The aims of the present study are to measure and compare dental implant deviations with fully guided and pilot drill–guided protocols using dynamic navigation systems in polyurethane models. The pilot drill–guided group was determined to be the study group and included 12 implant applications. In this group, the pilot hole was drilled with navigation guidance, and the procedure was completed freehandedly. In the control group, all drilling and implant placement steps were performed using the navigation system, and a total of 12 implants were placed. The pre- and postoperative images were compared to calculate the magnitude of implant deviation. The quantitative data of the 2 groups were compared using the independent-samples t test and Mann-Whitney U test. The analyses revealed that the length of the procedure differed significantly between the 2 groups (P < .001). The procedure duration was significantly shorter in the study group. The entry deviation values of the 2 groups were not significantly different (P = .079). The analysis revealed the apex deviation to be higher in the study group than in the control group (P = .003). However, the 2-dimensional vertical apex deviation values of the implants were not significantly different between groups (P = .068). Angular deviation was determined to be significantly higher in the study group (P < .001). In the present study, all implants were successfully placed in the models using a dynamic navigation system. The results of this study may be useful for future clinical studies.
