HyFlex Rotary Files

Author information Article notes Copyright and License information Disclaimer. These files respond to pressure, torque, and resistance with a lengthening of the spirals, and, therefore, increases the fracture resistance. At the beginning ofa series of studies 12 – 15 found that changes in the transformation behavior via heat treatment were effective in increasing the flexibility of NiTi endodontic instruments.

File scanned image after use showed visible defects, combined defects unwinding and curving. Ninan E, Berzins DW. The explanation for this phenomenon may be that heating transforms the metal temporarily into the austenitic phase, which makes it possible for the file to regain its original shape before cooling down again.

Effects of four Ni-Ti preparation techniques on root canal geometry assessed by micro computed tomography. Since then, heat-induced or heat-altering manipulations were used to influence or alter the properties of NiTi endodontic instruments. National Center for Biotechnology InformationU. Defects in nickel-titanium instruments after clinical use.


Surface analysis was performed for each file to determine the changes in the files after deformation; defects were recorded as unwinding and curving associated with unwinding Figure 2. Particularly in root canals with abrupt curvatures this can help avoid the creation of steps.
