Rezumat:

In this paper the electrochemical behavior of the titanium and Ti-6Al7Nb in artificial saliva ( Tani&Zucchi and Carter-Brugirard)ion release tests and in vitro biocompatibility of human osteoblasts were studied.The total quantity of ions released in the artificil saliva and corrosion rates are very low,proving a very good corrosion resistance and very low toxicity. The in vitro citotoxicity of Ti-6Al-7Nb alloy was evaluated on the basis of cell morphology and cell viability, and the obtained results revealed high biocompatibility.
