About polishing discs
A polishing disc is a flexible disc coated with a fine abrasive, used in a graded set to take a finished surface to a gloss. A review reports that systems reaching the accepted roughness threshold varied between two and five steps, and that single-step systems are not as effective.
Finishing is the contouring of a restoration to the shape wanted; polishing is the use of instruments to reduce the surface irregularities that finishing leaves behind. A glossary defines an abrasive as a substance used for abrading, smoothing or polishing, and polish as a smooth, glossy surface with lustre. A disc is a flat abrasive sheet on a mandrel; the FDA describes abrasive devices as built of abrasives such as diamond chips glued to shellac-based paper and attached to a shank held by a handpiece. The intended job in the same section is to remove excess restorative material and to smooth rough surfaces on oral restorations such as crowns, and the abrasive disk is named in the device list, Class I (21 CFR 872.6010).
Discs come in grades and are worked from coarse to fine: a review reports multi-step abrasive discs as the system with the highest probability of reaching the lowest surface roughness. One common three-step set is described in published work as medium at 40 microns, fine at 24 microns and superfine at 8 microns. A glossary names the result of that sequence the Beilby layer: a relatively scratch-free microcrystalline surface produced by a series of abrasives of decreasing coarseness.
How the types of disc differ
- Polishing discs — Smooths and glosses what is already shaped, rather than cutting through it.
- Abrasive discs — The coarse grades that remove material; the polishing grades follow them.
- Separating and cut-off discs — Cuts through; it is not a grade in a polishing sequence.
- Diamond discs — Diamond on a steel core, under its own standard, rather than abrasive grit on paper.
What to look at when choosing a disc
Grit and sequence: a review of the market notes a wide variety of polishing systems, each with different abrasive compounds and number of steps. Published work on abrasive hardness states that the abrasive particles should be harder than the fillers of the composite and smaller than those fillers, so they do not scratch the surface.
Abrasive compound: compounds used in polishing protocols include aluminium oxide, silicon dioxide and diamond.
What counts as smooth enough: a review states that a roughness below 0.2 microns is generally accepted as the threshold, above which bacterial retention can occur, and that a patient can feel roughness above 0.3 microns with the tongue.
Speed: a review reports evidence that 15,000 rpm was the preferred speed for low roughness and high gloss, and that each step held for 60 seconds with water coolant gave the lowest roughness and the highest gloss.
Shape code: ISO 6360-2 codes the shapes of all dental rotary instruments and of several accessories used with them.
