Mishap Cases
Models built for separated file retrieval, furcation perforation repair, ledge bypass, and troubleshooting under pressure.
4 models in this category
Broken File — Straight Canal
Simulates a separated instrument 3mm from the apex in a mid-straight canal. Teaches retrieval decision-making and bypass under anatomical constraints.
- Ultrasonic retrieval technique
- Bypass with small K-files
- Clinical decision-making under pressure
Broken File — Curved Canal
Separated instrument in a curved canal — the most clinically challenging retrieval scenario. Combines curvature management with mishap response.
- Curved canal retrieval strategy
- Risk assessment before and after separation
- Bypass in angulated anatomy
Furcation Perforation Model
A furcation area perforation requiring hemorrhage control, diagnosis confirmation, and MTA repair. Critical for teaching error management and repair workflows.
- Perforation detection and diagnosis
- MTA barrier placement technique
- Hemorrhage control protocol
Ledge Formation Model
A pre-formed ledge in the canal challenges learners to bypass, re-establish patency, and regain the working length without further damage.
- Ledge bypass with pre-curved files
- Tactile feedback recognition
- Restoring canal patency step-by-step
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.
