Clinical Tips
Crown-down approach: always start with 25/.04 and step down only if needed
Compatible with Vortex, ProFile, K3, Sequence, TF, and other .04/.06 rotary systems
Fire-Wire AHT eliminates shape memory - files contour to canal anatomy (Canal Contouring Technology)
Files may arrive slightly curved from manufacturing - this is normal, not a defect
Maximum flute diameter of 1mm allows minimally invasive preparation
Reduced handle length improves posterior access
Electropolished blade increases sharpness and smoother canal navigation
Enhanced cyclic fatigue resistance vs leading files — manufacturer reports excellent fatigue performance (bench data; exact comparisons vary by source)
Warnings
- Single use only — delivered sterile, do not reuse or reprocess (per 2026 IFU)
- Do not use if sterile seal is broken, damaged, or wet (per 2026 IFU)
- Up to four canals during a single procedure (per 2026 IFU)
- Contains nickel-titanium and silicone — do not use on patients with known sensitivity
- Files may unwind — this is a safety feature, not a defect
- Use only with electric handpiece/motor — not air-driven
- Do not force the file down the canal — apply only minimal apical pressure
- Clean flutes frequently — do not allow flutes to clog
- Discard if cracks, corrosion, deformation, or loss of markings observed (per 2026 IFU)
Obturation Techniques

Frequently Asked Questions
01What alloy is EdgeFile X7 made from?
01
What alloy is EdgeFile X7 made from?
Answer
EdgeFile® X7 is manufactured from Fire-Wire™ Annealed Heat-Treated NiTi.
02How many files are in the EdgeFile X7 sequence?
02
How many files are in the EdgeFile X7 sequence?
Answer
The EdgeFile® X7 system includes 14 files: 17/.
- 0104, 20/.
- 0204, 25/.
- 0304, 30/.
- 0404, 35/.
- 0504, 40/.
- 0604, 45/.
- 0704, 17/.
- 0806, 20/.
- 0906, 25/.
- 1006, 30/.
- 1106, 35/.
- 1206, 40/.
- 1306, 45/.
- 1406.
03What is the EdgeFile X7 file sequence?
03
What is the EdgeFile X7 file sequence?
Answer
EdgeFile X7 has no multi-file sequence: the DFU describes starting every canal with 25/.
- 0104 and stepping down only when it does not reach working length (withdraw, irrigate, recapitulate, then 20/.
- 0204 and, if needed, 17/.
- 0304) before returning to 25/.
- 0404.
- 05If a larger apical size is wanted, sizes are increased one at a time (30/.
- 0604, 35/.
- 0704 and up) without skipping.
- 08Speed and torque are in the protocol section above.
04What motion type does EdgeFile X7 use?
04
What motion type does EdgeFile X7 use?
Answer
EdgeFile® X7 uses continuous rotation motion.
05What cases is EdgeFile X7 best for?
05
What cases is EdgeFile X7 best for?
Answer
EdgeFile® X7 is best suited for: crown-down rotary with enhanced fatigue resistance, dual taper versatility (.
- 0104/.
- 0206), mid-cost North American market.
06What speed and torque settings are recommended for EdgeFile X7?
06
What speed and torque settings are recommended for EdgeFile X7?
Answer
Recommended settings: 300-500 RPM and 300 g-cm across the file sequence (refer to official DFU for full per-file parameters).
