Disclosed is a dental implant fixture. The dental implant fixture includes a body formed with a collar having a predetermined length in an upper end region thereof and a thread part helically formed on an outer surface of the body, the thread part including a broad pitch thread part formed along a lengthwise direction of the body from an implantation end part and a narrow pitch thread part formed from an end of the broad pitch thread part to a collar region of the body and having a pitch narrower than a pitch of the broad pitch thread part. With this, there is provided a dental implant fixture which can provide excellent initial stability while minimizing the bone stress by shortening the implantation time.本發明揭露一種植牙固定裝置。該植牙固定裝置包含:一本體,於其一上端區域中形成具有一預定長度之一領(collar);以及一螺紋部,成螺旋形地形成於該本體之一外表面上。該螺紋部包含:一寬節距螺紋部,係自一植入端部沿該本體之一長度方向形成;以及一窄節距螺紋部,係形成自該寬節距螺紋部之一端至該本體之一領區域,並具有一節距,該節距窄於該寬節距螺紋部之一節距。藉此,提供一種可提供優異之初始穩定性並同時藉由縮短植入時間而最小化骨應力之植牙固定裝置。100...固定裝置120...本體121...斜角部122...領123...扭轉切刃部130...螺紋部131...寬節距螺紋部131’...最頂端寬節距螺紋部133...窄節距螺紋部133’...最底端窄節距螺紋部150...支座耦合部P1...節距P2...節距
