Clinical Tips
Motor settings 300-500 RPM / 3.0 Ncm per the manufacturer's consolidated fact sheet (2026-08-12), which supersedes the catalog's earlier 350-400 RPM / 3-3.5 Ncm; the IFU draft itself defers to the product label
The IFU warns against copying speed or torque settings published for other manufacturers' file systems
Workflow per the IFU: 17/.04 establishes the rotary pathway, 25/.04 is the primary shaper, and 30-45 are used sequentially only when a larger apical preparation is clinically indicated
Alloy: the manufacturer's consolidated fact sheet (2026-08-12) names the tier MaxTech High Flex (Controlled Memory Wire) — a newer proprietary heat treatment outside the published 3.0/6.0/9.0 numbering that NIC had earlier positioned closest to its 9.0 CM-class
CM-wire-class behavior per the IFU: high flexibility, reduced shape memory, and the ability to follow canal curvature without actively straightening the anatomy; the file may show a slight natural curve out of the package
The size range runs to 45 in both tapers per the IFU and the fact sheet (the 2025 catalog listed 17-40); the two 45 configurations have no product render yet
Cross-section: parabolic per the manufacturer's consolidated fact sheet (2026-08-12), which restores the catalog's term and supersedes the IFU draft's triangular description; non-cutting guiding tip, 0.8-1.0 mm maximum flute diameter, 11 mm handle
NIC's own cross-reference table maps the MH File to EdgeEndo X7 — a manufacturer-claimed correspondence, not independently verified
Constant tapers (.04/.06) are positioned by the manufacturer for straightforward obturation planning with matching points
Supplied 6 instruments per pack (IFU)
Specifications on this page come from the manufacturer's consolidated fact sheet (2026-08-12, the controlling source), IFU draft (2026), and 2025 catalog; no independent peer-reviewed performance data exists for this system (PubMed, 2026-08-11)
Warnings
- Single-use only per the manufacturer's IFU — reuse may increase the risk of cross-contamination, loss of cutting efficiency, or file separation
- Supplied non-sterile in this version: sterilize before first clinical use (steam autoclave 134 °C, 18 min holding time per the IFU) and discard after the procedure
- Use only in continuous clockwise rotation with a torque-controlled motor — the IFU directs against reciprocating motion
- Follow the speed and torque on the current NIC label for your files; the IFU warns against carrying over settings from other manufacturers' systems
- Do not use a file from a damaged package, or any instrument showing deformation, unwinding, corrosion, fracture, or wear (IFU)
- Avoid apical pressure: withdraw, irrigate, recapitulate, and use a smaller file rather than forcing advancement (IFU)
- Contains nickel-titanium — the IFU contraindicates use in patients with known allergic sensitivity to the material
- The IFU contraindicates mechanical use in canals with severe, sudden apical curvatures, complex canal divisions, calcified anatomy, or anatomy where safe passive file progression cannot be achieved
