Summary
A novel endodontic template provides a precise, guided method for removing fiber posts during root canal retreatment. This technique ensures conservative access and successful obturation, improving patient outcomes.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Fiber posts are commonly used for core retention in endodontically treated teeth.
- Failure of endodontic treatment may necessitate retreatment, including fiber post removal.
- Conventional fiber post removal can be challenging and may lead to procedural complications.
Observation:
- A 40-year-old male presented with apical periodontitis around a maxillary left canine with a retained fiber post.
- A fully guided, conservative approach using a 3D-printed endodontic template was employed for fiber post removal.
- Cone-beam computed tomography (CBCT) and cast surface scan data were merged for virtual planning and template fabrication.
Findings:
- The endodontic template accurately guided the drilling process, enabling conservative removal of the fiber post.
- Access to the root canal was achieved without damaging the coronal tooth structure.
- Successful root canal retreatment was performed, followed by obturation and temporary restoration.
Implications:
- This guided template technique offers a predictable and conservative alternative for fiber post removal in endodontic retreatment.
- It minimizes the risk of procedural errors and preserves tooth structure.
- The method has the potential to improve success rates for complex endodontic retreatment cases.
