About diamond wheels
Diamond wheels on the diamond rotary instruments shelf are sintered diamond grinding stones and reinforced diamond discs for the lab handpiece.
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.
- Diamond Wheels — Sintered diamond grinding stones and reinforced diamond discs.
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.
