About laboratory carbides
ISO 7787-2 covers the 11 most commonly used carbide cutters, which are predominantly used in the dental laboratory. In a published denture study acrylic was finished with tungsten carbide burs at 10,000 rpm before it was sanded and polished.
A dental bur is a rotary cutting device made from carbon steel or tungsten carbide. The FDA lists it as a Class I device (21 CFR 872.3240), for cutting teeth and bone and also the hard metals, plastics and porcelains that dental devices are made from. A carbide bur is one made from tungsten carbide.
The head is the cutting portion of a bur, and the shank is the part that fits into the handpiece. ISO 6360 identifies every dental rotary instrument by a 15-digit number.
How the types on this shelf differ
- Finishing Carbides — A bur made to finish a surface.
- Laboratory Carbides — Used at the bench on the metals, plastics and porcelains of dental devices, not in the mouth.
- Cross-Cut Burs — Named for its blade pattern.
- Operative Carbides — Made for cutting tooth structure, where a laboratory carbide is made for the bench.
- Diamond Burs — A shaped diamond head on its own shaft.
- Flexible Silicone Polishers — The abrasive is embedded in a flexible silicone body.
The shelf also files burs as specialty carbides and as kits; no source on our allowed list defines those groups, so this guide does not describe them.
What to look at when choosing a carbide bur
Head shape: the outline of the cutting edges, described from the shank to the tip.
Shank: the shaft of a bur is friction-grip or latch-type. ISO 1797 sets shank dimensions and material properties.
Size: ISO 2157 sets the nominal diameters of the working part of burs, laboratory burs, grinding instruments, diamond instruments and mandrels, and how they are designated.
Reuse: the CDC states that burs, polishing points and rag wheels used on contaminated appliances or prostheses should be heat-sterilised, disinfected between patients, or discarded.
