For dentists and endodontists, three keys to successful root canal treatments are efficiency, safety and reliability.
Technique is vital, as can be the file system you use. Technique and files often go hand in hand, with the best endo systems made to make root canal protocol as straightforward as possible.
An example of a file system designed for exactly this is the HyFlex EDM system and OGSF sequence from Coltene.
What are HyFlex EDM files?
HyFlex EDM (electric discharge machining) is a popular range of endodontic files for both standard and complex root canal procedures.
The files are manufactured from nickel-titanium (NiTi) alloy with Controlled Memory (CM) heat treatment.
This material, along with the EDM manufacturing process, is what make the files as durable and fracture resistant as they are.
Reasons to choose HyFlex EDM NiTi files
- Pre-sterile so immediately useable
- Highly flexible and pre-bendable
- Evenly, centred preparation reduces risk of ledging or perforation due to controlled memory effect
- Excellent fracture resistance and safety resistance thanks to unique hardened surface
- Variable cross-section design contributes to high breakage resistance
- Powerful cutting performance allows a smaller number of files for quick preparation
What is the OGSF sequence?
HyFlex EDM files are designed to be used in a sequence solution known as OGSF, an acronym made up of the first letters of each of the different files in the HyFlex EDM system.
The O stands for orifice opener, G for glidepath file, S for shaping file and F for finishing file.
The files are designed to be used in this defined order during treatment procedures to simplify preparation and shorten the learning curve for new dentists or when switching from a different system.
The OGSF sequence was developed to provide a smooth feeling when shifting from one file to another due to an optimised match of tip sizes and tapers. This helps you to keep control of the treatment.
Evidence has shown that by applying checklists and following standard protocols, reproduceable results and safety are improved, according to Coltene.
