Zirconia Ceramic Dental is made of 3%mol Yttria partially stabilized zirconia(Y-TZP), They create an extremely natural-looking appearance. The tooth-colored ceramic material is translucent, like the enamel of your natural teeth, and size and shade can be carefully matched to complement the rest of your smile. Presintered blocks for Dental Ceramic are easy to grind and are distinguished by a high strength and excellent fracture toughness. For this reason the material is not only suitable for molar crowns, but can also be used for manufacturing metal-free posterior bridge substructures.
