About diamond discs
ISO 7711-2 describes diamond discs as commonly used in the dental laboratory to cut dental materials such as metals, ceramics, plastics and gypsum. ISO 10323 sets the bore diameters of discs and wheels so that they and the mandrels they run on are interchangeable.
A dental diamond instrument is an abrasive device: a shaft that goes into a handpiece and a head with diamond chips embedded in it. Its rotation gives an abrasive action, where a bur is a cutting device. The FDA lists it as Class I (21 CFR 872.4535).
ISO 7711-1 sets the general requirements for diamond rotary instruments, including their designation, colour code and grit sizes.
How the types on this shelf differ
- Diamond Burs — A shaped diamond head on its own shaft.
- Diamond Discs — A flat disc for cutting, covered by its own part of the ISO standard.
- Laboratory Diamond Burs — A diamond instrument sized for bench work.
- Laboratory Carbides — Used at the bench on the metals, plastics and porcelains of dental devices, not in the mouth.
- Flexible Silicone Polishers — The abrasive is embedded in a flexible silicone body.
What to look at when choosing a diamond instrument
Grit: ISO 7711-1 covers the grit sizes of diamond instruments and the colour code that marks them. Coarse tools shape the work and remove excess material; medium ones smooth out the grooves and scratches the coarse ones leave.
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.
Shank: the part that fits into the handpiece. ISO 1797 sets shank dimensions and material properties.
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.
