As the authors of the development note, in the postoperative period after arthroplasty, i.e. joint replacements, there is always a risk of complications from antibiotic-resistant bacteria such as Staphylococcus aureus and Escherichia coli. This has been a medical and socioeconomic problem for a long time. Scientists from all over the world are trying to create biocompatible and antibacterial coatings that provide postoperative bacterial safety.
Russian scientists have succeeded in synthesizing a material for the protection of implants based on titanium oxide with the addition of calcium, phosphorus, silicon and boron by the method of arc oxidation, which makes it possible to increase the bioactivity of the material. And then particles of copper and silver were introduced into it by the method of ion implantation.
According to the developers, this coating will be in demand due to medical necessity and can be used in implantology and maxillofacial surgery.
“The relevance of the development is explained by the increasing demand for endoprosthetics of bone implants associated with an aging population and a wider spread of degenerative diseases. Titanium and its alloys are by far the most widely used materials for replacing damaged areas of bone tissue, ”said Anastasia Popova, one of the co-authors of the study, a second-year student of the iPhD Biomaterial Science program at NUST MISIS.
