It was observed that most of the files showed defects that appeared as lengthening of the filex due to the unwinding without fractures. These changes were categorized according to the severity as follows:. CM NiTi files have been manufactured using a special thermomechanical process that controls the memory of the material, making the files extremely flexible but without the shape memory of other NiTi. Order up until 6pm.

Fatigue testing of controlled memory wire nickel-titanium rotary instruments. Effect of environment on fatigue failure of controlled memory wire nickel-titanium rotary instruments.

Comparison of cyclic fatigue resistance of novel nickel-titanium rotary instruments. Proprietary processes are highly influenced by temperature and time intervals, and each small change makes every manufacturing process unique. Only 4 files showed slight defects at the tips of the files. Introduction A major innovation in endodontics has been the introduction of nickel-titanium NiTi alloy to manufacture root canal instruments, mainly due to the superelasticity of the NiTi alloy, which provides increased flexibility and allows the instruments to effectively follow the original path of the root canal.

Factors influencing defects of rotary nickel-titanium endodontic instruments after clinical use. File scanned image after autoclaving restored the original shape. Almost all of the used files exhibited significant visible defects without fractures, including unwinding and curving associated with unwinding. Three-dimensional analysis of root canal geometry by high-resolution computed tomography.

However, the majority uyflex these files could be restored after autoclaving. Ninan E, Berzins DW.

HyFlex™ CM NiTi Files

Therefore, with the limitations of this study, it can be concluded that the shape of files with unwound spirals can be restored during autoclaving. Author information Article notes Copyright and License information Disclaimer. Since then, heat-induced or heat-altering manipulations were used to influence or alter the properties hydlex NiTi endodontic instruments.


Footnotes Source of Support: These changes were categorized according to the severity, and the initial and final scans of the files were superimposed to illustrate the recovery of the files to their original shape. Used files were wiped and placed in file blocks, to avoid any contact between instruments. CM NiTi files are unlike conventional files that exhibit a stress-induced phase transformation; instead, these files show behavior that is similar to what is termed martensitic-active or shape memory, which produces remarkable fatigue resistance.

Before the initial scans were performed, a customized jig was fabricated, and each file was mounted such that it could be placed in the same position before and after use.
