The pad possible support part (2) and you attach to this support part in the jawbone and facilities are done and install the alternative tooth component and the structure above upper deck part which is possible (4) you have, especially guaranteeing the high mechanical stability where the structure above upper deck part (4) has, the contact pin which formed just (8) as for the said contact pin on other hand especially makes the appropriate index of in plant simply and securely possible possible (2) the formation notch which is provided in the support part (10) to with fit connection the dentistry in plant which is the pad in (1), with another side, confronts twisting even with when total height is small held downIt does. According to this invention, the contact pin which formed just in the structure above upper deck part (8) section and the support part (2), the said contact pin (8) the formation notch which is imbedded (10) section, it possesses the plural main directions where radius takes the respective relative maximum respectively because of that, the outer part contour of section by some optional straight line to be many also is crossed in two points, every point has simply one tangential line.顎骨に埋込可能な支柱部分(2)と、この支柱部分に付設され代替歯部材を取り付け可能である上部構造部分(4)とを備え、上部構造部分(4)は一体成形された接触ピン(8)を有し、該接触ピンは支柱部分(2)に設けられた成形切欠き(10)へ嵌合結合により埋込可能である歯科インプラント(1)において、一方では特に簡単かつ確実にインプラントの適切な指標を可能にし、他方では、全高が小さく抑えられている場合でもねじりに対する特に高い機械的安定性を保証する。そのために本発明によれば、上部構造部分に一体成形された接触ピン(8)の断面と、支柱部分(2)の、該接触ピン(8)が埋め込まれる成形切欠き(10)の断面とは、半径がそれぞれ相対的な最大値を取る複数の主方向をそれぞれ有し、断面の外側輪郭は、どの任意の直線によっても多くとも2つの点で交差され、どの点もただ1つの接線を有する。
