9. Heating GUTTACORE
For details on the use of the obturator oven, please refer to THERMAPREP
Manual.
For an optimal use the GUTTACORE
10. Placing the Obturator in the Canal
After the first signal "beep" of the THERMAPREP
obturator holder and guide the holder with your finger. Take the obturator carefully out of the holder by
first lifting it up a little and then pulling it toward you. The oven will "beep" every 15 seconds to remind
you that the obturator is still in the oven. After 90 seconds, the oven will switch off automatically. Insert
®
GUTTACORE Obturator directly into orifice of canal.
Avoid touching the walls of the occlusal opening.
We strongly recommend not to wait more than one "beep" for an optimal use of the GUTTACORE
Obturator.
Note: If the canal has been properly shaped and the gutta-percha properly heated, the obturator should
seat to place without twisting or forcing. To avoid overextension, don't force the GUTTACORE
beyond the working length. You will note a backflow of sealer and gutta-percha resulting in an
accumulation at the orifice. This is to be expected, especially in multi-rooted teeth, because the obturator
is designed with excess gutta-percha to accommodate event the most widely flared or anatomically
irregular canals.
11. Removing the GUTTACORE
Remove the shaft and handle at the orifice by bending to either side of the canal wall. Alternatively, while
stabilizing the GUTTACORE
in a high-speed handpiece, or use a sharp spoon excavator. Dispose of obturators in an appropriate
biohazard container.
12. Compacting Gutta-Percha in Large, Oval or Irregular Shaped Canals
Insert a small segment of conventional gutta-percha, 4 – 6 mm long, alongside the shaft of the
®
GUTTACORE Obturator with a lubricated plugger and compact. The gutta-percha segment compacts
the heat softened gutta-percha and becomes an integral part of the filling. This will also prevent
inadvertent removal of gutta-percha from the orifice with an inadequately lubricated plugger, as well as
compensate for the lack of gutta-percha in uncommonly large canals or those with internal resorption
defects. Due to the tacky nature of the plasticized gutta-percha, you must use a lubricant such as GLYDE
®
File Prep root canal conditioner, sealer, topical anesthetic, etc., on the plugger.
13. Removing Excess Gutta-Percha
Clean the canal chamber using a spoon excavator, explorer, etc., to remove any excess gutta-percha
that may block access to the chamber and other canals. Repeat all of the above steps on each canal of a
multi-rooted tooth. If necessary, protect adjacent canal orifices from debris and gutta-percha with tiny
cotton pellets or a paper point until time for obturation. Obturation is complete once excess gutta-percha
is removed.
14. Create an occlusal leakage barrier with a composite restorative to help prevent contamination
of the root canal system.
15. Removing GUTTACORE
Creating post space and retreating are accomplished using traditional methods for removing obturation
material.
For creating post space, remove the GUTTACORE
Space Bur.
When removing the obturation material for retreatment purposes, use the same size rotary file used for
shaping and engage the obturation material (a non-landed rotary file is preferable).
