Burs, Surgical, Bone, Cranial Definition: Bone surgical burs designed to excavate the cranium and adjacent areas, frequently to open holes in the cranium. These burs typically consist of a shank made of steel or tungsten carbide with a well-differentiated working head in a variety of sizes and shapes (e.g., round, cylinder, inverted cone) on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Cranial burs are used mainly in neurosurgical procedures (e.g., craniotomies) involving the brain; they are usually intended for reuse after sterilization.
BUR, DENTAL Definition: A dental bur is a rotary cutting device made from carbon steel or tungsten carbide intended to cut hard structures in the mouth, such as teeth or bone. It is also intended to cut hard metals, plastics, porcelains, and similar materials intended for use in the fabrication of dental devices.
DRILL, DENTAL, INTRAORAL Definition: An intraoral dental drill is a rotary device intended to be attached to a dental handpiece to drill holes in teeth to secure cast or preformed pins to retain operative dental appliances.
Burs, Dental Definition: Burs designed to be held and rotated by a dental handpiece (manual, electrical, or pneumatic powered) to excavate teeth and/or dental restorations. These burs typically consist of a shank made of tungsten carbide or, less frequently, steel, with a well-differentiated working head (sometimes with bound diamond chips or covered with diamond film) in a variety of sizes and shapes (e.g., round, cylinder, inverted cone, pear, end/side cutting) on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Dedicated dental burs are available for many different uses, including removal of carious material from teeth, dental cavity preparation, and finishing and polishing of teeth and restorations (e.g., porcelain, metal). They are usually intended for reuse after sterilization, but disposable (single use) burs (e.g., diamond burs) are also available.
Burs, Dental, Carbide Definition: Dental burs made of tungsten carbide that are usually intended for use with ultra-high-speed rotary dental handpieces. These burs typically consist of a shank with a well-differentiated working head in a variety of sizes and shapes (e.g., cone, cylinder, inverted cone, pear) on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Dedicated carbide dental burs are available for many different uses, including removal of carious material from teeth, dental cavity preparation, and finishing and polishing of teeth and restorations (e.g., porcelain, metal). They are usually intended for reuse after sterilization, but disposable (single use) carbide burs are also available.
INSTRUMENT, DIAMOND, DENTAL Definition: A dental diamond instrument is an abrasive device intended to smooth tooth surfaces during the fitting of crowns or bridges. The device consists of a shaft which is inserted into a handpiece and a head which has diamond chips imbedded into it. Rotation of the diamond instrument provides an abrasive action when it contacts a tooth.
Burs, Dental, Diamond Definition: A rotary cutting device, the working end of which is made from steel coated with small diamond crystals, that is designed to fit into a dental handpiece and intended to cut hard structures in the mouth, such as teeth or bone. Diamond burs can also be used to cut hard metals, plastics, porcelains, and similar materials. Dental burs with a working head that includes bound diamond chips or is covered with diamond film are usually intended for use with ultra-high-speed rotary dental handpieces. These burs typically consist of a shank with a well-differentiated working head in a variety of sizes and shapes (e.g., cone, cylinder, inverted cone, pear) on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Dedicated diamond dental burs, either disposable or reusable, are available for many different uses, including removal of carious material from teeth, dental cavity preparation, and finishing and polishing of teeth and restorations (e.g., porcelain, metal); they are particularly useful to prepare teeth for indirect restorations.
Burs, Dental, Steel Definition: Dental burs made of steel that are usually intended for use with low-speed rotary dental handpieces. These burs typically consist of a shank with a well-differentiated working head in a variety of sizes and shapes (e.g., cone, cylinder, inverted cone, pear) on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Dedicated steel dental burs are available for many different uses, including removal of carious material from teeth, dental cavity preparation, and finishing and polishing of teeth and restorations (e.g., porcelain, metal). They are usually intended for reuse after sterilization, but steel burs rapidly become dull after cutting dental enamel or other very hard materials.
Guides, Drill Definition: Devices designed to simultaneously direct the placement of the drill hole and protect the surrounding tissue.
BUR Definition: An ear, nose, and throat bur is a device consisting of an interchangeable drill bit that is intended for use in an ear, nose, and throat electric or pneumatic surgical drill (Sec. 874.4250) for incising or removing bone in the ear, nose, or throat area. The bur consists of a carbide cutting tip on a metal shank or a coating of diamond on a metal shank. The device is used in mastoid surgery, frontal sinus surgery, and surgery of the facial nerves.
BURR Definition: An orthopedic manual surgical instrument is a nonpowered hand-held device intended for medical purposes to manipulate tissue, or for use with other devices in orthopedic surgery. This generic type of device includes the cerclage applier, awl, bender, drill brace, broach, burr, corkscrew, countersink, pin crimper, wire cutter, prosthesis driver, extractor, file, fork, needle holder, impactor, bending or contouring instrument, compression instrument, passer, socket positioner, probe, femoral neck punch, socket pusher, reamer, rongeur, scissors, screwdriver, bone skid, staple driver, bone screw starter, surgical stripper, tamp, bone tap, trephine, wire twister, and wrench.
Burs Definition: Small instruments designed to be held and rotated by a device (e.g., handpiece, drilling machine) to excavate, perforate, reshape, and/or excise objects, tissue, or other anatomic parts. These instruments typically consist of a shank of steel or other hard metal with a well-differentiated working head of various shapes (e.g., cone, cylinder, inverted cone, pear) on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Dedicated burs are used in a variety of dental and surgical (e.g., orthopedic, ophthalmic, endaural) procedures.
