In the squares, there a conditions or situations where a clinical decision needs to be made. The circles represent uncertainty after a decision and action. Condition in italics represent final outcomes where no further clinical decisions need to be made. The other end-points may require further decision making.


"Whether simple or complex root canal anatomy, almost all clinical cases can be treated with one sequence. The file dimensions (tip size and taper) are perfectly coordinated. I have everything under control, and the success is predictable."

"With just a few peckings, I reach the measured working length without any stops in between, so to speak. Previously, a file had to be inserted into the root canal several times. That is no longer necessary here! The OGSF sequence can be applied effortlessly even in difficult cases."

HyFlex File Technologies

HyFlex EDM

Outstanding fracture resistance

HyFlex EDM files have a special surface and are characterized by their durability and high fracture resistance which they owe to the innovative “Electric Discharge Machining” manufacturing process.

HyFlex CM

High fracture resistance and pre-bendable

Once manufactured using the EDM process, the HyFlex files are then heat treated with a CM (Controlled Memory) process. This process gives the files the properties to be pre-shaped prior to use, to allow access to the even the most difficult of canals.
