The explanation for this phenomenon may be that heating transforms the metal temporarily into the austenitic phase, which makes it possible for the hyflrx to regain its original shape before cooling down again.

National Center for Biotechnology InformationU. 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. Received May 10; Accepted Aug Ninan E, Berzins DW. A Chi-square test showed that the deformation curve: 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.

Irrigation with distilled water was performed frequently when using the files. Open in a separate window.

This is consistent with the view that NiTi files do not present the rebound effect after unloading, and their original shape is restored only after autoclaving.

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 flexibility of NiTi endodontic instruments.

Factors influencing defects of rotary nickel-titanium endodontic instruments after clinical use.

Only 4 files showed slight defects at the tips of the files. Influence of structure on nickel-titanium endodontic instruments failure.


HyFlex Rotary Files

Furthermore the files can be pre-bent, similar to the way of stainless steel. Articles from Journal of International Oral Health: This gives the file the ability to follow the anatomy of the canal very closely, reducing the risk of ledging, transportation or perforation.

Almost all of the used files exhibited significant visible defects without fractures, including unwinding and curving associated with unwinding. Also it provides a clear visual opportunity to verify safe continuation of file use. An overview of nickel-titanium alloys used in dentistry. 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.

File scanned image after autoclaving restored the original shape. Access cavities were prepared on 12 plastic teeth using 2 and 4 high-speed round carbide burs Dentsply-Maillefer, Ballaigues, Switzerland. Since then, heat-induced or heat-altering manipulations were used to influence or alter the properties of NiTi endodontic instruments. Furthermore it will strengthen the files making them a lot more resistant to cyclical fatigue.
