Objectives:
The study aimed to compare the accuracy of implant placement between static and dynamic computer-assisted systems (CAS) in a partially edentulous mandible model.
Materials & Methods:
A total of 80 implants was placed in mandible models. The implants were placed using either static or dynamic computer-assisted system. Deviations of implant hex, apex and angulation were measured between preoperative planning and postoperative CBCT in planning software.
Results:
The mean deviations of implant hex, apex and angulation in static CAS group were 1.15 ± 0.34 mm, 1.37 ± 0.38 mm and 2.60 ± 1.11 degree, while in dynamic CAS group were 0.40 ± 0.41 mm, 0.34 ± 0.33 mm and 0.97 ± 1.21 degree, respectively. Implant placement with dynamic CAS showed less deviations of shoulder, apex and angulation than with static CAS significantly.
Conclusions:
The implant accuracy using CAS system could be influenced by the guiding technique.
