Abstract

The aim of this study is to compare the skeletal and dentoalveolar changes produced by three protocols of maxillary protraction with skeletal anchorage: the bone-anchored maxillary protraction with titanium miniplates (BAMP), the miniscrew-anchored maxillary protraction with Class III elastics (MAMP) and with fixed nickel titanium coil springs (Modified-MAMP). Methods: The sample will comprise 61 individuals, of both sexes, ages ranging from 9 to 13 years, with Class III skeletal malocclusion. Group MAMP will consist of 18 individuals treated with Class III elastic anchored in a hybrid expander (with two palatal miniscrews) and 2 miniscrews in the distal of the mandibular permanent canines. Group Modified-MAMP will consist of 18 individuals treated with a fixed nickel-titanium coil spring anchored in a hybrid expander and in 2 mandibular miniscrews positioned distally to the permanent canines. Group BAMP will consist of 25 individuals treated with a Class III elastic anchored in two miniplates positioned in the infra-zygomatic crest and two miniplates in the mesial of the mandibular permanent canines. Cone-beam computed tomography (CBCT) will be obtained before (T1) and after (T2) treatment. Linear and angular three-dimensional changes will be compared after T1 and T2 CBCT cranial base superimposition using the open-source software ITK-SNAP and the 3D Slicer software. The analysis of variance will be used for intergroup comparisons. A significance level of 5% will be regarded for all tests. (AU)
