Implant for intervertebral space

An implant for an intervertebral space comprising:

• a shaped body comprising:
• a top contact surface to be placed on an end plate of the vertebra adjoining the implant from above, a bottom contact surface to be placed on an end plate of the vertebra adjoining the implant from below, wherein the top and bottom contact surfaces are convex;
• two lateral side surfaces having a length greater than their width, a front and a rear surface as well as a central axis that intersects the two contact surfaces, a longitudinal axis that intersects the front and rear surfaces, and a transverse axis that intersects the lateral side surfaces;
• an opening extending along an axis that is parallel to the central axis;
• and
• a central plane defined by the longitudinal axis and the transverse axis and situated between the contact surfaces and at right angles to the central axis of the body,
• wherein the contact surfaces have a plurality of teeth with central axes,
• wherein the central axes of the plurality of teeth are inclined relative to the central plane in such a manner that rotation of the body 90 degrees about the longitudinal axis is facilitated in one direction and impeded in the other direction;
• and
• wherein the maximum distance between the two lateral side surfaces is smaller than the maximum distance between the two contact surfaces.
