Comparative Analysis of Dynamic Versus Static Navigation in Implant Placement Accuracy.

Background: Precision in implant placement is a critical determinant of clinical success in implant dentistry. Computer-aided navigation systems, including static and dynamic modalities, have been developed to enhance accuracy. However, comparative data evaluating their effectiveness remain limited. Objective: This study aimed to compare the accuracy of implant placement using dynamic navigation versus static guided systems in terms of angular deviation, global entry deviation, and apical deviation. Materials and Methods: A total of 40 implants were placed in 20 partially edentulous patients. Each patient received two implants: one using static navigation and the other with dynamic navigation. Postoperative cone beam computed tomography scans were analyzed using specialized implant planning software to calculate deviations in implant position relative to preoperative planning. Mean deviations were compared using paired t-tests. Results: The mean angular deviation was significantly lower in the dynamic navigation group (2.15° ±0.68°) compared to the static group (3.74° ±1.12°; P < 0.001). Entry point deviation averaged 0.78 ± 0.25 mm for dynamic navigation and 1.14 ± 0.38 mm for static guidance (P = 0.003). Apical deviation was 1.12 ± 0.31 mm for dynamic navigation versus 1.55 ± 0.49 mm for static navigation (P = 0.001). Conclusion: Dynamic navigation demonstrated superior accuracy compared to static guidance in implant placement. These findings suggest that dynamic systems may offer clinicians enhanced control and precision, especially in anatomically complex cases.
