THE DIFFERENCE BETWEEN ZIRCONIUM CROWNS AND STAINLESS STEEL CROWNS IN THE PROSTHETICS OF PREMOLARS

Abstract

One of the reasons for the refusal to use CAD/CAM technologies in dentistry are reports of the insolvency of all-ceramic frame restorations made of polycrystalline ceramics based on zirconium dioxide and the chipping of veneers [1, 2]. The discrepancy in the recommendations for the manufacture of frame all-ceramic restorations raises a number of questions. Sandblasting is still widely used to improve surface roughness, strengthen the bond between the veneer and the frame and increase the strength of the joint during cementing.
