METHOD FOR MAKING INTRAOSSEOUS DENTAL IMPLANT WITH ION-BEAM MODIFICATION OF PLASMA-DEPOSITED MULTILAYER BIOACTIVE COATING Russian patent published in 2012 - IPC A61L27/02 A61C8/00 C23C14/00 C23C14/58 

Abstract RU 2458707 C1

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely orthopaedic dentistry, and may be used in making intraosseous implants by coating their metal substrate with plasma layers to be exposed to ion-beam modification. The presented method for making the intraosseous implant involves sandblasting of the implant surface by aluminium oxide particles, layered by plasma deposition on the implant substrates of the system of biocompatible coatings of various dispersion and thickness consisting of five layers: first two ones of titanium or titanium hydride, the next two layers of mixed titanium or titanium hydride and calcium hydroxyapatite differing by the contents of the components in the layers, and the fifth layer of calcium hydroxyapatite; then the multilayer system of biocompatible coatings is radiated in the vacuum medium of hydrocarbon gas by high-energy ions of inert gas with energy 40-130 keV and a radiation dose of 2000-5000mcKl/cm2.

EFFECT: method provides higher bioactivity and mechanical strength of the implant.
