Clinical Tips
- One RECI uses reciprocating motion at 170° CCW / 60° CW angles (per IFU). A reciprocating endodontic motor with programmable angles is needed.
- The patented asymmetric cross-section is designed for cutting efficiency while maintaining canal-centering ability.
- C.Wire heat treatment may provide improved flexibility and cyclic fatigue resistance compared to conventional NiTi (per brochure).
- The three-wave progressive technique (3 up-and-down movements with circumferential filing) is the IFU-recommended approach.
- Five sizes are available (20/.04, 25/.04, 25/.06, 35/.04, 45/.04), allowing size selection based on canal anatomy.
- The IFU procedure pack includes One Flare (coronal pre-flaring), One G / K-Files (glide path), and One RECI (shaping) as a complete workflow.
- Single-use, sterile instrument; supplied in sterile blister packaging.
Warnings
- Single-use instrument (one patient, maximum 5 canals recommended); do not reuse (per IFU: reuse decreases performance and safety characteristics, risk of fracture)
- Do not use in retreatment (per IFU)
- Do not use without first establishing a glide path
- Check the instrument state before use between each canal; if damaged or showing signs of wear, do not use
- Contains nickel-titanium; do not use on patients with known nickel or titanium allergy
- Do not use on children under 2 years of age (ethylene oxide used in sterilization)
- Do not use if packaging is damaged or past expiry date
- In cases of complex anatomy, per-operative risks (breakage, ledge, stripping, zipping) may occur
