    Objective:To evaluate the accuracy of implant placement guided by dynamic navigation by comparing digital intraoral scanning (IOS) with the traditional cone beam CT (CBCT)-based method, and to provide further evidence for the feasibility of using IOS as an evaluation tool.Methods:Sixty mandibular resin models were printed, and 2 implants (31 and 36) were placed in each model using dynamic computer-aided implant surgery. One hundred and twenty implants were placed. Postoperatively, the achieved implant positions were assessed using both CBCT and IOS. The implant deviations were then measured by importing the data into an accuracy analysis software.Results:Significant differences between CBCT and IOS were observed in global coronal and angular deviations (P<0.01), but not for the other deviations. The differences between the two methods were statistically significant for the global coronal, lateral coronal, and angular deviations (P<0.01) at site 31, and for the vertical coronal, vertical apical, and angular deviations (P<0.05) at site 36.Conclusion:The accuracy of the IOS-based evaluation method for measuring implant accuracy is consistent with that of the conventional CBCT assessment method and meets the clinical requirements. However, further clinical study is required to confirm the accuracy and feasibility of this method.
