METHOD FOR MODIFYING TITANIUM IMPLANT SURFACES WITH BIOCERAMIC POWDERS

摘要

FIELD: medicine.SUBSTANCE: titanium implant surface is thermally treated with an argon-plasma jet with arc current 150-250 A, length 2.5-3.0 min at a treatment distance of 80-120 mm followed by thermally activated surface blasting with a bioceramic powder having particle size 150-500 mcm at jet pressure 0.6-0.7 MPa for 10-15 sec.EFFECT: method is technologically simple, enables modifying the titanium implant surface with bioceramic particles and provides creating the high-effective osteointegration surface structure of implants.2 cl, 2 ex
