1. When using the Endo Motor To control the torque and speed, it is best to set the torque control motor and the matching speed. Following the torque recommended by the expanded needle manufacturer, speed is particularly important for treatment safety.
2. Measure the length of the instrument each time it enters the root canal. Longer instruments increase the risk of twisting and breaking. Equipped with root canal length measuring instrument, caliper, etc. for working length measurement.
3. Correct operation is very important: do not apply pressure and force on the tip. The instrument should not stay in the root canal for too long.
4. The breakage of the device mostly occurs in molars, especially in the narrow and narrow root canals such as the upper canal and mandibular molars. The mesial root canal should be treated with great care before treatment.
5. Curved root canals, re-treatment, and calcified root canals require special equipment and techniques, and it is best to use new expansion needles.
6. Establish a straight path to maintain a smooth root canal, pay attention to gestures during operation, and try to ensure that the expansion needle and the root canal path are in line to reduce the bending resistance of the expansion needle in the crown and the stress on the instrument.
7. The root canal should be kept sufficiently lubricated and should be rinsed every time it is prepared.
8. Because the internal root canal is narrow, do not apply pressure to the expansion needle during operation. The cutting should be completed solely by the strength of the machine itself and the sharp edge of the expansion needle.
9. In the case of insufficient experience, it is safest to use the recommended minimum torque. Generally speaking, lower speed will extend the clinical life of the device and reduce the chance of breaking.
10. Choose a good expansion needle and control the number of times of use: when using it, you should observe whether there is drawing or deformation. If you find it, you must discard it in time, but you will regret it.
11. After each use, it is best to record the number of uses to prevent fatigue of the instrument; the debris of the expanded needle edge should be cleaned repeatedly in time and equipped with a cleaning table.
