Early treatment of Class III malocclusion by RME and modified Tandem appliance

摘要

Patients with a skeletal Class III malocclusion and maxillary deficiency can be treated successfully using a combined protraction facemask and alternate rapid maxillary expansions and contractions (Alt-RAMEC). However, due to poor patient compliance during facemask therapy there has been growing interest in intraoral appliances for correcting Class III malocclusion. The tandem traction bow appliance (TTBA) is an intraoral appliance which has been used successfully for the treatment of growing Class III patients. This case report describes the management of a 10-year-old boy with a Class III malocclusion and maxillary deficiency treated with modified TTBA appliance.
