ABSTRACT:
The hand tool is used as a cosmetic dental trimmer for restorative material of the composite resin type to remove any excess of such material to more perfectly contour the restorative material to match the natural contour of the original tooth surface. The tool includes an elongated handle connected by a tapering shank to the trimming (shaving) blade which has a hard metal layer, such as tunsten carbide, having the property that it will not discolor the composite resin material. The blade is preferably formed, in one embodiment, by a very slightly concaved face defining the blade along an arcuate (concave) edge thereof. Preferably, a pair of tools are used with oppositely arranged blades. Alternate embodiments include a tool having an excavator blade and one constructed as a composite shaver or shaper.
