An implant (5 ', 6, 7; 9) for insertion into an intervertebral space (62), which has upper and lower support surfaces (73, 74; 63, 64) with a guide groove (11, 12) on each of the upper and lower support surfaces (63, 64), characterized in that one of the guide grooves (11, 12) is formed such that a guide (31), which is insertable or is inserted into a of the guide slots (11, 12), can be held or is held in a non-displaceable manner in two spatial directions due solely to the shape of one of the guide slots (11, 12), the two spatial directions being parallel and normal to the respective support surface, respectively. |
