Explain Ledge bypass - Non-surgical Endodontic Retreatment
Ledge bypass - StSt not NiT cause it has shape memory
- Ledges from outside the curvatures.
- The file tip is slowly scraped along the internal wall of the canal curve slightly coronal to the level of the ledge.
- Looking for another sticky spot that indicate the entrance to the apical canal segment.
- Gentle reciprocal rotation allow the file to negotiated to the canal terminus.
- Confirm with a radiograph.
- Short-amplitude push/pull and rotational forces.(not more than 1 mm )
- Anti-curvature filing to blend the ledge.
