Product Description
Lithium Disilicate Blanks
The cad cam blanks are compatible with the Sirona Cerec milling system, it has LT and HT translucency, and sizes of B14 and C14.
Strength: The minimum biaxial flexural strength of the lithium disilicate block for all-ceramic dentures after complete crystallization is 300MPa.
Lithium disilicate blank features as followings:
- Superior aesthetic and transparency
- Aesthetics and hardness simulating natural tooth (reducing the excessive wear of the opposing teeth and surrounding restorations
- High chemical stability and mechanical strength
- nano micron crystallization provides better edge stability and structural accuracy for milling
- The simple and rapid crystallization process reduces operating time
- Shade: Vita Class Shades, Plus bleaches BL1, BL2,BL3,BL4.
- with a shrinkage ratio close to zero, facilitates the efficient design and digital processing
- Package: 5pcs/box.
