Non-surgical re-treatment is often the first option for re-treating teeth with post endodontic treatment disease or complications.
Exact Retreatment files are designed to remove materials such as gutta percha, carrier-based obturators and other filling materials from the coronal, middle and apical thirds of the root canal prior to canal re-shaping and filling.
Retreatment Technique
-
Establish a pilot hole using a small sized stainless steel hand file 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 files frequently and inspect flutes. Continue as long as obturation material is visualized between the cutting blades.
Retreatment Tips
-
Always begin with a well-angulated set of radiographs.
-
Understand the specific anatomy is critical to success.
-
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 EXACT Retreatment Files is 500-700 RPM for gutta-percha and carrier based obturators. Use 300 PRM to remove paste fillers.
