In the experiment conducted biomechanical tests to determine the coupling forces 4 groups of implants with the bone tissue: No. 1 was made of medical steel, No. 2 was made of titanium alloy VT6 with the modified surface by using the method of the thermo-chemical treatment. No. 3 and No. 4 were made of titanium alloy VT6 with composite coating (calcium phosphate + 1% and 5% germanium, respectively), applied by the method of microarc oxidation. Implants were installed in the proximal femur of purebred cats (29 animals). Upon removal of animals from the experiment (after 3 months) conducted static tests. Noted that the bond strength in 3 and 4 groups of implants with the bone tissue is more pronounced than in groups 1 and 2.
