[Study of Co-Cr-Mo alloys in metal-ceramics].
The new interest of dental workers in Co-Cr-Mo alloys has increased because of the potential risk of nickel-related allergic responses and berylium-related toxic effects. The aim of the present study was to assess the transverse bond strength, rigidity modulus and compatibility of ceramics in four selected Co-Cr-Mo alloys. The obtained results indicate that oxide formation was not easily controlled and that additional sand-blasting was necessary after oxidation of the metal. The bond strength and rigidity modulus were the highest in the alloy containing titanium. Thermal shock tests confirmed the results of mechanical testing.
