Abstract

Arrangement for joining denture components by adhesion, in particular a prosthesis component with an anchoring or bedding part. It consists of a pair of connecting elements or model parts for connecting elements which are joined to or can be joined to the components to be joined and at least one of which encloses the other. So that the join can be closed without the danger of thermal distortion with correctly prepared individual components--if appropriate even in the mouth of the patient--the surfaces to be joined on the connecting elements or the model parts have an intermediate space which allows positioning of the components to be joined and can be filled with sealing compound which hardens, the surfaces comprising surface portions cut away in respect of the direction of loosening and hence acting on the sealing compound in a positive manner. To shape the intermediate space, a particular model part is envisaged, which can be inserted, in identical shape, between a model part for the internal connecting element and a model part for the external connecting element.
