Accuracy of Computer-Aided Dynamic Navigation Compared to Computer-Aided Static Navigation for Dental Implant Placement: An In Vitro Study

摘要

Aim: To analyze the accuracy capability of two computer-aided navigation procedures for dental implant placement. Materials and Methods: A total of 40 dental implants were selected, which were randomly distributed into two study groups, namely, group A, consisting of those implants that were placed using a computer-aided static navigation system ( = 20) (guided implant (GI)) and group B, consisting of those implants that were placed using a computer-aided dynamic navigation system ( = 20) (navigation implant (NI)). The placement of the implants from group A was performed using surgical templates that were designed using 3D implant-planning software based on preoperative cone-beam computed tomography (CBCT) and a 3D extraoral surface scan, and the placement of group B implants was planned and performed using the dynamic navigation system. After placing the dental implants, a second CBCT was performed and the degree of accuracy of the planning and placement of the implants was analyzed using therapeutic planning software and Student’s -test. Results: The paired -test revealed no statistically significant differences between GI and NI at the coronal ( = 0.6535) and apical ( = 0.9081) levels; however, statistically significant differences were observed between the angular deviations of GI and NI ( = 0.0272). Conclusion: Both computer-aided static and dynamic navigation procedures allow accurate implant placement.
