Abstract
The paper deals with physical and mechanical properties of ceramic material containing complex oxide solid solution Zr1–n[YbNd]nO2 and corundum microfase, taking into account aesthetic and strength requirements of clinical practice of prosthetic dentistry. It has been shown that the developed ceramic has a static bending strength of 850 MPa and according to the international standard ISO 6872:2015 “Dentistry – Ceramic materials” belongs to the 4th and 5th class of dental ceramic materials. This makes it possible to use it for the manufacture of not only single crowns, but also four-units dentures of any localization and any type of fixation. The developed ceramics meet the requirements of prosthetic dentistry and color characteristics, have high opacity, which makes it possible to mask the color of supporting structures.
