Common errors
- Attempting rotary retrieval inside a curve
- Over-enlarging the outer curve and thinning the canal wall
- Skipping CBCT when available
- Pushing the fragment apically while probing
Mishap Cases
Broken File — Curved Canal
4K-MSH-BF-CC
Separated instrument in a curved canal — the most clinically challenging retrieval scenario. Combines curvature management with mishap response.

Why this model
Its clinical value.
File separation in a curved canal is clinically the hardest retrieval scenario. The fragment often sits exactly where curvature peaks, removing most tolerance for error.
Clinical context
How this model trains.
Training protocol
- CBCT (when available) to map fragment relative to curvature
- Straight-line access exaggerated to the coronal third
- Microsurgical ultrasonic tip under magnification
- Bypass with ultra-flex pre-curved 08 file
- Reassess every 2 minutes; stop if thinning is suspected
Success criteria
- Either clean retrieval or safe bypass preserving wall thickness
- Working length restored
- No strip perforation on the danger zone
Learning outcomes
What the trainee learns.
- Curved canal retrieval strategy
- Risk assessment before and after separation
- Bypass in angulated anatomy
