Dental Materials, Manufacture/Repair, Zirconia
Definition : Dental restorative materials in which the main component is zirconia oxide. The composition is usually yttria tetragonal zirconia polycrystal (Y-TZP) material where Yttria (Y20 a) is an oxide of the metallic element yttrium. Both fully sintered (using hot or cold isostatic pressing) and partially sintered zirconia products (typically blocks and discs) are available as dental materials. Zirconia is used to manufacture crowns, bridges, onlays, inlays, and other dental restorations; the restorations are usually shaped using computer aided design/computer aided manufacturing procedures.
