The frequency and distribution of skeletal and dental components in Class II orthognathic surgery patients

In an effort to identify the skeletal and dental relationships of Class II malocclusion, lateral cephalograms of 253 adult orthognathic surgery patients (76 male, 177 female) who had a Class II molar and cuspid relationship were traced. One hundred and four of the subjects had had presurgical orthodontic treatment and 148 had not. The most common combination of variables found in this study population was a retrusive maxilla, protrusive maxillary incisors, protrusive mandibular incisors, a retrusive mandible, and a long lower facial height.
