So Sophisticated, It’s Simple
THE PATENTED* ACP™ (ALTERNATING CONTACT POINT) DESIGN
- Efficiently cleans 3 dimensionally as the sharp cutting edges engage with the canal walls at opposing intervals.
- Asymmetrical flute design alternates between zero to three points of engagement.
- Moves debris coronally in a wave-like fashion.
- Allows ESX to operate at a low-torque setting and higher speed, thereby reducing stress on the file and root.
- The restoration of an endodontically treated tooth begins at the apex.
- The cleaning and shaping instruments should be minimally invasive and preserve the structural integrity of the tooth.
- The obturation materials should bond to the root canal walls, thereby strengthening the root.
- When a post is necessary, it should not put undue stress on the root. It should have a similar modulus of elasticity to that of dentin and it should match the shape created by the last instrument used to shape the canal.
- The system should be as safe and efficient as possible and every component should be designed to maximize the long term prognosis of the tooth.
ESX®: TWO-FILE SHAPING SYSTEM
- Unlike other “simplified” file systems which utilize from one to three files, the ESX® system does not suggest that the practitioner finish specific canals to a pre-determined size. A “cookie cutter” approach can lead to under-and-over-preparation of canals.
- The ESX® system utilizes the Expeditor™ file (#15/.05) to help the practitioner select the appropriate final apical size for each canal based on its unique anatomy.
- Unlike other systems, the ESX® system is designed to preserve the maximum amount of coronal tooth structure, thereby maximizing the long-term prognosis of the tooth.
- Use all ESX® files at 500-600 RPM with a torque setting of 1.5-2.3 Ncm.
- Use a “LIGHT TOUCH” and the “SINGLE STROKE AND CLEAN” technique.
- ESX® Expeditor™ File – Provides initial shaping and helps determine the appropriate finishing file for each canal using the following guidelines:
- Significant engagement to obtain WL = Finish with ESX® Small File #25/.04*
- Moderate engagement to obtain WL = Finish with ESX® Medium File #35/.04
- Minimal engagement to obtain WL = Finish with ESX® Large File #45/.04
- No engagement to obtain WL = Finish with ESX® Extra-Large File #55/.04
