3D Multilayer Zirconia Blanks
Our zirconia blocks are compatible with different kinds of CAD/CAM
system and manual system, such as Cercon system, Sirona Inlab
system, KaVo system, Wieland system and Amann Girrbach AG system.
We choose the best zirconia powder and utilize a cold isostatic
pressing system to form shapes,the main advantage of isostatic
pressing is the uniform application of pressure, which lead to a
very homogeneous density and shrinkage,yielding a very reproducible
process.The production cost by using isostatic pressing is much
higher than uniaxel dry pressing, but quality is also much
higher.We try to provide high quality ,low cost zirconia blocks for
all dental CAD/CAM milling system, support open architecture
CAD/CAM milling system. We will sell lowest price on zirconia
blocks and highest quality to all labs worldwide.
