Clinical Tips
Motor programming per the IFU: use a WaveOne Gold-compatible reciprocating program, or enter 150° counter-clockwise / 30° clockwise where custom angles are required; speed and torque are defined by the program
The technique is Primary-first: the 25/.07 red file starts every case, the Small 20/.07 is the fallback for canals it cannot enter, and the Medium 35/.06 / Large 45/.05 serve wider canals (IFU)
Completion is judged at the apical flutes — dentinal debris loading after reaching length signals the shape is complete (IFU)
The W+ Tunnel 15/.02 is the system's own reciprocating glide path file; NIC's cross-reference table maps it to reciprocating glide path files and W+ itself to WaveOne Gold — manufacturer-claimed correspondences, not independently verified
MaxTech 3.0 gold heat treatment: the manufacturer describes improved flexibility over standard NiTi with a gold surface appearance, positioned for conventional curvature (~15°)
All five files — the four shapers and the W+ Tunnel — use a parallelogram cross-section per the manufacturer's fact sheet (2026-08-12); the construction pages describe 13 mm short shanks, ISO color coding, and a 1.2 mm maximum flute diameter for the line
Due to heat treatment the file may appear slightly curved out of the package — the manufacturer states this is not a defect and no straightening is needed (IFU)
Do not fully immerse the files in sodium hypochlorite solution (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 reciprocating motion — the IFU directs against continuous rotary motion for these files
- Do not use a file from a damaged package, or any instrument showing deformation, unwinding, corrosion, fracture, or wear (IFU)
- Avoid apical pressure: use a gentle inward pecking motion with short strokes and let the file advance passively (IFU)
- Contains nickel — the IFU contraindicates use in patients with known nickel/NiTi allergic sensitivity
- The IFU contraindicates mechanical use in canals with severe, sudden apical curvatures, complex canal divisions, or anatomy where safe passive file progression cannot be achieved
