Specialized and adapted NiTi file systems for removing existing root canal fillings and re-shaping canals. Retreatment-specific instruments, techniques, and cross-compatible systems.

 8 systems

Retreatment cases require instruments capable of removing gutta-percha, carrier-based obturations, and bioceramic sealers while preserving remaining tooth structure. The systems below include dedicated retreatment files (such as D-files and XP-endo Retreatment) as well as primary shaping systems whose manufacturers have published retreatment protocols. Alloy flexibility and active tip design are key selection criteria for safe navigation through previously instrumented canals.
