Why it matters for dental

Endodontists and general dentists treating calcified canals can expect measurable gains in accuracy and reduced chair time by adopting guided-access techniques that use 3D-printed models, potentially improving case acceptance and lowering perforation risk.

Key points

  • The study compares four distinct guided-access protocols on a novel 3D-printed model designed to simulate calcified canals.
  • Published in the Journal of Endodontics, August 2026, the findings provide peer-reviewed benchmarks for accuracy and efficiency that clinicians can cite when discussing treatment options with patients or insurers.
  • Because the model is 3D-printed, practices already using in-office printing or outsourcing labs can replicate the workflow without purchasing proprietary hardware.
  • Improved canal-location rates translate directly to fewer referrals, higher procedure revenue retention, and reduced risk of missed canals that lead to retreatment.
