Guided Endodontics as a Personalized Tool for Complicated Clinical Cases

Area of Science:

• Endodontics
• Digital Dentistry
• 3D Printing

Background:

• Root canal calcification, caused by tertiary dentin deposition, presents significant challenges in endodontic treatment.
• Post-traumatic pulp canal obliteration (PCO) and calcification in elderly patients complicate root canal localization.
• Digital dentistry offers innovative solutions for complex endodontic cases.

Observation:

• A technique using a digitally planned, 3D-printed endodontic guide was developed for precise root canal localization.
• The workflow integrates cone-beam computed tomography (CBCT) imaging with intraoral scans for template design.
• The 3D-printed guide, made from transparent resin, directs the endodontic tool during root canal treatment (RCT).

Findings:

• The guided endodontic access approach facilitates minimally invasive RCT, preserving tooth structure.
• This method improves the predictability of locating root canals, even in severely calcified or obliterated systems.
• The use of the guide helps avoid iatrogenic complications during endodontic procedures.

Implications:

• Navigated endodontics with 3D-printed guides enhances treatment outcomes and prognosis.
• This technology represents a significant advancement in managing challenging endodontic cases.
• The technique offers a more predictable and less invasive alternative for root canal treatment.
