Investigation on the accuracy of implant surgery in dynamic navigation: metanalysis and systematic review of literature

Objectives: to compare through meta-analysis, the accuracy in implant placement obtained in Dynamic Navigation (DN) with Static Navigation (SN) and with freehand conventional surgery (CS) and to provide some useful clinical parameters to consider during the planning phase of the intervention. Material and methods: A mata-analysis was performed, dividing the selected studies into two groups based on the statistical technique adopted: DN vs CS, DN vs SN.. The heterogeneity between the various studies was assessed with the homonymous test and quantified with 12. The results were graphically represented using a forest plot. Egger’s test and funnel plot were used to investigate the “small study effect”. Results: The search performed through the Pub Med databased and the Cochrane Library database identified a total of 448 articles. After the application of the inclusion criteria, 14 articles were therefore selected, and then used for quantitative syntesis (meta-analysis) Conclusion: from the results obtained from this meta-analysis it can be stated that the DN mode allows for better accuracy than conventional surgery, the most used type of surgery, and comparable to Static Navigation, the gold standard for accuracy.
