3mo1% yttrium oxide stabilized tetragonal polycrystalline nano-zirconia (3Y-TZP) is currently the most widely used biomedical material. The characteristics of 3Y-TZP not only lie in its high fracture strength (>1000 MPa), high fracture toughness (>10 MPa·m1/2), and significantly slow down the cracking behavior, but also this colored zirconia ceramic has better Its aesthetics can match the color of human teeth very well.
Compared with traditional dental ceramic materials, tetragonal zirconia (t-ZrO2) polycrystalline ceramics (Y-TZP) with yttrium oxide (Y2O3) as a stabilizer due to the presence of metastable tetragonal zirconia to monoclinic zirconia (m- ZrO2) has a high toughness due to its stress-induced phase transformation toughening effect, and has received widespread attention. Dental nano-zirconia is an excellent high-tech biological material. It is currently recognized in the dental industry that both the price and the quality of dentures are the best dental nano-zirconia.
