An implant for an intervertebral space with a shaped body. The implant has a top contact surface to be placed on a base plate of a body of the vertebra adjoining the implant from above, a bottom contact surface to be placed on a cover plate of a body of the vertebra adjoining the implant from below, two lateral surfaces, a front lateral and a rear lateral surface as well as a central axis that intersects the two contact surfaces, a longitudinal axis that intersects the front and rear lateral surfaces and a transverse axis that intersects the lateral surfaces. The implant also has a central plane situated between the contact surfaces and at right angles to the central axis of the body. The contact surfaces have a plurality of macroscopic teeth with central axes, where the central axes of the plurality of teeth are inclined relative to the central plane in such a manner, that a rotation of the body of 90° about the longitudinal axis is facilitated in one direction and impeded in the other direction. The distance between the two lateral surfaces is smaller than the distance between the two contact surfaces. |
