This creation is a kind of autograft,It includes an implant and an at least shim,Implant system include a rod piece,One thread segment and a Bottom of Thread,What rod piece outer surface is arranged in thread segment spiral,Bottom of Thread forms a spiral reference line,Shim sets what Bottom of Thread,Each shim includes a blade part and a filling perforation portion,Blade part sets what Bottom of Thread and has a cutting face,Cutting face position what blade part is simultaneously tilted along the direction of spiral reference line towards rod piece bottom end,Cutting face and Bottom of Thread press from both sides acute angle,Filling perforation position what Bottom of Thread and neighbouring cutting face,This creation autograft generates autologous bone bits by thread segment and blade part cutting bone,By cutting face backstop and collection autologous bone bits to be filled into filling perforation portion,Gu Ge More conjunction is accelerated to shorten the bone restoration time.本創作係一種自體植入物，其包含一植體及至少一填補單元，植體係包含一桿件、一螺紋段及一螺紋牙底，螺紋段螺旋設置於桿件外表面，螺紋牙底形成一螺旋基準線，填補單元設於螺紋牙底，每一填補單元包含一刀刃件及一填孔部，刀刃件設於螺紋牙底並具一切削面，切削面位於刀刃件並沿螺旋基準線的方向朝向桿件底端傾斜，切削面與螺紋牙底夾銳角，填孔部位於螺紋牙底並鄰近切削面，本創作自體植入物藉由螺紋段及刀刃件切削骨骼產生自體骨屑，由切削面止擋及收集自體骨屑以填充進填孔部，加速骨骼癒合減短骨頭復原時間。
