  • Amann Girrbach zirconia block

    Thriden zirconia block is presintered 3mol% yttria (Y2O3) stabilized zirconia (ZrO2) block, which is made from the finest nano zirconia powder by dry and cold isostatic pressing and machining.

    Thriden high translucent zirconia(or called Ice) is used for copings or in restorations, translucent is more than 30%.
    Thriden super translucent zirconia (or called Prettau) is used for full contour or full solid zirconia crown, copping or bridge in the aesthetic zone, translucent can be more than 40%.
    Blocks are 100% suitable with Amann Girrbach ceramill system.

    Finest powder: Easy to cut, no porcelain breakage, less scraps, excellent biocompatibility and aesthetics. 
    Dry and cold isostatic pressing: fully densify,  uniform lifetime compressive strength,
    Scaling factor: carefully determined in each batch persistent and consistency,
    Coloring: imagination permeability coloring not only stay on surface.
    Package: each block in one box
