This work presents the results of a comparative in vitro study into the biocompatibility of titanium samples, the surface of which was pre-treated using various methods: milling, machining with acid etching and irradiation with a powerful ion beam (PIB) for creating a relief with the required roughness and the shape of asperities. A study of the effectiveness of attachment and growth of Balb/NIH 3T3 fi broblasts on titanium products with various types of surface treatment demonstrated that irradiation of a titanium surface with a powerful ion beam (PIB) leads to its active colonization with cells having a fl attened and stellate shape, which confi rms their active growth. An assessment of migration of metal impurities from the titanium alloy VT 1-0 was evaluated using the x-ray fl uorescence method
