RMH3 Dental FG White Stones — 12/Pack · Inverted Cone IC2

• 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.

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.
