Filling technique - BackFill
Connect the BackFill gun (12) with the cable to the red socket (1f) of the device. The nut for
BackFill needle (9) must be tightened with the wrench (13) to avoid leakage of gutta-percha
at the thread. Form the needle with the tool’s forming rollers. Always make sure that the
needle is not bent or torn out of the connection base. Avoid bending back and forth. Press
the release (12a) and pull the piston (12b) backwards a little. Then insert only 1 pellet of
gutta-percha (14) into the upper opening of the gun for the time being. If the gun is already
heated, this should be done quickly to prevent the inserted material from sticking. Use the
lever (12c) to push the gutta-percha into the heating chamber with the help of the piston (12b)
and later through the needle. Make sure that the small screw and the seal at the end of the
piston (12b) are in place and firmly tightened. As long as the set temperature is not reached
and the gutta-percha is still hard, you should not press too hard to avoid damaging the gun.
If the heating times are longer, the gun’s outer parts will also be warmed up.
The bushing in the front area of the gun reaches temperatures of over 200°C. This is
necessary as a matter of principle, but requires careful handling.
Always use a heat thermal protector (11) to avoid burns. Always put on the thermal protector
shortly before application so that it does not heat up. Remove the thermal protector from the
gun after applying the gutta-percha. If necessary, change the protector during work to have
a cool thermal protector on the gun in each case. Check the heat of the thermal protector
(11) with your fingers before the application.
Do not touch the patient's lips or mucous membrane with the needle. During the filling
process, the needle should rise with the filling material.
Do not place the BackFill gun on electrically conductive surfaces. External voltages could be
transferred. Do not use the BackFill gun with the apex cable at the same time. Only use the
EndoPilot² holder for storage.
The use of excessive force may lead to breakage of the needle and to injuries. Always make
sure that the gun has been cleaned and prepared before each treatment. Use a new needle
in each case and a new gutta-percha pellet for each application.
After application, squeeze out any gutta-percha residue from the gun while the handpiece is
still hot. First unscrew the needle and pull the piston backwards out of the gun.
Only use original gutta-percha pellets. For information on dismantling, see the reprocessing
instructions.
