ABSTRACT
The correction of skeletal class III malocclusions is one of the most difficult orthodontic treatments. Skeletal Class III malocclusion may result from a combination of maxillary deficits and mandibular prognathism, mandibular prognathism alone, or maxillary deficits alone. Treatment options include an orthopedic appliance (facemask and chin cup), orthodontics with camouflage, a combination of orthognathic surgery and orthodontics, and the recently introduced bone-anchored maxillary protraction. This case report describes the treatment of a young, growing patient with a retrognathic maxilla using Hyrax with an acrylic splint using the alternative rapid maxillary expansion and constriction protocol and a Petite type facemask.
