ST Preshade Dental Zirconia Block Yucera Dental Lab Materials CAD
CAM
CAD CAM Dental Zirconia Blank
Advantages :
- Top raw material from Tosoh in Japan
- 16 A-D shades available;
- High translucency(41% total light transmittance)
- High flexural strength
- accurate, even and stable color;
- No hand coloring needed
CAD CAM Dental Zirconia Blank 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.
CAD CAM Dental Zirconia Blank Feature
high flexural strength, fracture resistance, exceptional
durability, and easy milling properties with precision. Pre-shaded
zirconia disc consisting of three pre-colored layers Easy Handling:
Polish or Glaze after Sintering Ideal for full contour crowns and
bridges
CAD CAM Dental Zirconia Blank Introduction
