错颌畸形患者正畸治疗的回顾性分析

目的分析错颌畸形患者的临床特征,为临床矫治提供参考.方法选取1997年1月至2016年6月正畸治疗的错颌畸形患者1387例,将其分为2组,I组(1997年1月至2006年12月)和Ⅱ组(2007年1月至2016年6月),比较两组患者的一般情况、错颌畸形的安氏分类、是否拔牙、矫治时间、保持器佩戴和复发情况等因素.结果女性患者占66.04%,男性占33.96%;患者年龄分布,以11~15岁区间患者为多,占66.33%;根据安氏分类统计,Ⅰ、Ⅱ、Ⅲ类错颌构成比分别为44.20%、40.88%、14.92%;Ⅰ组和Ⅱ组的全牙列矫治比例、复发率、保持器佩戴及拔牙情况差异均有统计学意义,且保持器佩戴情况与复发存在显著性相关.结论1997年1月至2016年6月女性正畸患者明显多于男性;Ⅱ组患者平均年龄有增大趋势、对拔牙矫治和保持器佩戴等正畸治疗的接受程度有明显提高,且保持器佩戴好坏与复发程度存在显著性相关.

Objective To explore the clinical features of malocclusion patients in the past 20 years and provide the clinical reference for treatment of malocclusion.Methods 1387 of malocclusion patients treated in our hospital from January 1997 to June 2016 were selected.They were divided into two groups,group I malocclusion patients treated from January 1997 to December 2006,group Ⅱ malocclusion patients treated from January 2007 to June 2016,the patients’characteristic,orthodontic dentition,Angle's classification,extraction,treatment duration,wearing retainer and recurrence were recorded and analyzed.Results Female malocclusion patients accounted for 66.04%,and male accounted for 33.96%.The age distribution of patients was 11~15,which accounted for 66.33%.The constituent ratios of Angle's classification Ⅰ,Angle's classification Ⅱ and Angle's classification Ⅲ were 44.20%,40.88%and 14.92% respectively,there were significant differences in the proportion of orthodontic dentition,the recurrence rate,wearing retainer and extraction in the two groups,and there was a significant correlation between wearing retainer and recurrence.Conclusion In the past 20 years,The number of female malocclusion patients is significantly higher than that of male,and the age of malocclusion patients has a tendency to increase,and the demand of orthodontic treatment is significantly increased,and wearing retainer is closely related to the recurrence.
