The invention relates to an intervertebral implant comprising at least two mounting surfaces (10, 10'), facing away from each other, for mounting on facing vertebral body surfaces (30, 30') of two adjacent vertebrae (3, 3'), a distance between the two mounting surfaces (10, 10') being modifiable by means of an expansion device arranged between the mounting surfaces (10, 10') and comprising at least one actuating element (12), the expansion device comprising at least two pivotable lever elements (14, 15) which are connected to each other by means of a rotational shaft (13) in a scissor-type manner, at least one widening component (16, 16') which is designed to open up the lever elements (14, 15), and at least one securing element (17), the securing element (17) being designed to fix the minimum widening of the lever elements (14, 15). The structure of the intervertebral implant (1) provides a high load-bearing capacity and a high level of strength development in addition to a sufficiently large total height adjustment during the expansion thereof. Furthermore, a lordosis angle can be adjusted.
