A prosthesis system for replacing two or more adjacent teeth comprises prefabricated elements for fixing to the lower or upper jaw of a patient. The prefabricated elements include an arcuate bridge base (2), two or more substantially rotationally symmetric spacer elements (3), and, for each spacer element, a respective fixture or screw implantable in the jawbone. The system further includes an arcuate dental bridge (4) comprising teeth (6), and an arcuate profile element (41) supporting the teeth (6). On its underside the profile element (41) has a groove or channel to receive the bridge base (2). Each implantable fixture or screw has a screw-threaded bore extending from its outer end for reception of a corresponding screw-threaded shank at one end of the respective spacer element. The bridge base has bores therein to receive fitting portions of the spacer elements and the bridge base is secured to the spacer elements by adhesive and/or by securing screws or nuts. Screws extending through transverse bores in the base and the side walls of the profile element secure the dental bridge to the bridge base. The prosthesis is provided with damping means between the bridge and the bridge base.
