Clinical Tips
- HyFlex GPF files use 500 RPM and up to 2.5 Ncm torque (per HyFlex family brochure and summary). Any continuous-rotation endodontic motor may be used.
- The three-file sequence (Navigator NT 15/.01, CM K File 15/.02, CM K File 20/.02) establishes a smooth glide path from initial scouting to #20/.02.
- CM K Files have controlled memory properties, allowing them to track canal anatomy closely without shape memory rebound.
- The Navigator NT file is an NiTi file (not CM-Wire), while the two CM K Files use CM-Wire technology.
- Reusable files; shape regenerates during autoclaving. Visual inspection after autoclaving serves as a discard indicator.
- Available in 21 mm, 25 mm, and 31 mm lengths, as well as assorted packs.
Warnings
- Reusable instrument; inspect before and after every use for visible changes in material or shape
- If spirals rewind in the opposite direction during use, the file is plastically deformed; discard immediately
- If spirals remain lengthened after autoclaving, the file should be discarded
- Do not use on patients with known nickel or titanium allergy
- Contains nickel-titanium; follow manufacturer reprocessing instructions
- HyFlex GPF does not have a separate product page; specifications are carried by HyFlex family brochures
