Russian scientists have developed 3D implants with an antibacterial biocoating based on zinc, silver and calcium phosphate. The structures have an individual configuration, safely interact with bone tissue and contribute to its regeneration, the press service of the Novosibirsk Research Institute of Traumatology and Orthopedics (NIITO) named after N.N. Ya. L. Tsivyana.

"3D implants obtained by additive technologies with antibacterial bio-coating based on zinc, silver and calcium phosphate <…> have not only an individual configuration, but a number of preventive properties, including including antibacterial ones - due to special coatings," the press service said.

Employees of the Novosibirsk NIITO im. Ya. L. Tsivyan, Research Center for Fundamental and Translational Medicine and the Institute of Strength Physics and Materials Science, Siberian Branch of the Russian Academy of Sciences (Tomsk).

As the authors of the study explain, the creation of porous three-dimensional materials to compensate for bone defects and its subsequent regeneration is an important direction materials science.

"We revealed the preservation of the viability of culture cells, which allows us to conclude that the product and its components do not negatively affect the rate of cellular respiration, which ensures the preservation of cell viability for 48 hours," the press service quotes the words Irina Kirilova.

According to the press service, such structures are necessary for complex clinical cases, including revision surgery of the joints. The scientific article "3D-implants obtained by additive technologies with antibacterial bio-coating based on zinc, silver and calcium phosphate" was published in the journal Materials Characterization (USA).
