A cervical intervertebral prosthesis includes lower and upper anchoring plates with a prosthesis core arranged between them to create an articulated connection. The anchoring plates are designed to bear with their anchoring plate surfaces on adjacent vertebral bodies. At least one anchoring plate surface has a rib-like projection thereon which can be used to engage in the vertebral body with a form fit.
