Factors impacting accuracy of dynamic computer-guided orthodontic miniscrew insertion

Investigators have explored the potential factors influencing the accuracy of miniscrew insertion during dynamic computer-guided orthodontic procedures, according to a study published in the Journal of Dentistry.

In the study, the investigators divided 24 patients into three groups on the basis of their palatal vault morphology: those with medium, steep/high or low/flat morphology. They then used a dynamic computer-guided system to insert two miniscrews into each patient and performed cone-beam computed tomography to determine the insertion accuracy.

The investigators found differences in angular deviation between the medium and high/steep as well as the low/flat and high/steep morphology groups. However, no differences were reported in the Apex-3D parameter or the length of the miniscrews. Accuracy of insertion was lower among the patients with high/steep palatal vaults.

The investigators underscored that individual palatal vault morphology should be considered when performing miniscrew insertion.
