The ESX Rotary File® from Brasseler USA® is equipped with a patented ACP™ (alternating contact point) design that efficiently cleans 3 dimensionally as its sharp cutting edges engage with the canal walls at opposing intervals. The asymmetrical flute design alternates between zero to three points of engagement while moving debris coronally in a wave-like motion. This mechanism allows the ESX to operate at a low torque setting yet at a higher speed, reducing stress on the file and root. In addition, the triangular cross section of the ESX Rotary File supports sharper cutting edges and a larger chip space for more effective debris removal.
As with all Brasseler USA rotary files, the ESX Rotary File surface is treated with Brasseler’s exclusive proprietary electropolished finish. The electropolished treatment greatly improves resistance to cyclic and torsional fatigue often associated with the long-term use of dental rotary files.
Another significant feature of the new ESX Rotary File is its patented booster tip. The BT Tip™ maximizes safety and efficiency and provides the user stress-free apical progression and clearing of debris while respecting even the most challenging canal anatomy. The BT Tip features six cutting edges that smoothly transition to a true reamer design for increased cutting efficiency, and has an anti-ledging and anti-perfing centering mechanism that provides superior performance each and every time.
