Evaluation of the Accuracy of Palatal Orthodontic Miniscrew Placement.

Plain-language summary

This randomized clinical trial has the objective of comparing the accuracy of palatal paramedian miniscrew placement using static computer-assisted surgery (s-CAS) and dynamic computer-assisted surgery (d-CAS). A population of forty subjects requiring palatal paramedian miniscrew insertion is going to be randomized into two groups to receive two miniscrews placed with s-CAS (Group A; n=20 subjects, 40 miniscrews) and d-CAS (Group B; n=20 subjects, 40 miniscrews). Preoperative digital intraoral scans and CBCT images will be used for virtual planning. Group A procedures is going to employ patient-specific surgical guides, while group B procedures is going to be performed with real-time navigation. Immediate postoperative CBCT scans will be superimposed to measure four accuracy parameters: coronal, apical, depth, and angular deviation from the planned position. Statistical analysis will include Student's t-test or Mann-Whitney U test as appropriate.
