RETREATMENT TECHNIQUE
Establish a pilot hole using a small sized stainless steel handle with an appropriate solvent, heat carrier or ultrasonic instrument Without engaging dentin, gently press the spinning D1 into the obturated material.

Use D1 to remove the obturation material from the coronal 1/3.
Next, use the D2 to progressively remove material from the middle 1/3.
When appropriate, use the D3 to remove obturation material from the apical 1/3. Use hand files with a solvent to remove obturation materials from the apical 1/3 when encountering intricate anatomy.

Remove the frequently and inspect flutes. Continue as long as obturation material is visualized between the cutting blades.

Retreatment Files are available in 3 lengths, 3 progressive tapers and 3 apical diameters and are designed to remove root canal obturating material such as gutta-percha, carrier-based obturators, and fillers from coronal, middle and apical thirds of root canal prior to canal reshaping.

Designed to remove materials like gutta-percha, carrier and paste fillers, prior to reshaping procedures. The technique for removing a carrier core obturator or gutta-percha alone is the same.

RETREATMENT TIPS
• Always begin with a well-angulated set of radiographs.
• Understand the specific anatomy is critical to success.
• Obtain straight-line access to the canal.
• Assess the obturation material.
• Heat and friction will help remove the obturation material.
• Throughout the procedure, remove the instruments, inspect and clean the flutes. Then, re-insert and continue to auger material out of the canal.
• Recommended speed for Retreatment Files is 500-700 RPM
for gutta-percha and carrier based obturators. Use 300 PRM to remove paste fillers.
• Retreatment Files are single use devices.

Description

Post-treatment endodontic disease may occur due to the persistence of bacteria in the root canal system as a consequence of insufficient cleaning, untreated canals, inadequate filling, or coronal/apical leakage.
Non-surgical root canal retreatment is the first choice to re-establish healthy periapical tissues.
