Comparison of the implant deviation between implants placed using static and dynamic computer assisted surgery methods

Abstract

Objectives: The aim of this study was to compare the accuracy of implant placement in terms of deviations related to the virtual plan between static and dynamic computer assisted implant surgery (CAIS) systems in single tooth space.

Materials & Methods: 60 single implants were randomly placed using two difference CAIS systems by one surgeon. Preoperative CBCT transferred to implant planning software were used to plan the virtual implant position. Implants were placed using either stereolithographic guide template for static CAIS group (n = 30) or implant navigation system for dynamic CAIS group (n = 30). Postoperative CBCT were taken to acquire the implant position and were imported to implant planning software in order to perform the implant deviation analysis. Primary outcomes were the deviations at implant platform, implant apex, and angular deviation.

Results: The mean deviations at implant platform and implant apex in static CAIS group were 0.97 ± 0.44 mm and 1.28 ± 0.46 mm respectively, while in dynamic CAIS group were 1.05 ± 0.44 mm and 1.29 ± 0.50 mm respectively. The angular deviation in static and dynamic CAIS group were 2.84 ± 1.71 degrees and 3.06 ± 1.37 degrees respectively. No significant differences between both groups was found.

Conclusions: Dynamic CAIS system provides the accuracy of implant placement in single tooth space similar to static CAIS system.
