ASSESSMENT OF FRACTURE RESISTANCE OF CAD-CAM CERAMIC CROWNS

Abstract

Angular abutments have been developed in the anterior part of the upper and lower jaw to achieve optimal mechanical, aesthetic and biological results in treatment based on implants. The optimal placement of the implant and the design of the suprastructure make it possible to achieve a high aesthetic result. It is known that with an increase in the angle of inclination of the abutment, the microstrain increases significantly, which makes it important to choose the preferred material of the suprastructure. An option for restoring the dentition in case of partial adentia is prosthetics based on implants, which allows preserving the integrity of adjacent teeth.
