Zirconia Grinding
ERADENT’s Zirconia Grinding and Polishing Bur combines diamond abrasives with zirconia-enhanced bonding technology, designed for rapid dry finishing of zirconia crowns, bridges, and abutments. Optimized for chairside and lab workflows, it eliminates water-cooling requirements while maintaining ≤2°C temperature rise at 25,000 RPM
Specification
| Parameter | Details |
| Abrasive Composition | Diamond-zirconia hybrid matrix (density 6.0g/cm³, hardness 1100GPa) |
| Grit | Medium (40–60 μm) |
| Speed Compatibility | 7,000–25,000 RPM (optimal performance at 20,000–28,000 RPM) |
| Shank Diameter | 2.35 mm (ISO 1797-1 compliant) |
| Thermal Stability | Heat-resistant up to 120°C (dry operation certified) |
| Packaging | Sterile single-unit plastic case (10 units/display box) |
Advantage
- Waterless Operation: Proprietary cooling channels reduce friction heat by 60% vs. conventional burs.
- Dual-Action Efficiency:
- Step 1: 150 μm diamond grit removes zirconia excess at 0.2 mm/sec (lab-tested)
- Step 2: 10 μm polishing achieves Ra ≤0.1 μm surface roughness
- Extended Lifespan: 3x longer durability than resin-bonded alternatives (50+ restorations/bur).
- Multi-Material Adaptability: Effective on:
- Zirconia: Full-contour crowns & hybrid abutments
- Lithium Disilicate: Margin refinement without chipping
- PMMA: Denture base adjustments
