Vsmile ST Pre-Shaded Zirconia Disc is a series of 16 pre-shaded zirconia blanks that accurate match with all of the VITA Classical shades, with no color-dipping or staining required. This glaze-and-go system eliminates the dipping and staining stages to greatly increase repeatability, improve turnaround time and lower labor costs.
Vsmile ST Pre-Shaded Zirconia Disc is used for the production of full-contour zirconia crowns, bridges and implant crowns.

What factors are related to the light transmittance and strength of zirconia on the material? Generally speaking, the transparency of zirconia has an inverse relationship with its strength. The better the transmittance of zirconia, the lower the strength. 1. Alumina has a certain toughening effect in zirconia, but the higher the alumina content, the greater the impact on transparency. The high content of alumina has good mechanical properties, but the transparency is greatly reduced. 2. The content of stabilizer yttrium oxide is also related to the transparency and strength of zirconia. 3. The particle size and agglomeration size of zirconia powder are also related to transparency and strength.
