Backfill
1.
Position the tip of the warm cannula against the previously packed
gutta-percha material for 5 seconds.
2.
Hold the Calamus
®
Flow handpiece lightly so it will back out of the
canal during use. Press the 360° activation cuff and dispense a small
2 to 3 mm segment of warm gutta-percha into this region of the
canal.
3.
Select the small, pre-fit Calamus
®
manual plugger and step its
working end circumferentially around the canal using short firm
strokes to clean the canal walls and flatten the dispensed warm
gutta-percha.
4.
Use the same small Calamus
®
manual plugger and press for 5
seconds to three dimensionally compact warm gutta-percha into this
region of the canal and to offset shrinkage during the cooling phase.
5.
Position the tip of the warm cannula against the previously packed
filling material for 5 seconds.
6.
Activate the Flow handpiece and dispense a little longer, 3 to 4 mm,
segment of warm gutta-percha into this region of the canal.
7.
Select the medium, pre-fit Calamus
®
manual plugger and step its
working end circumferentially around the canal using short, firm
strokes to clean the canal walls and flatten the dispensed warm
gutta-percha.
8.
Use the same medium Calamus
®
manual plugger and press for 5
seconds to three dimensionally compact warm gutta-percha into this
region of the canal and to offset shrinkage during the cooling phase.

Continue the backfill technique in the manner described, until the
canal is completely filled or to the required level if accommodating a
post for restorative needs.
