Orthodontic correction of a class III malocclusion in an adolescent patient with a bonded RPE and protraction face mask.

A case report of a 14-year-old Hispanic male with a Class-III skeletal profile and dental malocclusion with a long mandibular body and ramus and retrusive maxilla. The patient was initially referred for a surgical evaluation for a LeFort I maxillary advancement, but he wanted to avoid surgery. The Class-III malocclusion was corrected with a bonded rapid palatal expander and a maxillary protraction mask followed by nonextraction orthodontic treatment. A Class-I molar and canine relationship was achieved, and the facial profile improved. This case report demonstrates the orthodontic correction of a Class-III malocclusion in an adolescent patient with a bonded rapid palatal expander and protraction face mask. This case was presented to American Board of Orthodontics as partial fulfillment of the requirements for the certification process conducted by the Board.
