Description
Flexer Heat Activation Engine MX-C3 25mm series is a high-performance rotary NiTi file system designed for precision, safety, and efficiency in endodontic canal preparation. Manufactured using heat-activated nickel-titanium alloy, these files provide exceptional flexibility, superior cyclic fatigue resistance, and optimal control during shaping. The M-series (M1 & M2) and C-series (C1, C2 & C3) files offer a comprehensive sequence that allows smooth and progressive canal enlargement – from coronal access to apical finishing.
DIRECTIONS TO USE
Establish a manual glide path with hand files up to size #15 or #20.
Start shaping with C1 for coronal third, then C2, followed by C3 for apical preparation.
Proceed with M1 and M2 files for final shaping and refinement.
Operate each file at 300–500 rpm and 2–3 Ncm torque, using a gentle pecking motion without applying pressure.
Irrigate the canal frequently with sodium hypochlorite to remove debris and lubricate.
After use, clean, inspect, and discard files to avoid fatigue-related fracture.
KEY FEATURES
Heat-treated NiTi alloy ensures superior flexibility and reduced fracture risk.
MX-C3 design enhances shaping efficiency with smooth cutting performance.
25mm length ideal for deep canals and longer root anatomies.
M1 & M2 files provide efficient canal enlargement and controlled cutting.
C1, C2 & C3 files enable stepwise progression for coronal, middle, and apical shaping.
Smooth surface finish minimizes friction and enhances debris evacuation.
Compatible with most rotary endo motors at speeds of 300–500 rpm and 2–3 Ncm torque.
Ensures excellent canal centering ability and preservation of natural canal curvature.
Sterilizable and single-use for safety and consistent performance.
