Dental zirconia 1 article

Dental zirconia is a polycrystalline ceramic used for milled crowns, bridges, implant components and other indirect restorations. Dental grades are commonly based on yttria-stabilized zirconium oxide and are shaped through CAD/CAM manufacturing before final sintering or finishing according to the system. Unlike silica-rich glass ceramics, zirconia is not conventionally etched with hydrofluoric acid for bonding, so surface preparation and cementation follow a different material logic from feldspathic porcelain or lithium disilicate.
