Ceramic Materials Based on a Complex Oxide Solid Solution of a Tetragonal Form of Zirconia: Application in Prosthetic Dentistry

We explored the physical and mechanical properties of ceramic material containing complex oxide solid Zr1- n[YbNd]nO2 solution and corundum micro phase and its potential use in prosthetic dentistry practice meeting aesthetic and strength requirements. The ceramic obtained is shown to have a static bending strength of 850 MPa. According to the international standard ISO 6872: 2015, "Dentistry-Ceramic Materials," the materials belong to the fourth and fifth class. This makes it possible to apply the material not only for making single crowns but also to manufacture four-unit bridgework having no localization and fixing restrictions. The new ceramics meet the requirements set forth in prosthetic dentistry and feature required color characteristics and has high opacity which makes it possible to mask the supporting structures.
