• Packaging: Package of 3 Files

Twisted Files from Kerr are nickel titanium rotary endodontic files engineered with R-Phase technology for enhanced flexibility and resistance to cyclic fatigue. The R-Phase heat treatment maintains the NiTi alloy in a more flexible state at room temperature, reducing the risk of file separation during curved canal preparation. Unlike machined files, Twisted Files are physically twisted during manufacturing, preserving greater core strength while maintaining the flexibility needed for challenging canal geometries. The #25/.04 taper in 27mm length is suited for standard working lengths in anterior and premolar canal systems. Each package contains 3 files.

Key Features:

• R-Phase NiTi Technology: Heat-treated alloy provides superior flexibility over conventional NiTi files, significantly reducing cyclic fatigue and file separation risk in curved canals.
• Twisted Manufacturing Process: Physically twisted rather than machined, producing a file without traditional cutting flutes for improved core strength and fracture resistance.
• Size 25/.04 Taper: Standard taper suitable for initial shaping and final preparation of moderately sized canal systems.
• 27mm Length: Appropriate working length for anterior and premolar teeth requiring standard reach.
• 3 Files Per Package: Each package provides 3 files for convenient chairside availability across multiple procedures.
