Abstract | 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. (C) 2020 Elsevier Masson SAS. All rights reserved. |
