Area of Science:

Endodontics
Dental Technology

Background:

Separated instruments in root canals impede chemo-mechanical preparation and compromise prognosis.
Guided endodontics presents a highly predictable technique for fractured instrument retrieval.

Observation:

A case report details the retrieval of a fractured instrument in a previously treated tooth with symptomatic apical periodontitis.
The patient presented with tooth discoloration and pain, with radiographic evidence of poor obturation and a middle-third root canal fracture.

Findings:

Cone beam computed tomography (CBCT) and intraoral scans were utilized to generate DICOM and STL files.
These files were merged using specialized software to create a virtual drill path for fabricating a 3D acrylic guide.
The guided endodontic approach facilitated the successful retrieval of the fractured instrument.

Implications:

This stepwise approach demonstrates the efficacy of guided endodontics for complex root canal treatment scenarios.
The integration of CBCT and 3D printing enhances precision and predictability in endodontic surgery.
Guided endodontics provides a reliable method for improving treatment outcomes in cases of separated instruments.
