The purpose of this study was to investigate the morphological characteristics of the cranio-dento-facial complex of children with deciduous dentition and Class III malocclusion. Forty Chinese children in Taiwan with normal occlusion and 40 with Class III malocclusion in deciduous dentition were selected for cephalometric analysis. Mandibular length was significantly greater and the mandible was situated farther forward in the Class III group. The maxilla was also slightly backward in this group, perhaps in association with the shorter maxillary length. The mandibular incisors were tipped lingually to compensate for the intermaxillary skeletal dysplasia and the maxillary incisors were tipped lingually by the retroinclined mandibular incisors.
本研究的目的是调查乳牙期安氏III类错牙合儿童颅-牙-面复合体的形态特征。选取40名台湾地区乳牙期咬合正常的中国儿童和40名乳牙期安氏III类错牙合儿童进行头影测量分析。安氏III类组的下颌长度明显更长，下颌位置更靠前。该组上颌也略向后，可能与上颌长度较短有关。下颌切牙舌倾以补偿颌间骨骼发育异常，而上颌切牙因下颌切牙向后倾斜而舌倾。
