ABSTRACT:
A flush cutter of wires located on a patient's teeth has at least one pivotably carried cutting edge. An outer surface of the edge can be positioned adjacent to a surface from which the wire protrudes. An elastic insert or clamp, for griping cut wire ends, is carried adjacent to the edge. The insert has first and second spaced apart ends. A rigid surface is located to pivot toward the edge. The elastic clamp extends, in part, to the inner surface of the edge. As the cutting edge moves toward the rigid surface to cut the wire, the elastic clamp grips the cutoff wire end for removal. The rigid surface can be formed as a second cutting edge that moves toward the one cutting edge.
