RESUMO
This case report describes the protocol employed in the treatment of a patient with Class II malocclusion with mechanics including palatally positioned miniscrews. Treatment included the distalization of maxillary posterior teeth with mechanics including 2 miniscrews positioned on the palatal side. After a certain amount of distalization was achieved, the maxillary arch was bonded with Roth prescription brackets while the appliance was still active. When leveling of the upper arch was finished, the appliance was kept in the mouth as a retention device while the mandibular arch was bonded to continue treatment, which lasted for a total of 15.5 months. Mandibular and maxillary fixed retainers were placed at the end of active treatment. Pretreatment and post-treatment records revealed that vertical and sagittal skeletal cephalometric findings were not affected. Miniscrew anchorage used during distalization is an effective non-extraction treatment option for dental Class II malocclusion correction.
