HT zirconia blanks are researched and manufactured by Yucera. 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.

Applicable system: wieland,sirona,kavo,lava,amann girrbach and cercon,etc.

 

Advantages of Zirconia

 High density and strength.

(1) The strength is 1.5 times higher than the second generation of EMPRESS.

(2) The strength is more than 60% higher than INCERAM alumina.

(3) Unique crack resistance and tough curing performance after cracking.

(4) Porcelain bridges with more than 6 units can be made, which solves the problem that all-ceramic systems cannot be used as long bridges.

 

Indications of HT white zirconia block

 Coping, Inlay, Onlay, Bridge, Crown
