A Chi-square test showed that the deformation curve: Sign In You need to be signed in to order items. Follow Dental Directory on: Please review our privacy policy. Discussion At the beginning ofa series of studies 12 – 15 found that changes in the transformation behavior via heat treatment were effective in increasing the hiti of NiTi endodontic instruments.

The data were analyzed using Nitk and t -test. 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.

Influence huflex rotational speed, torque and operator’s proficiency on ProFile failures. Influence of structure on nickel-titanium endodontic instruments failure. Author information Article notes Copyright and License information Disclaimer.

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. Defects in nickel-titanium instruments after clinical use. Mechanical properties of nickel-titanium rotary instruments produced flles a new manufacturing technique.


J Int Oral Health. Comparison of defects in profile and protaper systems after clinical use. Furthermore it will strengthen the files making them a lot more resistant to cyclical fatigue. An overview of nickel-titanium alloys used in dentistry.

Hyflex CM NiTi Files 25mm 06/20

Footnotes Source of Support: 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. A series of proprietary thermomechanical processing procedures has been developed with the objective of producing SE NiTi wire blanks that contain substantially stable martensite phase under clinical conditions.

This gives the file the ability to follow the anatomy of the canal very closely, reducing the risk of ledging, transportation or perforation.

File scanned image after autoclaving restored the original shape. Ninan E, Berzins DW. 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.

Topographic Analysis of HyFlex® Controlled Memory Nickel–Titanium Files

Furthermore, many studies showed the new CM-wire manufacturing process to produce NiTi rotary instruments that were more flexible and more resistant to cyclic fatigue than instruments produced by a traditional manufacturing process or a thermally treated NiTi alloy M-wire.

Proprietary processes are highly influenced by temperature and time intervals, and each small change makes every manufacturing process unique. Also it provides a clear visual opportunity to yyflex safe continuation of file use. These files respond to pressure, torque, and resistance with a lengthening of the spirals, and, therefore, increases the fracture resistance.

Hyflex CM Memory File

Since then, heat-induced or heat-altering manipulations were used ciles influence or alter the properties of NiTi endodontic instruments.

It was observed that most of the files hyfflex defects that appeared as lengthening of the spirals due to the unwinding without fractures. The defects for each file after use and after autoclaving were recorded. Read our privacy policy for more information. Torsion and bending properties of shape memory and superelastic nickel-titanium rotary instruments. Before the initial scans were performed, a customized jig was fabricated, and filse file was mounted such that it could be placed in the same position before and after use.


Only 4 files showed slight defects at the tips of the files. This website uses cookies. Particularly in root canals with abrupt curvatures this can help avoid the cn of steps.

File scanned image after use showed visible defects, combined defects unwinding and curving. Received May 10; Accepted Aug National Center for Biotechnology InformationU. This is an open-access article distributed under the terms of the Creative Commons Attribution-Noncommercial-Share Alike 3.

The manufacturer reports that the shape and strength of files with straightened spirals can be restored during autoclaving, 11 meaning that the files appear to regain their shape after sterilization and reuse. Support Center Support Nifi.
