摘　　要：目的:采用哈尔滨地区青少年正常[牙合]Bolton指数作为研究标准,探讨本地区各类错[牙合]患者Bolton指数及Bolton指数不调的发生率,为临床诊断和矫治设计提供参考。方法:选取2016年-2018年就诊于哈尔滨医科大学附属口腔医院正畸科的错[牙合]畸形患者的石膏模型240副,年龄13~17岁,按照安氏分类法分为四组,分别为安氏Ⅰ类,安氏Ⅱ类1分类,安氏Ⅱ类2分类,安氏Ⅲ类,每组60例(30男,30女),测量并分析Bolton指数。结果:哈尔滨地区不同错[牙合]患者Bolton指数前牙比、全牙比在性别上差异无统计学意义(P>0.05)。安氏Ⅰ类和安氏Ⅱ^2前牙比均小于安氏Ⅱ^1,安氏Ⅱ^2全牙比小于安氏Ⅲ类,差异具有统计学意义(P<0.05)。哈尔滨地区错[牙合]患者前牙比、全牙比不调发生率分别为33.75%、14.17%,不调发生率在不同错[牙合]类型间无统计学意义(P>0.05)。结论:不同安氏分类错[牙合]患者的Bolton指数存在差异,Bolton指数不调在本地区有较高的发生率,错[牙合]畸形患者诊断设计时应重视Bolton指数分析。Objective To explore the Bolton index and the incidence of disordered Bolton index of different kinds of malocclusion patients in Harbin according to the normal teenager Bolton index of Harbin,which provides reference resources for clinical diagnosis and orthodontic design.Methods Select 240 gypsum models of malocclusion patients aged between 13 and 17,who visited the orthodontics department of stomatological hospital in Harbin Medical University between 2016 and 2018.According to angle classification,the models were divided into class I malocclusion,ClassⅡdivisionⅠmalocclusion,ClassⅡdivisionⅡmalocclusion and ClassⅢmalocclusion respectively,each group included 60 patients case(30 males and 30 females).Measure and analysis the Bolton index.Results There is no statistics difference in anterior teeth ratio and overall teeth ratio in terms of gender according to the Bolton Index of malocclusion patients in Harbin.The anterior teeth ratio of classⅠmalocclusion and ClassⅡdivisionⅡmalocclusion are less than that of ClassⅡdivisionⅠmalocclusion,which has statistics significance(P<0.05).In addition,the overall teeth ratio of classⅡdivisionⅡmalocclusion is less than ClassⅢmalocclusion which has statistics significance(P<0.05).The incidence rate of disordered Bolton Index of malocclusion patients in Harbin in terms of anterior teeth ratio and overall teeth ratio are 33.75%and 14.17%respectively.There is no statistics differnence among different kinds of malocclusion(P>0.05).Conclusion There is a difference in the Bolton index of different type angle classification malocclusion patients and high incidence rate of disordered Bolton rate in Harbin area.Therefore,the analysis the Bolton index of malocclusion patients is quite significance in clinical diagnosis and orthodontic design.
