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.
