STEP-BY-STEP INSTRUCTIONS
6.5.2 Downpack: Continuous Wave Technique
1. Activate the electric heat plugger and sear off the master cone at the
level of the orifice.
2. Select the larger manual plugger and step its working end around
the circumference of the canal using short, firm strokes to move
gutta-percha apically, clean the canal walls and flatten the material.
3. Use this larger manual plugger and press for five seconds to compact
warm gutta-percha vertically and laterally into this region of the root
canal system (first wave of condensation).
4. Activate the electric heated plugger and, in one deliberate
and continuous motion, press the heated plugger through the
thermosoftened gutta-percha until the silicone stop is 2mm from the
reference point. This procedure must be limited to two to four seconds
to prevent thermal injury.
5. Deactivate the plugger and continue to maintain firm apical pressure
on the cooling instrument until the silicone stop reaches the reference
point.
6. Maintain firm apical pressure for ten seconds to compact the mass of
warm gutta-percha into the apical one-third of the root canal system
and to offset shrinkage during the cooling phase.
7. Activate the electric heated plugger for one second, then deactivate
and remove the plugger from the root canal using a back and forth
motion. This procedure separates and removes gutta-percha from the
coronal two-thirds of the canal without disturbing the gutta-percha in
the apical one-third.
8. Select the small manual plugger and step its working end around the
circumference of the canal using short, firm strokes to clean the canal
walls and re-condense the most coronal aspect of the gutta-percha
within the apical one-third.
9. Use Flow hand piece to optimally fill the rest of the canal.
