An already established alternative to conventional orthopedic treatment with palatal expansion and face mask for growing patients with skeletal Class III due to maxillary deficiency is the use of skeletal anchorage for protraction of the maxilla. Its use eliminates the adverse dental effects of conventional therapy, such as extrusion and mesialization of upper molars, projection of upper incisors and retroinclination of lower incisors. In addition, it eliminates the need to use an extra-oral device, which contributes to patients' motivation. Mini-plates are the most commonly used skeletal anchorage for this type of therapy, however the need for a surgical step for installation and another for removing plaques represents a disadvantage for this technique, and thus the use of miniscrews was proposed to perform maxillary protraction eliminating the surgical step. This work aims to describe the technique of maxillary prostration supported by orthodontic miniscrews, illustrated through a clinical case of a patient treated with this therapy, showing the positive facial and occlusal results achieved.
