Protraction facemask is one of the common effective methods to treat the patient with maxillary deficiency in mixed dentition and adolescent patients. In this case report, we present the treatment of a 10-year-old female patient with skeletal class III with maxillary retrognathism, anterior crossbite, left lateral incisor congenital missing, right peg lateral incisor and midline discrepancy with class III malocclusion. Treatment plan included protraction facemask with rapid maxillary expansion therapy, extraction of right peg lateral incisor and canine substitution. We also used temporary anchorage device (TAD) for molar asymmetry and midline correction while using facemask protraction to reach the bilateral Class II molar relationship. The final result was midline on and bilateral Class II molar relationship and facial profile was improved.
