Ceramic designs based on zirconium oxide
Irconium oxide is a new material (metal-free ceramics), which is highly durable, white, very esthetic, biocompatible with the tissues of the oral cavity. Zirconia frame for crowns is made by computer milling, which accounts for precision of manufacturing. Frame strength of zirconium oxide is 600 MPa . First, the frame is made of zirconium oxide (due to tooth color), then the zirconia framework is applied to the ceramic mass.
