The cage was implanted / placed by the surgeon according to the surgical technique when the blades / anchoring plates were inserted, the implant got broken.The bone to be treated was extremely firm.Also the 2nd implant used could not be final anchored, since the anchoring plate did not sink into the cage; a stronger striking of the anchoring plate could have caused a renewed implant fracture.
