Orthodontic Instruments: Names, Uses and FDA Class

Orthodontic instrument names matched to their jobs (pliers, cutters, band and bracket tools), with their FDA Class I status under 21 CFR 872.4565.

This page describes products and general use; it is not medical advice.

Orthodontic instruments are the hand tools used to handle archwires, ligatures, bands and brackets in orthodontic care. This page is for clinic staff, buyers and dental students who need to match an instrument name to its job, and it also records how FDA classifies dental hand instruments, a point most name lists leave out.

What counts as an orthodontic instrument?

An orthodontic instrument is a hand-held tool used for orthodontic work: holding, bending or cutting wire, placing or removing bands, and handling brackets. The University of Toronto Faculty of Dentistry notes that many of these instruments are unique to orthodontics, while a few, such as the mouth mirror, are general dental tools used during orthodontic procedures (University of Toronto Faculty of Dentistry, “Orthodontic Instruments”, checked 2026-10-31).

Who uses them: orthodontists, dental assistants and dental students.

Pliers and cutters: names and jobs

The table groups the pliers and cutters described by the University of Toronto Faculty of Dentistry by what each is used for (checked 2026-10-31).

Group Instrument What it does
Holding archwires Howe utility pliers Two long beaks with pads at the ends, used to hold archwires during placement and removal.
Bending wire Bird beak (139) plier Pyramidal and conical beaks, used for making bends in orthodontic wires.
Cutting Wire cutter / pin and ligature cutter Tapered beaks with sharp cutting ends, used for small-diameter wires (less than 0.015 inches) and for stainless steel ligatures.
Cutting Distal end cutters Cutting surfaces at right angles to the long axis, used to cut the terminal end of a ligated archwire; they also catch and hold the cut end so the loose wire does not injure the patient.
Ligatures Mathieu plier A quick release locking and unlocking mechanism, used for placing elastomeric ligatures.
Spacing Separating pliers Reverse action pliers that hold separating modules and stretch the separators for placement on the teeth.
Isolation Cotton pliers Used to place cotton rolls for isolation and to retrieve small objects intra-orally.

Band-placing and band-removing instruments

Bands have their own set of tools, each with a different working end (University of Toronto Faculty of Dentistry, checked 2026-10-31):

  • Band pusher: long handle with an angled, rectangular, serrated tip, used to fit and position a band on a tooth.
  • Bite stick: long-handled nylon instrument with a serrated tip, used to seat bands using the patient’s biting force.
  • Band burnisher: looks like a band pusher but with a flatter working end, used to adapt and contour a band to the tooth.
  • Posterior band remover: a nylon-tipped beak and a flat, slightly curved beak, used to remove bands on posterior teeth.

For the part these tools work on, see orthodontic bands.

Bonding and isolation instruments

  • Bracket holder (bracket tweezer): a reverse action instrument with two fine angled tips, used to hold and place brackets.
  • Plastic filling instrument: used to place composite onto the mesh pad of a bracket before bonding.
  • Straight probe: aids in positioning brackets, removes excess composite around brackets and removes elastomeric ligatures from brackets.
  • Mouth mirror: used for visualization and retraction; not specific to orthodontics.

Related parts have their own pages: orthodontic brackets, orthodontic archwires and orthodontic power chain.

Which names vary?

Some instruments carry more than one name: the wire cutter is also called a pin and ligature cutter, the bird beak plier is also called a 139 plier, and the bracket holder is also called a bracket tweezer. Matching an instrument by its working end and function, as in the table and lists above, is more reliable than relying on a single name.

How does FDA classify orthodontic hand instruments?

Under 21 CFR 872.4565, a dental hand instrument is a hand-held device intended to perform various tasks in general dentistry and oral surgery procedures. The regulation’s identification list names “orthodontic pliers”, along with orthodontic band drivers, pushers and setters. It classifies the device as Class I (general controls). If the device is made of the same materials used before May 28, 1976, it is exempt from premarket notification, subject to the limitations in 21 CFR 872.9 (21 CFR 872.4565, checked 2026-10-31).

Question Answer from the regulation
Regulation 21 CFR 872.4565, Dental hand instrument
Class Class I (general controls)
Premarket notification Exempt if made of the same materials used before May 28, 1976, subject to the limitations in 21 CFR 872.9

Safe use and handling basics

The cutting instruments show the main handling point in the source material: distal end cutters are designed to catch and hold the cut wire end so it cannot injure the patient. Cleaning and sterilization of any reusable instrument follow the manufacturer’s instructions for use and the facility’s reprocessing policy. For the general reprocessing context, see dental surgical instruments and the related dental pliers page.

Common mistakes

  • Treating the wire cutter and distal end cutters as the same tool. The first is used on small-diameter wire and ligatures; the second cuts the end of a ligated archwire and holds the cut piece.
  • Confusing the band pusher with the band burnisher. They look alike, but the burnisher’s working end is flatter and is used to contour the band.
  • Relying on one name alone. “Bird beak” and “139” are two names for the same plier, and the wire cutter is also called a pin and ligature cutter.

FAQ

What is the plier used to bend wire called?

The bird beak plier, also called the 139 plier, has pyramidal and conical beaks and is used for making bends in orthodontic wires.

What cuts the end of an archwire?

Distal end cutters are used for intra-oral cutting of the terminal end of a ligated archwire, and they catch and hold the cut end so it does not injure the patient.

What holds an archwire during placement and removal?

Howe utility pliers: two long beaks with pads at the ends, used to hold archwires during placement and removal.

Are orthodontic pliers regulated by FDA?

They are covered. They are named in the dental hand instrument identification of 21 CFR 872.4565, which is Class I (general controls).
