Common errors
- Forcing rotation against resistance
- Skipping a proper glide path
- Using a worn file on a second canal
- Ignoring cyclic fatigue after heavy use
Mishap Cases
Broken File — Straight Canal
4K-MSH-BF-SC
Simulates a separated instrument 3mm from the apex in a mid-straight canal. Teaches retrieval decision-making and bypass under anatomical constraints.

Mishap
3mm Mid-Canal
Why this model
Its clinical value.
File separation is the most feared intra-operative incident in endodontics. Training on a controlled straight canal first builds the retrieval instinct before facing curved anatomy.
Clinical context
How this model trains.
Training protocol
- Radiographic confirmation of the fragment position
- Straight-line access refinement
- Ultrasonic loosening of dentin around the fragment
- Bypass attempt with #08/#10 pre-curved K-file
- Decision: retrieve, bypass, or incorporate
Success criteria
- Fragment removed or bypassed without perforation
- Canal patency re-established to the apex
- No ledge created during retrieval
Learning outcomes
What the trainee learns.
- Ultrasonic retrieval technique
- Bypass with small K-files
- Clinical decision-making under pressure
