NOVELTY - An implant with bionic bone unit structure comprises a bone-like unit concentric circle formed by grooves at an equal interval of 10-30 µm and a depth of 5-10 µm as root (3) of the implant, the maximum radius of the concentric circle is 80-120 µm, the intersection angle of side wall of the groove with a minimum radius of 15-50 µm and the implant bone inner surface is 45-90°, the concentric circle is provided with 100-1000 nm thick titanium coating. The bionic bone unit topography at the root of the implant promotes the osseointegration of the implant. USE - The implant with bionic bone unit structure is used for promoting osteogenesis and inhibiting osteoclast. ADVANTAGE - The bionic bone unit structure of the root of the implant promotes the osseointegration of the implant bone, creatively patterns the implant surface into bionic bone unit shape which induces stem cells to grow along the concentric circle structure through the curved microenvironment and promotes the osteogenic differentiation of stem cells. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of implant structure. 1Base pile 2Neck 3Root
