<p>A connecting element (1) between a bridge (2) and a dental prosthesis comprises a double joint part (6). One end of said part is a spherical head (3) which forms the first joint and the other end forms the first joint and the other end forms the second joint and flares into a cone (7) which tapers toward the flat inner face of the joint cap (9). The joint cap serves as a prosthesis housing to which the dental prosthesis is fastened. The spherical head (3) can be removably inserted with a frictional fit in a suitably dimensioned bore (5) in the bridge. Use of the double joint ensures efficient and uniform distribution of pressure on the bridge(s) during chewing. The dental prosthesis is therefore held more securely and the stress on the anchorages is reduced.</p> |
