An insert for a dental prosthesis screwed onto an implant, in particular of the type comprising a superstructure (2) and an implant (3) integrated in the bone (4), which are reciprocally joined by means of a screw (5, 25). The insert of the invention consists, in particular, of an element made of a damping material interposed between the coupling surface (6, 7) of the superstructure (2) and implant (3). Thanks to the insert of the invention, a dental prosthesis screwed onto an implant is obtained, which reproduces the natural anchoring state of the tooth to the bone, so that the stress peaks on the superstructure are damped before being discharged onto the implant and consequently also onto the bone. The insert of the invention also offers the advantage of sealing the contact area between the superstructure and the implant, thus preventing dangerous bacterial infiltrations. |
