To provide an internal connection dental implant that allows a smaller diameter implants. An internal bore 66 provided in a portion of the body has a proximal end and a distal end 72 to the open proximal end of said body, first portion 68 of the inner lumen with an inclined surface 80 facing the interior have. Path the inclined surface, which extends toward the vicinity base end of the inner lumen to the distal end of said inner lumen, and is inclined inwardly toward the distal end with respect to said longitudinal axis when viewed implant from the side it is formed with a. Having the second portion of the inner lumen with a driving region 69 inside faces that are disposed between the distal end of the distal end and the inner lumen of said surface 80, drive region facing the inside, the interior until in facing inclined surface 80 and has a plurality of recessed projection 74 extending partially. Also, with the third portion of the inner lumen with a female threaded area 70 that is disposed between the distal end of the inner lumen and the drive region. .BACKGROUND 8【課題】小さなインプラント直径を可能にする内部連結歯科インプラントを提供する。【解決手段】本体の一部分内に設けられた内部内腔66は前記本体の開口基部端に基部端と末梢端72を持ち、内部に面する傾斜表面80を含む前記内部内腔の第一部分68を持つ。前記傾斜表面は、前記内部内腔の基部端近くから前記内部内腔の末梢端に向けて延び、インプラントを側面から見た時に前記縦軸に対して末梢端に向けて内向きに傾斜する径路を持って形成される。前記表面80の末梢端と前記内部内腔の末梢端との間に配置した内部に面する駆動領域69を含む前記内部内腔の第二部分を持ち、内部に面する駆動領域は、内部に面する傾斜表面80中まで部分的に延びる複数の凹状突出部74を持つ。また駆動領域と前記内部内腔の末梢端との間に配置しためねじ付き領域70を含む前記内部内腔の第三部分を持つ。【選択図】図8
