Common errors
- Reading the canal as a single curve
- Using a stiff file past the first curve
- Skipping intermediate-size glide path
- Ignoring angulated second-radiograph findings
Curved Canals
Double Curved Premolar
4K-CRV-DC
Two sequential curvatures require strategic instrument sequencing, multi-angle radiographic analysis, and patience-based technique.

Why this model
Its clinical value.
Double curvature is the anatomy a single radiograph often hides. The model teaches you to plan from two angles and sequence instruments deliberately.
Clinical context
How this model trains.
Training protocol
- Bi-angulated pre-op radiographs
- Straightline access with buccal offset
- Hand-file glide path to #20 before rotary
- Controlled-memory NiTi in apical third only
- Post-op radiographs from two angles
Success criteria
- Both curvatures preserved on bi-angulated films
- No ledge at the first curve
- Apex seal achieved without transportation
Learning outcomes
What the trainee learns.
- Multi-angle radiograph interpretation
- Sequential instrument strategy
- Controlled memory NiTi file use
