Maxillary Protraction through Posterior Miniplate Anchorage in a 10-Year-Old Class III Patient

Abstract

Background: In this study, treatment of maxillary deficiency through posterior maxillary miniplates connected to facemask was presented. Using skeletal anchorage rather than tooth-borne device, facilitated maxillary protraction with minimum dental changes. Also, the patient exhibited vertical growth pattern, which could be aggravated through tooth-borne devices. But through skeletal anchorage, clockwise rotation of mandible and counterclockwise rotation of maxilla were prevented. Desired results were obtained after 9 months of treatment including positive overjet, without any mandibular backward rotation and improved midface deficiency, followed by 10 months of retention period through using facemask only night time. Then, fixed orthodontic treatment was initiated to stabilize the results.
