The first step in the development of digital implantology was the use of static, template-based implantation. This was followed by dynamic navigation, which allows real-time control of the surgery. The aim of this study was to assess the accuracy of surgery performed with a dynamic navigation implantation system and to compare its calibration methods in terms of accuracy. 44 implants were placed in 14 patients by 1 surgeon. Planning software was used to determine the position of the implants based on pre-operative CBCT, and implant placement was performed under real-time control of dynamic navigation. A postoperative CBCT scan was performed. Measurements were taken made after surgery, and the difference of planned implant position on virtual images and control CBCT images were superimposed. The parameters tested were angular deviation, platform deviation, and apical deviation. Calibration was performed with tracer technic in 3 cases and with clip technic in 11 cases. The dynamic navigation system makes high precision implant placement possible. The tracer calibration method does not require a marked CBCT scan, and it has a similar accuracy as one based on clip calibration. The accuracy of implant placement by dynamic navigation can be improved by trenching.
