Herbst功能矫治器在骨性Ⅱ类错中的效果研究

Study on the effect of Herbst appliance in the treatment of patients with skeletal classⅡ malocclusion

目的研究及观察Herbst功能矫治器在骨性Ⅱ类错中的效果。方法选取2011年6月至2012年7月于该院进行诊治的48例骨性Ⅱ类错患者为研究对象,将其随机分为对照组(Activator功能矫治器组)24例和观察组(Herbst功能矫治器组)24例,然后将两组治疗前后的头影测量指标及牙周健康相关指数进行比较。结果观察组治疗后的头影测量指标均明显优于对照组及治疗前,治疗后不同时间的菌斑指数、牙龈指数及出血指数等牙周健康相关指标也均好于对照组,差异有统计学意义(P<0.05)。结论 Herbst功能矫治器在骨性Ⅱ类错中的效果更好,不仅仅临床疗效较佳,且对牙周健康的不良影响也较小。

Objective To study and observe the effect of Herbst appliance in the treatment of patients with skeletal Ⅱ II malocclusion .Methods 48 patients with skeletal class Ⅱ malocclusion in our hospital from June 2011 to July 2012 were selected as research object ,and they were randomly divided into control group（Activator appliance group）24 cases and observation group（Herbst appliance group）24 cases ,then the cephalometric indexes and periodontal health related indexes of two groups before and after the treatment were compared .Results The cephalometric indexes of observation group after the treatment were all better than those of control group and those before the treatment ,the periodontal health related indexes including plaque index ,gingival index and bleeding index at different times after the treatment were all better than those of control group too （all P〈 0 .05） ,there were all significant differences .Conclusion The effect of Herbst appliance in the treatment of patients with skeletal class Ⅱ malocclu-sion is better ,and the clinical effect is better ,at the same time the bad influence for periodontal health is smaller .
