remain for a relatively long period of time even after implanting the implant 100 and function to foster the bone formation the bone growth factors 160 may be provided on the screw blades 130 and also be provided on the outer peripheral surface of the core 110 when the bone growth factors 160 are provided on the core 110 it is possible to prevent the bone growth factors 160 from being peeled off during the implantation process by increasing a diameter of a drill bit to be greater than the diameter of the core 110 including the bone growth factors 160 to implant the implant 100 in the bone structure and the like drill bit holes may be formed in the bone structure in correspondence to the diameter of the core 110 and screw grooves may be formed in the bone using a screw groove forming instrument next the implant 100 may be implanted in the bone structure the bone growth factors 160 may be provided together when the implant 100 is manufactured and may be provided on or injected to the connecting groove 140 before implanting the implant 100 according to the present embodiment the post 122 included in the mounting portion 120 is configured to be mounted with an abutment prosthesis in the shape corresponding to the outer peripheral surface of the mounting portion 120 using a frictional type scheme a frictional typed post may be formed at an angle of 1 u00b0 4 u00b0 and.
