Kerr SybronEndo Twisted File (TF) – .04 Taper, 23mm Refill (SKU: W-822-4253)

Primary Clinical Application: Apical Finishing in Curved Canals

This .04 Taper Twisted File is an essential instrument for the final stages of root canal preparation, particularly in challenging, curved anatomies. Its conservative taper allows you to safely and precisely shape the apical third of the canal to the desired size without removing excessive dentin coronally. This preserves the natural anatomy and strength of the root, reducing the risk of transportation or stripping.

The Twisted File Advantage: Flexibility Where It Counts
The unique twisted manufacturing process gives the TF file unparalleled flexibility. This is most critical in the apical third, where the file must negotiate curves without straightening the canal. The .04 Taper TF file follows the natural path with ease, leading to a more anatomically correct and successful preparation.

Key Features & Benefits:

• Ideal for Curved Canals: The combination of high flexibility and a conservative taper makes it the go-to file for finishing challenging molar roots.
• Preserves Root Structure: The .04 taper is minimally invasive, protecting the integrity of the tooth and improving its long-term prognosis.
• Precise Apical Finishing: Delivers a clean, well-shaped apical seat that is ready for predictable 3D obturation.
• Superior Fracture Resistance: The R-Phase™ heat treatment and twisted design provide peace of mind against file separation during the most delicate phase of shaping.
