Double Curved Premolar · 4K-CRV-DC
Two sequential curvatures require strategic instrument sequencing, multi-angle radiographic analysis, and patience-based technique.

Why this case matters
Double curvature is the anatomy a single radiograph often hides. The model teaches you to plan from two angles and sequence instruments deliberately.
Training outcomes
- Multi-angle radiograph interpretation
- Sequential instrument strategy
- Controlled memory NiTi file use
Common mistakes this model helps you avoid
- 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
Suggested 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
What a successful exercise looks like
- Both curvatures preserved on bi-angulated films
- No ledge at the first curve
- Apex seal achieved without transportation
