instrument, bibeveled cutting

(bī´bevld),
n an instrument in which both sides of the end of the blade are beveled to form the cutting edge, as in a hatchet.

instrument blade,

n the part bearing a cutting edge; it begins at the terminal angle of the shank and ends at the cutting edge.

instrument, blade face,

n the innermost surface of a scaler or curet blade.

instrument, carving,

n See carver.

instrument, classification of, names,

n the classification of instruments by name to denote purpose (e.g., excavator), to denote position or manner of use (e.g., hand condenser), to describe the form of the point (e.g., hatchet), or to describe the angle of the blade in relation to the handle.

instrument, condensing,

n a handheld device used to adapt dental amalgams to a prepared cavity.

instrument, cutting,

n an instrument used to cut, cleave, or plane the walls of a cavity preparation; the blade ends in a sharp, beveled edge. Unless otherwise specified, it refers to a hand instrument rather than to a rotary type.

instrument, diamond,

n a rotary abrasive instrument, wheel, or mounted point. Made of fine diamond chips bonded into a desired form; used to reduce tooth structure.

instrument, double-ended,

n a hand-held tool with two functional ends that are identical or complementary.

instrument, double-plane,

n an instrument with the curve of the blade in a plane perpendicular to that of the angles of the shank.

instrument, formula name of,

n a method of naming and describing dental hand instruments. Measurements are in the metric system. The working point is described first; then the formula is given, in three (or sometimes four) units. The first figure denotes the width of the blade, in tenths of millimeters; the second shows the length of the blade, in millimeters; and the third indicates the angle of the blade in relation to the shaft, in centigrades or hundredths of a circle. Whenever it is necessary to describe the angle of the cutting edge of a blade with its shaft, the number is entered in brackets as the second number of the formula. Paired instruments are also designated as right or left. In lateral cutting instruments the one used to cut from right to left is termed
right; in direct cutting instruments with right and left bevels, the one having the bevel on the right side of the blade as it is held with the cutting edge down and pointing away from the observer is termed
right.

instrument grasp,

n See grasp, instrument.

instrument, McCall's,

n.pr a periodontal instrument used for gingival curettage and for removing deposits from the tooth surfaces.

instrument nib,

n the counterpart of the blade in the condensing instrument; the end of the nib is the face.

instrument, parts,

n.pl the handle or shaft, blade or nib, and shank.

instrument, plastic,

n an instrument used to manipulate a plastic restorative material.

instrument, rotary cutting,

n a power-activated instrument used in a dental handpiece, such as a bur, mounted diamond point, mounted carborundum point, wheel stone, or disk.

instrument, screwdriver,

n an instrument made of surgical alloy; it may have at its tip a screw holder that is designed to drive screws into the bone.

instrument shaft/handle,

n the part that is grasped by the clinician's hand while using the instrument.

instrument shank,

n the part that connects the shaft and the blade or nib.

instrument sharpening,

n See sharpening, instrument.

instrument, single-beveled cutting,

n an instrument in which one side of the end of the blade is beveled to form the cutting edge, as in a wood chisel.

Parts of an instrument.

instrument, single-plane,

n an instrument with all its angles and curves in one plane; when the instrument lies on a flat surface, the cutting edge and the blade will parallel the surface.

instrument, sonic,

n a mechanical tool whose thin tip vibrates at high rates and is used to remove debris, deposits, or dead or damaged tissue.

instrument stop,

n a device, usually metal, that can be placed on a reamer or file to mark the measurement of the root.

instrument, toe,

n the tip or terminating end of the blade, may be rounded (blunt) or pointed (sharp).

instrument, universal,

n a tool that may be used on all types of teeth surfaces.

instrumental values,
