Abstract
The purpose of this study was to evaluate miniscrew
supported maxillary en masse retraction with and without
corticotomy-facilitated orthodontics. Twenty patients with maxillary or bimaxillary protrusion requiring orthodontic treatment with upper anterior en masse retraction in the extraction space of first premolars were selected. Patients were divided into two groups; control and corticotomy group each group consisted of 10 subjects. The retraction time was estimated .The cephalometric radiographs were analyzed for differences between pre-treatment and post-treatment variables that included skeletal and dental relationships. There was a significant difference in retraction time between control and corticotomy groups (p<0.001). Radiographic evaluation showed significant maxillary incisor retraction. Cortictomy assisted orthodontics reduces the duration of treatment compared to that without corticotomy.
