- Mostly used for the final finish on zirconia.
- Reaches into fissures and occlusal grooves where the wheels cannot.
- Coarse, Medium and Fine.
The brushes sit in the polishing range, but it is on zirconia that they do the most good. They reach into fissures and occlusal grooves a wheel cannot get to, and give an even surface without rounding off the anatomy. Coarse where there is a lot to remove, Fine as the last step.
