Preshaded zirconia blanks：

Preshade zirconia blanks are researched and manufactured by Xiangtong Medical Corportion. We select high quality exported zirconium powder, mixing with different colored powder, pressing ,shaping ,pre-sintering to make the zirconia blanks , helps solve the problems like uneven colors , spot, over obvious and negative color difference between the front and the back.

The zirconia blank is non-toxic and non-radioactive with excellent biological properties, teeth color is like the real teeth with good permeability and aesthetics. It is with high strength, good toughness and excellent wear resistance, X-cera pre-shaded zirconia blank is the raw material with excellent property for making crowns.
