ABSTRACT
Class II correction in non-growing patients will always pose a challenge in treatment, especially in a subdivision condition where one quadrant will exhibit class II molar and canine, and the other side will exhibit class I. In such a scenario, a contemporary extraction protocol will face a challenge in symmetric space closure. This case report describes the management of class II subdivision malocclusion by the latest approach, i.e., extraction of a single premolar. At the end of the treatment, midlines were corrected and good functional class I canine relations on both sides were established.
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.
