia Blanks" is supplied in different shapes, such as blocks, discs, rods, or customer ordered shapes. It is also supplied in the combinations of forty nine different colors. The different colors are originated from the different constituent of color additives (such as Fe2O3, Er2O3).
