Description
The ATTRITOR COMPOSITE Polishing Brush is a silicone-impregnated nylon-bristle polisher engineered for the final high-shine stage on COMPOSITE resin restorations. The bristle geometry presents a soft, conforming contact patch that follows the restoration's natural surface contour — ideal for the anterior facial face, the incisal edge, and the fine occlusal anatomy of posterior composites.
- ✓Silicone-impregnated nylon-bristle polisher for COMPOSITE resin
- ✓Soft conforming contact patch follows surface contour
- ✓Final high-shine stage for COMPOSITE restorations
- ✓Indicated for direct and indirect COMPOSITE resin restorations
- ✓RA mandrel for chairside or laboratory contra-angle handpiece use
✦Why You'll Love It
✦Soft conforming bristle contact follows the restoration's natural anatomy without flattening occlusal cusps or the anterior incisal line.
✦Engineered for COMPOSITE specifically — not a generic ceramic polisher repurposed for resin.
✦RA-mounted — direct contra-angle use chairside or lab-side.
✦Three grit grades — Coarse for initial refinement, Medium for pre-shine, Fine for the final mirror.
Materials & Construction
Bristles: silicone-impregnated nylon, color-coded by grit.
Operating Speed & Use Guidance
Recommended operating range: 4,000–8,000 RPM in contra-angle handpiece — lower than ceramic Polishers because the bristles are sensitive to heat.
Very light contact pressure — let the bristles glide. Pressure flattens the brush and degrades finish quality.
Sterilization & Handling
- ✓Autoclavable per the manufacturer's bristle-care protocol — do not exceed published temperature/cycle limits
- ✓Pre-clean COMPOSITE residue from the bristles before sterilization
