CAD CAM Open System zirconia blank Full Contour Super High Translucent Denture Zirconia disc

 

CAD CAM Open System zirconia blank Full Contour Super High Translucent Denture Zirconia disc is a high-performance material for digital dental restorations, widely used in the production of all-ceramic crowns, bridges and other restorations.

Raw materials:

High-purity zirconium oxide (ZrO₂): Using nano-level high-purity zirconium oxide powder, through precise powder ratio and sintering process, to ensure the density and uniformity of the material.

Components
ZrO2+HfO2+Y2O3	≥99%
Y2O3	≤6.0%
Al2O3	<0.5%
Other Oxides	<0.5%

Sintering temperature:
The recommended sintering temperature is 1,500°C to ensure the best performance and stability of the material.
Advantages:

High-strength performance:
The use of high-purity zirconium oxide powder and advanced sintering process gives the material excellent bending strength, ensuring the long-term stability and durability of the restoration in the mouth.
Excellent light transmittance:
Through precise control of grain size and sintering process, high light transmittance is achieved, simulating the aesthetic effect of natural teeth and improving patient satisfaction.
Good biocompatibility:
No adverse reaction with oral tissues, ensuring the oral health of patients.
Strong processing adaptability:
Compatible with various CAD/CAM systems, convenient for precise processing, shortening production cycle and improving work efficiency.
