Description In recent dental implantology, technically pure titanium or its alloys are broadly used as common metal material. The material possesses optimal biological characteristics. Unfortunately, its technological processing is difficult and limiting for production of some types of dental implants. Subperiostal implants might be pointed out in this respect. The objective of research project was to substitute titanium and titanium alloys for well-processed chromium cobalt alloy coated with TiN, ceramic material ZrN or multilayered Zr/ZrN. Other objective was to prove its biocompatibility, full adhesivity and mechanical resistance. Results indicated high chemical resistance, of the material that, thanks to coating, reduced ion relase from chromium cobalt alloy by 28-32 % in relation to surface roughness. Such results are very promising for dental implantology. The study presented in this paper was supported by project No. 7356-3 provided by the IGA MZ ČR ND grant agency. The research was carried out within the frame of Stomatological Research Center (SVC).
