METHOD FOR MAKING ENDOSSEOUS CARBON-COATED DENTAL IMPLANT Russian patent published in 2015 - IPC A61L27/06 A61L27/08 A61C8/00 B82Y5/00 

FIELD: medicine.

SUBSTANCE: method for making an endosseous carbon-nanocoated dental implant involves processing an implant surface with argon ions accelerated to 1 keV at a pressure of (2-6)·10^-2 Pa with supplying a negative offset voltage onto a carrier to be increased from 800 to 1,500 V for at least 1 hour; multilayer coating of two alternating layers in the total number of 20-30 is sprayed onto the implant base; a thickness of each layer is 50-100 nm; a carbon nanocoating of a thickness up to 1 mcm is sprayed onto the above coating. The first layer of the multilayer coating consisting of compounds of titanium and carbon is sprayed together with arc spraying of a titanium cathode and pulse-arc spraying of a graphite cathode with increasing carbon concentration in each following layer to the overall increase in the concentration in these layers from 14 to 75 wt %; the second layer consisting of solid amorphous diamond-like carbon having a hardness of 70-100 GPa is applied by pulse-arc spraying of the graphite cathode in the environment of diamond-like film condensation at a temperature of no more than 150°C and a carbon ion power of no more than 100 eV.

EFFECT: using the method enables producing the implant having high mechanical and chemical coating stability, as well as biocompatibility and antibacterial properties.
