01 According to the prepared root canal, choose a proper chief gutta-percha tip.
02 Choose proper tip for Heating and Packing Instrument, place the tip into the root canal and keep it 4-7mm away from the apical foramen, and use a pad to mark the length. At the same time, choose a plugger of the same size.
03 Dip the sealing material with the chief gutta-percha tip, and then put that gutta-percha tip into the root canal.
04 Put the tip of Heating and Packing Instrument into the root canal, press heating button for heating, cut off the redundant part of gutta-percha and take it out.
05 Put the tip into the root canal, press heating button for heating, and push the tip to soften the gutta-percha until the tip reach a place where is 4-7mm away from the apical foramen. (Do not heat up for more than 3s. Meanwhile, keep the tip moving while heating and avoid heating at a certain part for a long time, or it is likely to scalding the root canal.)
06 Release the heating button to stop heating, but keep pressing the gutta-percha in the root canal with tip for about 10s.

07 Press heating button for about ls, and rapidly take out the gutta-percha 4-7mm away from the apical foramen.

08 Use plugger to impact the gutta-percha in the root canal.
09 Get the needle of Hot Melting and Filling Gun touch the surface of gutta-percha in the root canal, and stay there for 3s to soften the gutta-percha.

10 Inject the melted gutta-percha into the root canal, and withdraw the needle at the same time. (Do not fully fat the root canal at only one time. It is recommended to fill it in 3 times, or a single injection should not exceed 4mm.)
11 Use plugger to impact the injected gutta-percha in the root canal.
12 Repeat Step 9 to Step 11 until the root canal filling is finished.
