Necessary Details About Veterinary Dental Burs

Dental burs bring cutting hard tissues – tooth or bone. They may be made from steel, stainless-steel, tungsten carbide and diamond grit. There might be a bewildering variety of dental burs in almost any dental catalogue, but also for basic veterinary only use a couple of burs are required.

All burs have a very shank along with a head. You’ll find three main forms of shank – Long Straight Shank (HP), Latch-type Shank (RA) and Friction Grip Shank (FG)

Long Straight Shank (HP)
These shanks squeeze into the nose cone with the slow speed handpiece as soon as the prophy angle or contra angle is removed. They are used for diamond cutting discs or long 40mm burs. The key usage of HP burs is incorporated in the trimming of small herbivore cheek teeth.

Latch-type Shank (RA)
These shanks match the latch of the contra-angle on slow speed handpieces. They are often 20mm long and available in the identical shapes as FG burs.

Friction Grip Shank (FG)
These shanks squeeze into the turbine of a high-speed handpiece. The conventional length is 20mm long, but longer surgical lengths can be found and these are generally needed for veterinary work.

Round Head
These heads can be used for cavity preparation, creating access points, undercuts and channels for luxator blades in extraction. Sizes range from 1/4 to 9. Smaller the number, the lesser the top. The top sizes to work with initially are 1, 2, and 4.

Pear Head
These heads are used for cavity preparation, access points and splitting roots of small teeth. Probably the most useful sizes are 330 and 330L

Crosscut Tapered Fissure Head
These heads can be used for sectioning multi-rooted teeth and reducing crown height when disarming dogs. The most useful sizes are 700/700L and 701/701L.

Finishing Burs
These heads bring finishing restorations, soft tissue recontouring, alveolaplasty, enameloplasty and odontoplasty. They could be obtained as 12 or 30 bladed burs in carbide steel or as diamond heads of varied shapes. They’re also like white stone, for composite, or green stone, for amalgam.
