The Burdenko hospital began to use an innovative antibacterial coating for implants

Scientists at Tomsk Polytechnic University have developed antibacterial calcium phosphate coatings for titanium intraosseous implants. Modified implants have better biocompatibility and corrosion resistance, as well as shorten the recovery time of bone tissues. The new technology has already begun to be used in clinical practice at the Burdenko hospital, the press service of the university said on August 22, 2023.

According to the developers, the formation of coatings on titanium implants, including 3D-printed ones, is carried out by the method of micro-arc oxidation using a pulse power source. This technique has a number of advantages - it is more economical and environmentally friendly, simple, provides high productivity and allows you to obtain porous calcium-phosphate and oxide coatings with high adhesion strength, as well as accelerating osteintegration.

Antibacterial calcium phosphate coatings for titanium intraosseous implants

As explained by the project manager, associate professor of the Scientific and Educational Center B.P. Weinberg Sergey Tverdokhlebov, for the needs of the hospital it is necessary not just a calcium-phosphate bioactive coating for implants. And implants, on the surface of which a layer is applied that performs the function of targeted delivery of pharmaceuticals, primarily antibiotics. During the experiments, it was the bioactive zinc-containing calcium-phosphate coatings that showed themselves best. So, it was possible to achieve an increase in antibacterial effectiveness, a reduction in the number of bacteria of certain strains, he said.

In fact, now, in cooperation with the largest medical centers, we are forming a domestic market for high-tech medical devices. The results already obtained and further research will improve antibacterial coatings for use in surgical practice even with an increased risk of microbial contamination, the scientist summed up.[1]
