Role of Dynamic Navigation Systems in Enhancing the Accuracy of Implant Placement: A Systematic Review and Meta-Analysis of Clinical Studies

This systematic review and meta-analysis aims to investigate the influence of dynamic navigation systems on accuracy (platform, apical and angular deviations) in clinical studies.The research question was "Do dynamic navigation systems enhance the accuracy of implant placement?" The PubMed, Scopus and Embase databases were used to search the relevant studies up to January 2021. The role of dynamic navigation systems in enhancing the accuracy (platform, apical and angular deviations) of implant placement was then analyzed to conduct a systematic review and meta-analysis.Eight articles were analyzed in the systematic review and meta-analysis. The systematic review showed that the deviations in implant placement were significantly lower for dynamic navigation than for the freehand method, and there were no significant differences between the dynamic navigation and static guide methods. This meta-analysis showed that the dynamic navigation group exhibited less platform deviation, apical deviation and angular deviation than the control group. The results of subgroup analyses showed that the dynamic navigation group exhibited fewer deviations than the freehand group, and no significant differences were found between the dynamic navigation and static guide groups.Dynamic navigation resulted in higher accuracy than the freehand method, and similar accuracies were found between dynamic navigation and static guidance for platform deviation, apical deviation or angular deviations.
