Clinical Tips
- All iRaCe Plus files operate at 600 RPM and 1.5 Ncm (per IFU). FKG speed/torque chart shows 400 RPM minimum, 600 RPM optimal.
- iRaCe Plus is indicated when the standard iRaCe R1 (15/.06) cannot reach working length due to narrow, severely curved, or calcified anatomy (per IFU).
- The low .02 taper of R1a and R1b may help navigate difficult anatomy more safely than the standard R1 (15/.06).
- After R1a and R1b reach working length, continue with the standard R2 and R3 to complete preparation.
- Golden rules (per IFU): long back-and-forth gentle strokes; light touch, let the instrument work; 3-4 seconds at a time, then withdraw, clean blade, and irrigate.
- Alternating cutting edges reduce screw-in tendency (per brochure).
- Electropolished surface may improve corrosion resistance (per brochure).
- Safety Memo Disc (SMD) provides visual usage tracking: pull off 1 petal per simple case, 2 per medium case, 4 per difficult case (per IFU).
- Single patient use is recommended to avoid cross-contamination (per IFU). If reprocessed, autoclave at 134°C, 2.2 bar, 18 min per EN/ISO 17664 protocol.
Warnings
- Single patient use is recommended to avoid cross-contamination (per IFU)
- Inspect instruments before use; discard if any visible defects (per IFU)
- Contains nickel — do not use on patients with known nickel allergy (per IFU)
- Do not use phenol, aldehyde, or di-/triethanolamine solutions for disinfection (per IFU)
