Summary
Static guidance (SG) and dynamic navigation (DN) improve accuracy in endodontic microsurgery compared to freehand methods. Further clinical trials are needed to confirm these findings and assess long-term outcomes.
Area of Science:
- Endodontics
- Surgical Technology
- Dental Research
Background:
- Persistent periapical pathology requires precise endodontic microsurgery.
- Digital advancements offer guided endodontic microsurgery options: static guidance (SG), dynamic navigation (DN), and augmented reality (AR).
- These technologies aim to enhance surgical accuracy and efficiency.
Purpose of the Study:
- To systematically review and compare the accuracy of SG, DN, and AR in endodontic microsurgery.
- To evaluate the impact of guided techniques on surgical precision.
Main Methods:
- Systematic review and meta-analysis following PRISMA guidelines.
- Searched PubMed, Scopus, and Google Scholar for studies comparing SG, DN, and AR in endodontic microsurgery.
- Assessed risk of bias and performed meta-analysis on comparable accuracy parameters from in vitro and cadaver studies.
Main Results:
- 33 studies included; meta-analysis focused on in vitro/cadaveric data due to limited clinical trials.
- SG and DN significantly reduced 3D global deviation at the bur tip compared to freehand (FH) (p < 0.01).
- DN showed greater resection angle deviation than SG (p < 0.01); AR data insufficient for meta-analysis; SG had least operating time.
Conclusions:
- Static guidance and dynamic navigation enhance accuracy and efficiency in endodontic microsurgery compared to freehand techniques in preclinical studies.
- Standardized outcome measures and further clinical trials are necessary for validation.
- Long-term clinical outcome data are needed.
