Summary
A new digital framework using CBCT and intraoral scanning offers predictable, minimally invasive treatment for root canal obstructions. It precisely locates canals and retrieves fractured posts, avoiding complications.
Area of Science:
- Dentistry
- Endodontics
- Digital Imaging
Background:
- Intracanal obstructions pose significant challenges in endodontic treatment.
- Previous methods for managing obstructions like fractured posts can be invasive and risk iatrogenic damage.
Purpose of the Study:
- To present a standardized, static-guided framework integrating Cone-Beam Computed Tomography (CBCT) and intraoral scanning.
- To demonstrate its efficacy in minimally invasive management of diverse intracanal obstructions.
Main Methods:
- A unified digital workflow combining CBCT and intraoral scanning was developed.
- The framework was applied to cases involving severe root canal obliteration and retrieval of fractured posts.
Main Results:
- The integrated digital workflow enabled precise localization of root canals, even in cases of severe obliteration.
- Conservative retrieval of fractured fiber posts and ultra-hard posterior zirconia posts was achieved without iatrogenic complications.
Conclusions:
- The standardized static-guided framework provides a predictable and minimally invasive approach for managing intracanal obstructions.
- This digital workflow enhances safety and precision in complex endodontic retrieval procedures.
