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.
Claims60
A dental instrument for cutting and holding a wire end extending from a surface comprising:
- first and second, opposed cutting edges movable relative to one another and oriented so as to be positionable against a surface from which a wire end extends;
- an elongated elastomeric member with a gripping surface wherein the member is positioned with at least a region of the gripping surface located adjacent to one of the edges whereby as the edges move together the region of the surface of the member moves adjacent to and substantially abuts at least part of the other edge.
An orthodontic cutter comprising:
- first and second pivoted, flush cutting edges;
- an interior recess formed adjacent to one of the edges;
- and
- a deformable wire clamping member substantially carried in the recess.
A dental instrument for cutting and holding a wire end extending from a surface comprising:
- a flush cutting edge movable relative to an opposed rigid surface and oriented so as to be positionable against a surface from which a wire end extends;
- an elastomeric member with a substantially flat gripping surface wherein the member is positioned with at least a region of the flat gripping surface located adjacent to the edge whereby as the edge moves toward the opposed surface, the region of the flat surface also moves toward that surface.
An orthodontic cutter comprising:
- at least one flush cutting edge;
- an interior recess formed adjacent to the edge;
- and
- a deformable wire clamping member substantially carried in the recess.
A replaceable elastomeric insert for a cutter comprising:
- an elongated elastomeric, body having first and second free ends and,
- wherein the body includes a substantially planar, elongated wire clamping region.
