The present invention relates to a combination of a dental implant and an insertion tool for inserting the dental implant into a bone of a patient. The dental implant comprises an anti-rotation means having a non-circular cross-sectional contour which comprises at least one planar force transmission surface in the form of an anti-rotation surface (7a, 7b, 7c, 7d). The insertion tool comprises an anti-rotation means having a non-circular cross-sectional contour which comprises at least one planar force transmission surface in the form of a torque transmission surface (11a', 11a"； 11b', 11b"； 11c', 11c"； 11d', 11d").
