Summary: The materials used recently in dental implantology are exclusively made of titanium alloy. This is
reflected in a difficult processing of the material.
Preparation and economic point of view are also very demanding. Our aim was to find a material with high physicomechanical
and biological properties. Our selection was an alloy of chromium and cobalt that exhibited better
physical properties than titanium alloy. Biological properties were maintained by a layering of titanium nitride
and zirconium nitride on the cromium-cobalt alloy. The material with surface – layered structure was biologically
tested. The first test was a cell growth test. The study is a part of the project No. 7356-3 provided by IGA grant
of the Czech Ministry of Health.
