essential information:


Biological nanoscale zirconia powder has a 99.9% market share in the European and American markets of medical bioceramics. It is mainly used in high transparency dentures such as dental crowns, bridges, full crowns, implant roots, abutments, and human joints. Yttrium stabilized zirconia is currently the most widely used biomedical material. The characteristics of yttrium stabilized zirconia used in high transparency dentures not only lie in its high fracture strength (>1000 MPa) and high fracture toughness (>10 MPa · m1/2), significantly slowing down the behavior of slow cracking, but also in the ceramic blocks fired from yttrium stabilized zirconia used in high transparency dentures, which have high transparency, strong jade texture, and high whitening, and can match well with the color of human teeth. And it is extremely suitable for milling using manual grinders or CAD/CAM equipment.


Compared with traditional dental ceramic materials, yttrium stabilized zirconia polycrystalline ceramics (Y-TZP) for high permeability dentures using yttrium oxide (Y2O3) as a stabilizer have received widespread attention due to the stress induced phase transition toughening effect of metastable tetragonal zirconia to monoclinic zirconia (m-ZrO2), which leads to higher toughness. High transparency yttrium stabilized zirconia for dentures is an excellent high-tech biomaterial, and it is currently recognized in the dental industry that both price and quality are better for denture production than high transparency yttrium stabilized zirconia.
