摘要
目的:研究安氏Ⅱ类错上下颌骨生长的特点,为安氏Ⅱ类错的临床治疗时机和治疗方法的选择提供参考。方法:收集安氏Ⅱ类错患者837例(男332例,女505例)。按CVM骨龄分期分组,测量头影侧位片,应用Win Ceph 6.0软件进行分析,SPSS 13.0进行方差分析后进行组间多重对比(CS1-CS6)。结果:男性组:下颌骨水平部、下颌升支、下颌骨总长度,在CS1-CS2和CS3-CS4期有明显增长;上腭长度、上颌总长度,在CS2-CS3期有明显增长。女性组:上颌骨总长度、下颌骨水平部、下颌骨总长度,在CS1-CS2和CS3-CS4期有明显增长。结论:男女下颌骨生长高峰出现在CS1-CS2和CS3-CS4时期;上颌生长高峰男性出现在CS1-CS2之间和CS2-CS3之间,女性出现在CS1-CS2之间和CS3-CS4之间。
Objective： To study the growth charactristics of mandible and maxilla in patients with Class II malocclusion.Methods： The records of 837 untreated subjects with Class II malocclusion（332 males and 505 females） were selected in the orthodontic clinic.The patients were divided into 6 groups according to their CVM.Win Ceph 6.0 was used for cephalometric analysis.The data were analyzed by SPSS 13.0.Results： In male group significant increase of Go-Gn,Cd-Go and Cd-Gn was observed in CS1-CS2 and CS2-CS3,significant increase of ANS-PNS and Cd-A was found in CS2-CS3.In Female group significant increase of Cd-A,Go-Gn and Cd-Gn was found in CS1-CS2 and CS3-CS4.Conclusion： The length of mandibular ramus and mandibular body may significantly growth in CS1-CS2 and CS3-CS4 in the male and female.The significant growth of maxilla is in CS1-CS2 and CS2-CS3 in the male and in CS1-CS2 and CS3-CS4 in the female.
