About mounted stones
A mounted stone is a bonded abrasive already fixed to its own shank, so it goes straight into a handpiece without a separate mandrel. Published work describes stones used in the chair to adjust the tightness of a proximal contact, a job clinicians have long done with stones or silicone.
A stone is a bonded abrasive: grit held in a rigid body that grinds rather than flexes, and a glossary defines an abrasive as a substance used for abrading, smoothing or polishing. The same glossary adds abrasivity, the property of one material to wear away another material by means of frictional contact. Published work describes a white stone as a dental rotary instrument of conical or round shape, made of fine-grain aluminium oxide. A review names dental stones among the tools used in finishing and polishing, with rubber cups and points and abrasive discs.
ISO 6360-6 codes rotary abrasive instruments and treats dental polishers as abrasive instruments too, so stones and polishers share one coding scheme. ISO 8325 names grinding instruments alongside burs, cutters and polishers as rotary instruments covered by its test methods for dimensional characteristics, neck strength and surface roughness.
How the types of stone and abrasive differ
- Mounted stones — Already on a shank; a heatless wheel or an abrasive block is not.
- Finishing stones — Fine grade for refining form, where a grinding grade removes material.
- Rubber abrasive points and cones — A rubber binder, so it flexes where a stone of the same shape stays rigid.
- Rubber abrasive wheels — A wheel rather than a point or cone, in the same rubber binder.
- Heatless wheels — Unmounted, so it needs the spindle a glossary calls a mandrel: the shaft and bearings on which a tool is mounted.
- Abrasive blocks and sticks — Held in the hand, not driven by a handpiece.
- Wheel dressers — Works on the instrument rather than on the restoration.
What to look at when choosing a stone
Grit and material: published work on surface finishing names aluminium oxide, zirconium oxide, quartz, carbon steel, diamond and tungsten carbide among the abrasive materials used.
Hardness: published work states that the abrasive particles should be harder than the fillers of the material being worked.
What follows it: published work on proximal adjustment notes that after a stone has been used there is usually a need to polish the area.
Mounted or not: a mounted stone runs on its own shank, and an unmounted wheel needs the spindle a glossary calls a mandrel.
Cleaning: published guidance says to follow the maker instructions for cleaning and sterilizing or disinfecting items that become contaminated but do not normally contact the patient, and names polishing points among them.
