NiTi Rotary Tapered Protaper Files Endodontic Products

Design Features

• Taper design: Large progressive taper enables multi-zone shaping with a single file, delivering powerful root canal shaping performance.
• Cross-section: Convex triangular shape, with a small contact area, high cutting efficiency, low friction, and less likely to get stuck in the root canal walls.
• Flute design: Spiral flute structure ensures uniform cutting and smooth chip evacuation.
• Tip: Safe non-cutting tip effectively protects apical tissues.

• Handling: Smooth file body with minimal resistance provides excellent operational controllability.

Model Function Division

• SX (Pioneer File)：19mm short length with no color ring. It is specially used for short posterior root canals to establish coronal patency and quickly open the canal orifice.
• S1 (Purple ring)：Performs preliminary shaping on the coronal and middle segments of root canals, forming a standard “wide coronally, narrow apically” canal morphology.
• S2 (White ring)：Finely trims the middle canal segment, optimizing the passage for apical finishing files and avoiding ledges or canal transportation.
• F1 (Yellow ring)：Specially designed for apical preparation and final finishing of fine and narrow root canals.
• F2 (Red ring)：The final finishing file for standard root canals, creating an ideal canal shape for root canal obturation.
• F3 (Blue ring)：Suitable for large root canals and canals with apical resorption. It completes large-diameter apical finishing for special and complex clinical cases.

Core Features

• Comprehensive Structural Design: Includes a six‑file set (SX, S1, S2, F1, F2, F3) with two lengths (21mm/25mm). Designed for crown‑down preparation with clearly defined functions, enabling full‑sequence root canal preparation from the canal orifice to the apical zone.
• Superior Material Performance: Made of nickel‑titanium alloy, offering high elasticity, flexibility, and excellent resistance to bending and torsional stress. Suitable for curved root canals, ensuring high stability and safety.
• Clinically Safe and Reliable: Helps prevent complications such as apical perforation, strip perforation, and ledge formation. Reduces risks of metal fatigue and file fracture, minimizing postoperative adverse reactions and treatment failure rates.
• Efficient and User‑Friendly Operation: Compatible with a constant rotational speed of 260–360 rpm, featuring a torque protection mechanism. It saves time and simplifies operation, reducing clinicians’ workload.

Clinical Application

• SX: Flare the canal orifice.
• S1: Prepare the coronal and middle 1/3 of the root canal.
• S2: Prepare the middle segment and transition to the apical area.
• F1‑F3: Perform progressive fine preparation of the apical zone to complete root canal shaping.
