Cohesive resistance of the primer with various additives and Ni - Cr alloy upon cermet tooth crown

The influence of tin oxide and calcium phosphate additives on the adhesion strength of the material for the manufacture of the ground layer of the artificial tooth and the metal of the crown is considered. An alternative express method for determining the adhesion strength of metal and ceramics using the "Micro Scratch Tester" device was used using the method of drawing a line with a diamond indenter over the finished coating. It was found that the best adhesion is provided by the addition of hydroxyapatite. Tab. 2, ill. 2, bibliography: 3 titles.
