Staying on PATH with STRENGTH and INFINITE FLEX

Without question, NiTi endodontic files revolutionized root canal therapy almost two decades ago. The flexibility of traditional NiTi files were a great improvement over stainless steel files, allowing curved canals to be addressed easily. Further, the advent of rotary handpieces used with NiTi files formed the armamentarium of choice for virtually every endodontist and a large percentage of general dentists.

Also without question, NiTi files and rotary handpieces have shortcomings, most commonly file separation and over instrumentation of the canal. These, in fact, are why some general dentists choose against rotary driven endodontics in their practices. At CLINICIAN’S CHOICE®, we understand your common endodontic clinical challenges, and we focus our product development on solving these challenges. We are proud to introduce a significant technological and clinical advancement for endodontic therapy – TYPHOON™ Infinite Flex NiTi Files.

Infinite Flex without the memory
TYPHOON Infinite Flex NiTi files are constructed with revolutionary CM Wire™ (patent pending), which exhibits virtually no memory. While traditional NiTi files are flexible, they will always try to straighten when flexed within a canal. This causes unbalanced lateral forces along the canal wall and often results in ledging as well as excess tooth structure being removed unnecessarily. When you choose memory-free TYPHOON files, the lateral forces are balanced throughout the length of the file (we call this Infinite Flex). Canal navigation is effortless, regardless of the curvature of the canal, because TYPHOON files adapt perfectly to the canal path for precise and conservative removal of tooth structure.

Aggressive and safe

Cyclic fatigue and torsional stress are the two primary causes of file separation. The inherent memory of traditional NiTi files accentuates torsional forces and promotes cyclical fatigue. In the past, the more aggressive cutting ability of a NiTi file has always corresponded to a higher propensity for file separation due to stress points created along the file. Not any more!

A recently-published university based study directly compared TYPHOON files with ProFile (Dentsply Tulsa Dental, Tulsa, OK), TYPHOON files proved to be at least 300% more resistant to fatigue stress. TYPHOON files do cut aggressively, but thanks to memory-free CM Wire, they have up to three times the torsional strength, so the risk of separation is dramatically reduced. With TYPHOON, you’ll experience cutting far superior to what you are accustomed, and you’ll gain significantly more confidence, especially in cases with curved canals. 

Better access for posterior teeth
Here’s one more significant clinical advantage: TYPHOON files can be pre-curved to allow easier canal access in posterior teeth. Bend the file just as you would a stainless steel file. You’ll be in for a pleasant surprise, because you certainly can’t do this with traditional NiTi files!
 
Choosing your file size and sequence

While several different instrumentation sequences are possible, the following is suggested for most canal shapes: 35/.06 > 30/.04 > 25/.06 > 20/.04.

You’ll get the best results from cycling back through the sequence until the desired coronal and apical shape is achieved. The advantages of filing in this manner are far-reaching. First, alternating tapers will help you to avoid “taper lock”, and you can shape the canal with only instruments. Perhaps most important, this sequence achieves adequate apical shape without sacrificing undue middle and coronal tooth structure

More tips for your next endo case:
Establish a glide path first with hand files up to at least a 15, or a #10 hand file, followed by X-PLORER rotary files 15/.01, 20.02.
You may wish to use a chelating/file lubricating agent, such as FileEze (Ultradent).
Irrigation with sodium hypochlorite should be repeated throughout the shaping process. High volume and frequent exchange are recommended. 
Throughout the procedure, maintain canal patency using hand instruments.
Clean the file after each and every insertion.
Use a light touch. Never force the instrument apically.
Recommended handpiece speed:  400 RPM
Torque: 200-275 GCM for all sizes

  1. MAKE ENDO EASY

    Posted by Dr.Elaine Sides on 19th Sep 2011

    I am a general dentist and have been using rotary files for over 15 years and TYPHOON files are not only easy to use and effecient but I was surprised at how quickly I finished my canal preparation - so was my assistant. The canal was smooth and clean. I do over 5+ posterior root canals each week and it was the same each and everytime.I am not going to use any other sytem. There was no unwiding of the file and I can pre-curve them - now that is terrific. All of you must try these - they are fabulous.
