Key Specifics About Veterinary Dental Burs

Dental burs bring cutting hard tissues – tooth or bone. They are made of steel, stainless steel, tungsten carbide and diamond grit. There can be a bewildering array of dental burs in a dental catalogue, but for basic veterinary only use a number of burs are essential.

All burs have a shank as well as a head. You will find three main varieties of shank – Long Straight Shank (HP), Latch-type Shank (RA) Grip Shank (FG)

Long Straight Shank (HP)
These shanks squeeze into the nose cone of the slow speed handpiece once the prophy angle or contra angle is slowly removed. They are used for diamond cutting discs or long 40mm burs. The main use of HP burs influences trimming of small herbivore cheek teeth.

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

Friction Grip Shank (FG)
These shanks match the turbine of an high-speed handpiece. The conventional length is 20mm long, but longer surgical lengths can be purchased which are commonly essential for veterinary work.

Round Head
These heads are used for cavity preparation, creating access points, undercuts and channels for luxator blades in extraction. Sizes range from 1/4 to 9. The lesser the telephone number, the lesser the pinnacle. The most effective sizes to use initially are 1, 2, and 4.

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

Crosscut Tapered Fissure Head
These heads can be used 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 can be used finishing restorations, soft tissue recontouring, alveolaplasty, enameloplasty and odontoplasty. They are often obtained as 12 or 30 bladed burs in carbide steel or as diamond heads of assorted shapes. They are also available as white stone, for composite, or green stone, for amalgam.
