Why this case matters
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.
Training outcomes
- Canal fusion tracking technique
- Working length in fused anatomy
- Obturation adaptation at merge point
Common mistakes this model helps you avoid
- 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
Suggested 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
What a successful exercise looks like
- Single apical seal below fusion
- Preserved wall thickness
- No voids at the merge zone
