Methods We selected cephalometric radiographs of 200 children with Angle’s Class Ⅱ division 1 malocclusion with ANB angle greater than 5°. A total of 22 measurements on hard and soft tissues were included. Results The average nasolabial angle of children with Angle’s Class Ⅱ division 1 malocclusion is 96.401°±11.265°. SN-Prn, SNCm-FH angle, UL’A’-FH angle, UL’SN-FH angle, and UL’-SN have a strong correlation with nasolabial angle. Conclusion The key factors affecting nasolabial angle are centralized in pates nasalis and upper lip soft tissue and are less relative with maxillary central incisor position and hard tissue morphology. The upper lip soft tissue is important in the cushioning within the facial soft tissue profile.<br>中图分类号 %K 鼻唇角 %K 安氏Ⅱ类1分类 %K 软组织 %K 鼻唇角 %K 安氏Ⅱ类1分类 %K 软组织 %K < %K /br> %K nasolabial angle %K Angle’s Class Ⅱ division 1 malocclusion %K soft tissue %K nasolabial angle %K Angle’s Class Ⅱ division 1 malocclusion %K soft tissue %U http://www.gjkqyxzz.cn/CN/10.7518/gjkq.2016.02.009
