Dentistry

Surgical Innovation

Background:

Targeted endodontic microsurgery (TEMS) utilizes a guided trephine bur approach for osteotomy and root-end resection, differing from traditional freehand methods.
Key differences include osteotomy size, resection control, surgical duration, and resection technique.
The clinical impact of these TEMS modifications on patient outcomes requires evaluation.

Purpose of the Study:

To assess the clinical outcomes of Targeted endodontic microsurgery (TEMS) at least one year post-treatment.
To compare the efficacy of TEMS with established freehand endodontic microsurgery techniques.

Main Methods:

A retrospective analysis of 23 patients (24 teeth) who underwent TEMS between June 2017 and May 2019.
Radiographic and clinical follow-up data at one year or beyond were assessed by two calibrated endodontists.
Outcomes were categorized into complete healing, reductive healing, or failure based on established criteria.

Main Results:

The study reported a 91.7% success rate, with 20 cases showing complete healing and 2 cases demonstrating reductive healing.
Radiographic assessment indicated complete healing in 20 cases, reductive healing in 3, and failure in 1 case.
No significant complications were noted in the results.

Conclusions:

Targeted endodontic microsurgery (TEMS) appears to achieve success rates comparable to conventional freehand techniques for root-end resection.
This study provides preliminary evidence supporting TEMS as a viable alternative.
Further controlled clinical trials with extended follow-up are recommended to confirm these findings.
