Area of Science:

Endodontics
Dental Microsurgery
Medical Navigation Systems

Background:

Endodontic microsurgery is crucial for natural tooth preservation.
Operator skill significantly impacts outcomes, especially in challenging anatomical locations.
Dynamic Navigation Systems (DNS) offer potential for enhanced accuracy and efficiency in endodontic microsurgery.

Purpose of the Study:

To compare the clinical outcomes of endodontic microsurgery performed with a dynamic navigation system (DNS) versus the freehand technique.
To evaluate the efficiency, accuracy, and patient-reported pain associated with DNS-guided endodontic microsurgery.

Main Methods:

A randomized study involving 16 patients, divided into DNS-guided and freehand groups.
Procedures assessed include osteotomy and root-end resection.
Outcome measures include procedure time, Visual Analogue Scale pain scores, cone beam CT-derived deviations (coronal, apical, angular), osteotomy extent, bone volume change, and 1-year periapical radiographic outcomes.

Main Results:

Data collection ongoing, with final outcomes assessed at 1-year post-surgery.
Efficiency will be determined by procedure time.
Accuracy will be evaluated using detailed measurements from CT scans and radiographs.

Conclusions:

The study aims to determine if DNS guidance improves the precision and efficiency of endodontic microsurgery.
Findings will inform the adoption of navigation technology in complex endodontic procedures.
This research contributes to advancing techniques for successful natural tooth preservation.
