| Summary: | Metallic biomaterials, which are mainly used for the damaged hard tissue
replacements, are materials with high strength, excellent toughness and good
wear resistance. The disadvantages of metals as implant materials are their
susceptibility to corrosion, the elastic modulus mismatch between metals and
human hard tissues, relatively high density and metallic ion release which
can cause serious health problems. The aim of this study was to examine
metallic ion release from Co-Cr-Mo alloy in artificial saliva. In that
purpose, alloy samples were immersed into artificial saliva with different pH
values (4.0, 5.5 and 7.5). After a certain immersion period (1, 3 and 6
weeks) the concentrations of released ions were determined using Inductively
Coupled Plasma - Mass Spectrophotometer (ICP-MS). The research findings were
used in order to define the dependence between the concentration of released
metallic ions, artificial saliva pH values and immersion time. The determined
released metallic ions concentrations were compared with literature data in
order to describe and better understand the phenomenon of metallic ion
release from the biocompatible cobalt-based alloy. [Projekat Ministarstva
