Meta-analysis of the effect of static computer-assisted dental implantation on the accuracy of dental implantation in esthetic area.

Background: This system evaluates the effect of static navigation systems on accuracy (platform, apical and angular deviation) in clinical studies of implant surgery in the anterior aesthetic zone to inform clinical decision-making.

Methodology: Retrieve Pubmed, Embase, Cochrane library databases, as well as randomized controlled trials (RCT) and controlled clinical trials (CCT) comparing dynamic navigation and static guidance published by the US Clinical Trial Registry before May 1, 2023. The outcome indicators included in the study include measuring the deviation between the preoperative design of the implant and the actual site at the top, apex, and angle. The calculation of meta-analysis was performed using Review Manager version 5.2 software.

Results: 1134 articles were screened and retrieved, and finally 4 studies were included for quantitative analysis. Meta analysis results showed that the two groups had lower depth angle deviation (WMD=-0.30, 95%CI: (0.24, 1.78), P=0.01) at the top (WMD=0.14, 95% CI: (-0.26, 0.55), P=0.49) and root tip (WMD=0.25, 95%CI: (-0.34, 0.84), P=0.41) compared to the static guide plate group, and the difference was statistically significant.

Conclusion: The static guide plate provides a small implant placement error, which is comparable to the error obtained using dynamic navigation systems, but dynamic navigation exhibits a smaller angle deviation.
