TF4
High-quality NiTi reciprocating files with Gold heat treatment for enhanced flexibility and increased cyclic fatigue resistance. Designed for efficient root canal shaping with high cutting efficiency.
The TF4 Reciprocating Files are engineered for superior performance in root canal shaping. Made from Nickel-Titanium (NiTi) and enhanced with Gold heat treatment, these files provide exceptional flexibility and 50% more resistance to cyclic fatigue compared to conventional files.
The Gold heat treatment improves cutting efficiency while maintaining a high degree of elasticity, allowing the file to adapt to complex canal anatomies with ease. This reduces the risk of ledging, transportation, and file separation during procedures.
Intructions of use:
- Establish straight-line coronal and radicular access. Use a size #10 hand file to verify a glide path to length. Expand this glide path to at least 0.15 mm using either a manual or dedicated mechanical file, such as ET Files or the dedicated TF4 File.
- Initiate the shaping procedure with the PRIMARY file (#25/.07 Red) in the presence of sodium hypochlorite. Let the PRIMARY file passively progress through any region of the canal that has a confirmed glide path. After shaping 2-3 mm, remove and clean the PRIMARY file, then irrigate, recapitulate with a size #10 hand file, and re-irrigate. Continue in 2-3 passes to pre-enlarge the coronal two-thirds of the canal.
- Utilize a brushing motion on the outstroke to eliminate coronal interferences or enhance shaping results. In more restrictive canals, use a size #10 hand file with viscous chelator to negotiate to the terminus of the canal. Gently work the file until it is completely loose at length, then establish working length, confirm patency, and verify the glide path.
- Expand the glide path to at least 0.15 mm using a manual or mechanical glide path file. Carry the PRIMARY file to the full working length in one or more passes. Upon reaching length, remove the file to avoid over-enlarging the foramen.
- Inspect the apical flutes; if they are loaded with dentinal debris, then the shape is finished. If the PRIMARY file doesn’t progress, use the SMALL file (#20/.07 Yellow) in one or more passes to working length and then use the PRIMARY file again to optimize the shape.
- When the shape is confirmed, proceed with 3-D disinfection protocols. If the PRIMARY file is loose at length with no dentinal debris in the apical flutes, continue shaping with the MEDIUM file (#35/.06 Green) and/or LARGE file (#45/.05 White) until the apical flutes are loaded.
Incorporating TF4 Reciprocating Files into your endodontic workflow enhances efficiency, safety, and precision for successful root canal treatments.
