Common errors
- Shaping both canals to the apex independently past the fusion
- Two separate apical stops where one exists
- Over-tapered post-fusion preparation
- Not verifying fusion location on films
Canal Variants
Type 2 — Fused Canal
4K-CNT-T2
Two separate canals merge into one before the apex. Teaches canal tracking from entry to fusion point and adapting obturation to the merged segment.

Why this model
Its clinical value.
Fused (Vertucci Type II) canals are the most common "hidden merge" in molars and premolars. Missing the fusion point leads to over-shaping and strip risk.
Clinical context
How this model trains.
Training protocol
- Size #10 patency in both orifices; recognise when one file path joins the other
- Shape both to fusion, then continue as single canal
- Single apical stop below fusion
- Oval-adapted obturation at merge zone
Success criteria
- Single apical seal below fusion
- Preserved wall thickness
- No voids at the merge zone
Learning outcomes
What the trainee learns.
- Canal fusion tracking technique
- Working length in fused anatomy
- Obturation adaptation at merge point
