<p>A dental filing tool having a handle easy to hold between fingers which arches over and secures at both ends of a thin filing strip coated with some superfine abrasive material, especially but not limited to diamond dust, or alternatively a sharp cutting system along the edge or lateral surface. From hole-like openings with slots at each end, the strip is fastened between each end of the handle with sufficient tension in the strip to create a rigid filing and grinding surface. The handle is made from formable materials not limited but like plastics injected into mold with which a filing strip is inserted. On the outside edge of each vertical arm of the handle is a smooth flatten surface where to place fingers to hold the handle. The dental filing tool is disposable when the abrasive material of the filing strip wears off.</p> |
