Dynamic navigation system accuracy in orthodontic miniscrew insertion in the palatal vault: a prospective single-arm clinical study.

This article focuses on evaluating the accuracy of dynamic navigation (DN) systems in the insertion of orthodontic miniscrews in the palatal vault. In a prospective clinical study involving 23 subjects and 46 miniscrews, deviations between planned and actual miniscrew positions were measured using pre- and postoperative imaging, assessing entry point, apex point (3D and vertical), and angular deviations. Results showed mean deviations of 2.55 mm at the entry point, 3.11 mm at the apex point, 0.87 mm vertically at the apex, and an angular deviation of 8.50 degrees, with no significant correlation between accuracy and the number of surgeries performed; however, the duration of interventions decreased significantly with experience. The study concludes that DN is a viable alternative to static computer-assisted surgery for miniscrew placement in the palatal vault, despite a relatively wide range of deviations, and highlights the benefit of reduced procedure time as operator experience increases.
