Method of laser structuring of the surface of titanium dental implants

摘要

FIELD: medicine; technological processes.SUBSTANCE: invention relates to a method for laser structuring of a surface of titanium dental implants. Due to laser structuring of implant surface, consisting in successive exposure to laser radiation on all parts of implant surface with radiation power density of 630 MW/cm, wherein the impact on the implant cylindrical parts is performed with simultaneous rotation of the implant at a linear speed of 5 mm/s, and on the flat parts of the implant surface with pitch of 2 mcm, wherein to create each next micro-groove on all parts of the implant surface scanning is carried out with pitch of 30 mcm.EFFECT: disclosed method provides a microstructure with nano-roughness on the surface of the implant, which improves the biocompatibility, corrosion resistance and bactericidal properties of the implant.1 cl, 4 dwg
