For restricted access canals:
If access to the canal opening is very restricted (i.e. by the opposing arch)
the metal pin may be pre-bent up to 90° for a better angle of insertion.
1. Remove the pin and handle from the plastic core by pulling it out with a
twisting motion.
2. Bend the metal insertion pin to the desired angle using wire bending
pliers. Allow at least 2 mm of pin for re-insertion into the core.
3. Re-insert the handle/insertion pin into the core.
4. Heat and insert the obturator in the usual manner.
Multi-rooted cases:
1. Obturate the smallest canal first.
®
2. Place absorbent points or HEROfill
Verifiers in the other canals prior to
obturation to prevent them being covered by gutta percha. Remove them as
each canal is obturated.
3. While there is sufficient gutta percha on each obturator to fill even the
most severe internally resorbed canal, it may be too much in some cases. If
it is obvious that there will be an excess of gutta percha for the canal, use a
sharp blade to trim some of the material from the coronal end of the
central core prior to heating.
In some cases it can be beneficial to remove the handle/metal insertion pin from
the actual plastic carrier, especially in multi-rooted teeth where the extra space
can make it easier placing the following obturators in the second and third canal.
Prior to heating of the obturator(s) as well as prior to marking of working length,
always assure that the handle/metal insertion pin can be separated from the
plastic carrier.
This is done by twisting the handle/metal insertion pin out of the plastic carrier.
Re-insert the handle/metal insertion pin into the plastic carrier.
You can now proceed to STEP 2.
