Common errors
- Straightening the first curve into the second
- Using constant-taper files in variable anatomy
- Aggressive apical preparation that transports
- Skipping recapitulation between files
Curved Canals
S-Shaped Canal Premolar
4K-CRV-SS
The S-curve tests conceptual understanding before manual skills. Requires pre-curved files, crown-down approach, and WaveOne Gold or Reciproc Blue instruments.

Why this model
Its clinical value.
S-curves test conceptual understanding before hand skill. The instrument must be free to follow anatomy in two opposing directions within millimetres.
Clinical context
How this model trains.
Training protocol
- Small-taper variable-apex NiTi (e.g. TruNatomy, WaveOne Gold Primary)
- Balanced-force hand technique as backup
- Abundant EDTA lubrication
- Recapitulate to patency with #10 after each shaping file
- Warm vertical obturation for adaptation
Success criteria
- Both curves visible on final film
- No strip perforation at inflection point
- Three-dimensional seal
Learning outcomes
What the trainee learns.
- S-curve conceptual anatomy
- WaveOne Gold / Reciproc Blue technique
- Warm vertical compaction in complex canals
