Scotch-Brite Brushes 25 mm for Dental Pre-polishing
Référence: H140560
Scotch-Brite Brushes 25 mm — pre-polishing of resins & polyamides
Essential rotary instruments for pre-polishing and cleaning dental prostheses, orthodontic appliances and splints. Their controlled abrasive Scotch-Brite structure efficiently removes residues without damaging the surface. Available in two densities (fine/coarse), fitted with a 2.35 mm shank, diameter 25 mm.
- 3 grit options: fine, medium & coarse
- Ø 25 mm — standard 2.35 mm shank
- Resin, polyamide, metal, ceramic
Features & advantages
- Non-aggressive abrasive material preserving surface integrity while effectively removing residues.
- High versatility: resins, polyamides, and gentle finishing on metal or ceramic prior to final polishing.
- Two densities (fine/coarse) to adapt material removal to each working stage.
- Excellent control at low to medium speed to reduce heat build-up and premature wear.
Applications
- Cleaning of dental prostheses after rough grinding.
- Surface preparation and finishing prior to bonding or final polishing.
- Removal of plaster or adhesive residues from resin surfaces and difficult areas.
- Ideal for rounding and smoothing edges of thermoformed splints and mouthguards.
Usage recommendations
- Operate at low to medium speed to prevent overheating and deformation.
- Clean the brush regularly to maintain cutting efficiency.
- Select the appropriate grit density: coarse for pre-grinding, fine for surface uniformity.

FAQ — frequently asked questions
Which grit should be selected (fine or coarse)?
The coarse grit is recommended for pre-grinding and fast removal of stubborn residues such as plaster, adhesives or rough areas on thicker resins or polyamides.
It removes material efficiently but leaves a more pronounced surface texture that will require further refinement.
The fine grit is intended for surface finishing and preparation prior to final polishing or bonding procedures; it smooths without gouging and limits micro-scratches.
The recommended workflow is to alternate: coarse for opening, fine for finishing.
Which materials and operating speeds are recommended?
Scotch-Brite brushes perform very effectively on resins (PMMA), polyamides, and for gentle preparation on metal or ceramic prior to final polishing.
Use low to medium rotational speed to prevent heat generation that could soften resin and clog the abrasive fibers.
Apply short, light contacts without excessive pressure, allowing the abrasive structure to do the work.
If loading occurs, quick cleaning with a brush or compressed air restores cutting efficiency and extends service life.
How can the service life of the brushes be extended?
Avoid continuous pressure and apply light, controlled strokes, allowing the abrasive to act progressively.
Clean the brushes regularly to remove accumulated debris and restore cutting performance.
Alternate between grit densities, using coarse only when necessary and switching to fine for smoothing to reduce premature wear.
Store brushes protected from dust and separate them by application (resin, polyamide) to avoid cross-contamination.
When efficiency decreases, replacement ensures consistent surface quality and reduced finishing time.
How do these differ from nylon brushes or abrasive rubbers?
Scotch-Brite brushes provide controlled abrasiveness superior to nylon brushes while remaining gentler than many abrasive rubbers.
They are particularly effective for pre-polishing and cleaning without digging into the material, where nylon may be insufficient and rubber too aggressive.
Their fibrous structure adapts well to curves and difficult areas with reduced clogging when used at moderate speed and light pressure.
For final high-gloss results, complete the process with felts and appropriate polishing compounds after the fine-grit stage.
