Micro-Mega (COLTENE)
MicroMega One Flare®
Dedicated coronal flaring instrument with 9% taper and 17 mm length, designed to reduce interferences at the canal entrance before shaping
| File | Tip | Taper | Speed rpm | Torque Ncm | Role |
|---|---|---|---|---|---|
| One Flare 25/.09 | 0.25 | 9% | 250-400 | 3.0 | Orifice opener |
One Flare uses 250-400 RPM with a maximum torque of 3.0 Ncm (per IFU). Any continuous-rotation endodontic motor may be used.
The 9% taper and 17 mm length are designed specifically for coronal pre-flaring, not full canal shaping.
T.Wire heat treatment may provide improved fatigue resistance and increased flexibility compared to conventional NiTi (per brochure).
Pre-flaring with One Flare may help refocus the glide path and reduce the risk of fracture for subsequent penetration instruments.
The instrument is sterile and reusable; the IFU recommends a maximum of 5 canals per instrument if not visibly damaged.
Sold in 5-piece packs. Inspect each instrument before use between each canal.
