TruZir High Strength

TruZir High Strength is a strong zirconia. The blank goes under cold isostatic pressure process; therefore, it is more homogeneous then uniaxial pressed zirconia, and the shrinkage factor is even throughout the blank. TruZir High Strength zirconia blanks have high strength, excellent biocompatibility and great aesthetics. High Strength (HS) blocks are available in Size: 10, 12, 14, 16, 18, 20, 22, 25mm
