The use of temporary anchorage devices for orthodontic treatment of high-angle Class III malocclusion in a patient with impacted upper canine teeth

This case report describes the orthodontic treatment of a 13-year-old female patient with high-angle Class III malocclusion, including anterior open bite and impacted upper canine teeth with a convex soft tissue profile. In this case, preadjusted edgewise appliances were placed after the extraction of the upper deciduous canine teeth, impacted upper canine teeth and lower first premolars. The upper and lower dental arches were aligned using a temporary anchorage device (TAD) for retraction and intrusion of the lower incisors avoiding the extrusion of the lower molars. A good facial profile and occlusion were achieved after active treatment.
