Extraction of maxillary first bicuspids and mandibular lateral incisors, combined with orthognathic surgery to correct a severe class II skeletal malocclusion.Am J Orthod Dentofacial Orthop 2000; 117(3):312-9AJ
This is a case report of a 21-year-old female with a Class II Division 1 malocclusion. The maxillary arch was constricted with an associated anterior open bite. The lower facial height was excessive, and the mandibular plane angle was high. The treatment options were limited due to a previously extracted mandibular right lateral incisor. The patient was successfully treated by a surgical rapid palatal expansion procedure, extraction of the mandibular left lateral incisor, extraction of the maxillary first premolars at the time of a 3-piece Lefort 1 maxillary osteotomy procedure, and a bilateral sagittal split osteotomy advancement procedure.
