Claim 0:
1. A dental implant set comprising:
a fixture for insertion into a bore hole arranged in bone tissue having first indexing means,
a dental component having second indexing means and being adaptable to the fixture in an engaged position where the first indexing means and second indexing means mate and in an intermediate position where the dental component and the fixture are in contact with each other but the first indexing means and the second indexing means do not mate, and
a fixation screw being adapted for fixating the dental component to the fixture,
wherein in the intermediate position:
a first contacting surface of the fixation screw is arranged to abut a second contacting surface of the dental component and a third contacting surface of the dental component is arranged to abut a fourth contacting surface of the fixture, and

wherein the dental implant set is arranged such that the maximum capacity to transmit torque is greater between the first contacting surface and second contacting surface than between the third contacting surface and fourth contacting surface, so that when the fixation screw is subject to a torque and an axial force applied by a user, the dental component will rotate with the fixation screw,
wherein the first indexing means comprises indexing depressions extending in the radial direction from a first surface of the fixture and the second indexing means comprises indexing projections extending in the radial direction from a second surface of the dental component, and wherein the indexing depressions and projections are distributed along the circumference of the first surface and second surface of the fixture and the dental component respectively, such that the dental component can only mate in certain specific rotational orientations with respect to the fixture, and
wherein the dental component further comprises at least one first indexing projection, and at least two second indexing projections, and wherein the fixture further comprises at least one first indexing depression, and at least two second indexing depressions, wherein the at least one first indexing projection and at least one second indexing projection and the at least one first indexing depression and at least two second indexing depressions are distributed along the circumference of the dental component and the fixture, respectively, in such way that the dental component can only mate in one rotational orientation with respect to the fixture, wherein the at least one first indexing projection is only enabled to mate with the at least one first indexing depression after said at least two second indexing projections have mated with said at least two second indexing depressions.
