High Strength HT Zirconium Blocks


Product Description

High Strength Zirconia Dental Material HT Zirconia Disc For Open Cad Cam System

 

Product Description
 

 

  • Our Zirconia block is made from zirconia ceramic powder by cold isostatic pressing and machining. It is more homogeneous than uniaxial pressed with high strength, excellent biocompatibility and aesthetics. Labs and Clinics confidently create very strong and precise full-arch restorations.
  • pre-stained zirconia block, which can be directly sintered without staining, are available for extremely economic and efficient results.
    • High Strength zirconia block is used for copings or in restorations.
    • High translucent zirconia block is used for copings or in restorations.
    • Super translucent zirconia block is used for full solid zirconia crowns or copings in aesthetic zone.
    • Ultra translucent zirconia block is used for the latest anterior solid and also for the posteriors.

Zirconia Features

Zirconium dioxide porcelain tooth is a mineral that exists in nature as oblique zircon. Its density and strength are very high, the strength is 1.5 times higher than that of EMPRESS II, more than 60% higher than INCERAM zirconia, combined with unique crack resistance and strong curing performance after cracking, it can make porcelain bridges of more than 6 units. The problem that all all-ceramic systems cannot be used as long bridges is solved.

 

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.
