Abstract: A method of making dental prosthesis in which an occlusion model representing a jaw impression obtained with the existing prosthesis is prepared, a guideline is marked a short distance from the edge of the prosthesis. A thin layer of adhesive is applied to the penciled guideline on the occlusion model to fasten a wax wire along the penciled guideline and both ends of the wire fused together. The dental prosthesis is ground to a volume at which the wax wire, when it is placed on the occlusion model, will be completely unencumbered with respect to the prosthesis. The edge of the prosthesis is refilled with a mass of plastic until the wax wire is completely embedded in it and the freshly applied mass of plastic polymerized. The prosthesis, which has been removed from the occlusion model is worked and the wax wire baked or evaporated out of it.
