About polishing and finishing kits
A polishing and finishing kit holds the whole graded sequence for one material, so the steps come matched to each other. 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 polishing kit is one graded set in a box: the instruments for each step of a sequence, sold together. That matters because the steps are what a system is: a review notes a wide variety of polishing systems, each with different abrasive compounds and number of steps.
The sequence runs from coarse to fine: published work describes conventional protocols as a series of abrasives that gradually decrease in coarseness. Each later grade exists to remove the scratches the one before it left, until a high-gloss surface is reached. A glossary calls the end result the Beilby layer: a relatively scratch-free microcrystalline surface produced by a series of abrasives of decreasing coarseness.
How the kinds of kit on this shelf differ
- Polishing and finishing kits — The complete sequence in a box, where the other sets on this shelf are one step of it in several forms.
- Flexible silicone polishers — All one kind of instrument in several grades or shapes, rather than a mixture of disc, point and paste.
- Polishing paste — The last step of a sequence rather than the whole of it; the FDA regulates the paste itself as an oral cavity abrasive polishing agent.
What to look at when choosing a polishing kit
Number of steps: a review reports multi-step abrasive discs as the system with the highest probability of reaching the lowest surface roughness.
What material it is graded for: a review notes that ceramic systems need a minimum of two steps, with coarse-grit finishing and medium-grit polishing.
What is in the box: kits hold discs, rubber cups and points, brushes, stones or pastes, which a review lists among the tools used.
Grit values: one three-step set is described in published work as medium at 40 microns, fine at 24 microns and superfine at 8 microns.
Time per step: a review notes that each step was indicated to be held for 60 seconds with water coolant for the lowest roughness and the highest gloss.
