- A large-diameter, short-length nickel-titanium root canal instrument, featuring a 0.04 constant taper, an ISO size #50 tip diameter, and a compact 21mm working length, it is engineered for the final mechanical enlargement of exceptionally wide root canal systems in space-restricted posterior areas
- Comparable to K3™, Vortex™, HyFlex®NT™, Endosequence
Uses
- Final Master Apical Enlargement: Functions as a large master file to complete the mechanical instrumentation of wide root canal configurations (such as palatal roots of maxillary molars or wide distal roots of mandibular molars)
- Posterior Molar Procedures: Optimized for use in molar root networks where limited jaw openings restrict access, allowing the short 21mm shaft to bypass collision with opposing dental arches
- Straight and Wide Canal Clearing: Safely shapes large, straightforward paths and removes persistent calcified obstacles
- Gutta-Percha Extraction: Operates as a robust mechanical extraction tool during retreatment to grab, break up, and evacuate old obturation material from wide canal spaces
- Rotary Sequence Integration: Fits cleanly into engine-driven endodontic techniques structured around constant-taper sequences
- Universal Handpiece Integration:
- Operates reliably across all common rotary endodontic techniques designed for constant-taper sequences
Features
- Super-Elastic USA NiTi Alloy: Manufactured from premium American nickel-titanium alloy, maintaining essential flexibility despite a thick size #50 core structure
- Size #50 Tip Geometry: Outfitted with an ISO standard 0.50mm tip combined with a continuous 0.04 taper for highly uniform canal widening
- No-Rebound Pre-Bending: The advanced metallurgy enables manual pre-bending to enter stubborn orifices safely without a spring-back reaction
- Flute Unwinding Visual Safety: Under excessive torsional stress or binding, the metallic flutes unwind rather than snapping instantly. This provides an obvious visual warning to discard the file
- Color-Coded Handles: Outfitted with a silver handle denoting the 0.04 taper family, coupled with a yellow color ring to identify the size #50 tip
- Industry Compatibility:
- Comparable in function to systems like K3™, Vortex®, HyFlex® NT™, and Endosequence®
Benefits
- Protects Against Broken Instruments: Highly resistant to cyclical fatigue failure caused by repetitive flexing inside the root structure
- Maintains Natural Root Paths: Despite its large diameter, the flexible NiTi core remains centered to minimize structural failures like ledge formation, zipping, transportation, or wall perforation
- Aggressive Cutting Performance: The wide profile cuts through tough dentin walls quickly, minimizing total clinical chair time and improving patient comfort
- Drop-In Compatibility: Directly replaces or supplements existing workflows with systems like K3™, Vortex®, HyFlex®NT™, and Endosequence® without adjustments to motor configurations
- Direct System Compatibility:
- Serves as a seamless clinical alternative to market-leading file sequences like K3™, Vortex®, HyFlex®NT™, and Endosequence® without needing adjustments to pre-set motor settings
