The present invention relates to a combination of a dentalimplant and an insertion tool for inserting the dentalimplant into a bone of a patient. The dental implantcomprises an anti-rotation means having a non-circularcross-sectional contour which comprises at least oneplanar force transmission surface in the form of an anti-rotationsurface (7a, 7b, 7c, 7d) . The insertion toolcomprises an anti-rotation means having a non-circularcross-sectional contour which comprises at least oneplanar force transmission surface in the form of a torquetransmission surface (11a', 11a" ； 11b', 11b''； 11c',11c''； 11d', 11d''). One of said anti-rotation meansforms a recess (6), and the other of said anti-rotationmeans forms a bolt (10) having a rotational axis anddesigned to be received in the direction of the rotationalaxis in the recess (6) , such that the at least one anti-rotationsurface and at least one torque transmissionsurface can cooperate to transmit torque between theparts. The invention is characterized in that the anti-rotationsurface (7a, 7b, 7c, 7d) and the torquetransmission surface (11a', 11a '； 11b', 11b''； 11c',11c'' ； 11d' , 11d'') are arranged such that, while the bolt(10) is received in the recess (6), said anti-rotationsurface (7a, 7b, 7c, 7d) and said torque transmissionsurface (11a',11a''； 11b', 11b''； 11c', 11c''； 11d',11d'') can be rotated relative to one another between afirst, non-torque transmission position, in which saidanti-rotation surface (7a, 7b, 7c, 7d) and said torquetransmission surface (11a', 11a''； 11b', 11b''； 11c',11c "； 11d', 11d'') have little or no contact, and asecond, torque transmission position, in which said anti-rotation surface (7a, 7b, 7c, 7d) and said torquetransmission surface (11a', 11a '； 11b', 11b''； 11c',11c '； 11d', 11d'') are in maximum contact with eachother, wherein the angle between the anti-rotation surface(7a, 7b, 7c, 7d) and the torq
