Abstract
A limited life span of endoprostheses in the absence of other complications is explained by the aseptic implant instability arising and developing as a result of insufficient osteointegration. The surface of implants made of the VT-6 alloy was treated to form calcium phosphate coatings including those containing germanium (0.4 and 2.5 mass %), for the purpose of carrying out a comparative analysis of the response of an organism. The surface of the resulting coatings was investigated by means of scanning electron microscopy. It was established that the introduction of germanium has a substantial effect on the surface morphology of the coatings. It was shown with the help of the light microscopy of histological sections that osteointegration processes are most intense with the group of implants containing germanium at a level of 2.5 mass % in the calcium phosphate coating.
