| To investigate the effects of morphological characteristics of cranial base on malocclusion by analyzing characteristics of sagittal and vertical facial types of Angle's class II division 1 malocclusion so as to provide theoretical references for clinical diagnosis and correction of early Angle's class II division 1 malocclusion in permanent teeth. We randomly selected lateral radiographs of the skull of 80 patients at the age of 1214 years old from the Department of Orthodontics, Stomatological Hospital, Shanxi Medical University, China. There were 20 cases of Angle's class I malocclusion with average angle, 20 cases of Angle's class II division 1 malocclusion with average angle, 20 cases of Angle's class II division 1 malocclusion with low angle, and 20... |
