Accuracy of Computer Aided Dynamic Navigation Compared to Computer Aided Static Navigation for Dental Implant Placement: An In Vitro Study
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 (n 20) (guided implant (GI) and group B, consisting of those implants that were placed using a computer aided dynamic navigation system (n 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 t test. Results: The paired t test revealed no statistically significant differences between GI and NI at the coronal (p 0.6535) and apical (p 0.9081) levels; however, statistically significant differences were observed between the angular deviations of GI and NI (p 0.0272) Conclusion: Both computer aided static and dynamic navigation procedures allow accurate implant placement.
