FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to orthopaedic dentistry. A method for making an intraosseous dental implant involves sand-blast finish of an implant surface by alimunium oxide particles, plasma-based layer-by-layer deposition of a system of biocompatible coatings containing mixed titanium or titanium hydride or calcium hydroxyapatite powders onto an implant carrier. The first layer consists of titanium or titanium hydride of dispersity 3-5 mcm at spraying distance 70-80 mm and thickness 5-10 mcm. The second layer is titanium or titanium hydride of dispersity 50-100 mcm at spraying distance 100 mm and thickness 50-115 mcm. The third layer represents mixed titanium or titanium hydride of dispersity 40-70 mcm and calcium hydroxyapatite of dispersity 5-10 mcm in ratio 60-80 and 20-40 wt % respectively, at spraying distance 80 mm and layer thickness 15 -20 mcm. The forth layer consists of calcium hydroxyapatite of dispersity 40-70 mcm at spraying distance 70 mm and layer thickness 20-30 mcm. Thereafter, the multilayered system of the biocompatible coatings is covered by a metal film consisting of a ferric triad (iron, cobalt or nickel) of thickness 20-35 nm by magnetron sputtering. A carbon nanocoating of thickness up to 1 mcm is prepared thereon. The carbon nanocoating represents carbon nanotubes and carbon nanofibres of diameter 50-200 nm.

EFFECT: method provides making the implant coated so that to promote the active growth of bone tissue.
