METHOD FOR FORMING SILVER-CONTAINING BIOCOMPATIBLE COATING ON TITANIUM IMPLANTS Russian patent published in 2018 - IPC A61L27/30 A61L27/06 A61K33/38 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely orthopedic dentistry and traumatology, and can be used to form a silver-containing biocompatible coating on titanium implants. For this purpose, a coating is prepared by preliminary machining of the titanium base, surface cleaning, chemical degreasing, the plasma spraying process of the coating followed by the implantation of silver ions (Ag⁺). After degreasing, the polished surface of the titanium base is first treated with a helium ion beam with the introduction of helium ions into the titanium base and the formation of a porous structure on the surface of the implant, the introduction of helium ions (He⁺) is carried out with an energy of 100–200 keV and a dose of 6⋅10¹⁷–6⋅10¹⁸ ion/cm², then the formed porous structure is treated with a silver ion beam (Ag⁺) in a vacuum environment of carbon dioxide (CO₂) with the introduction of silver ions (Ag⁺) into the formed porous surface structure of titanium to form a carbon silver-containing diamond-like non-porous film with antimicrobial properties, while the implantation of silver ions is carried out at an energy of 100–150 keV and the radiation dose (1–4)⋅10¹⁷ ion/cm².

EFFECT: invention provides an increase in the osseointegration properties of the intraosseous titanium implants by creating a silver-containing biocompatible coating with antimicrobial properties.
