An implant is intended to be inserted into an intervertebral space and more specifically between two cervical vertebrae or also into a lumbar space, following body measurement adaptations. This component comprises, on the inside, an assembly comprising a protective and reinforcing shield made of a tough material with, in the continuation thereat, a ball which acts as a load-spreading centre. In order to adapt to suit the morphology of the receiving site, the implant is a soft polymer monobloc sized to suit the intervertebral space with a concave posterior end and an anterior end that is flat with rounded corners made of a preferably slightly soft polymer such as silicone or any other material that is similar but able to withstand compression. The upper and lower faces are reinforced by a yoke of greater density and are covered with an osteoconduclion or osteoinduction agent. The exterior periphery of the component is enclosed in a strip of polyester embedded into the surface of the constituent material. Four X-ray markers are included in this component, two of them vertical and two horizontal. Attached to the anterior part is a plate of soft elastomer internally reinforted by a polyester web perforated with holes for vertebral attachment.
