Abstract: Methods for the manufacture and repair of dental appliance prostheses are provided comprising providing a shaped metallic underlayment, and plating onto at least a portion of the underlayment a layer of a second metallic species. An amount sufficient substantially to obscure the layer, of a polymerizable opaqueing agent is then applied to the layer. Following polymerization of the opaqueing agent through application of heat or radiant energy, especially visible light, the layer is ideally suited for the application of dental aesthetic veneers or other surfacing materials. In accordance with the preferred embodiment, an adhesion promotion species is employed either in a separate treating step for the second metallic layer or through inclusion thereof in the opaqueing agent.
