The invention relates to a dental prosthesis system incorporating a superstructure (4, 5), a positioning device, and fixtures (1) that are implantable in a person's jawbone. Each fixture (1) is anchored in the jawbone and its opposite end is arranged so that it will be possible to attach a superstructure (4, 5) to it. By means of the positioning device, fixtures (1) are implanted at definite positions and in definite directions, usually parallel directions. The superstructure includes prefabricated elements with fastening devices (8, 9) that can be attached to fixtures (1). In accordance with the invention, reference device (1a) is designed to put the positioning device in place in such a way as to reliably provide the aforesaid definite positions and directions, therewith facilitating the use of prefabricated superstructures. Through its other aspects, the invention relates to significant components suitable for a dental prosthesis system of this type. Moreover, the invention relates to methods used in connection with the application of the dental prosthesis system. |
