摘要/Abstract

摘要：

目的:比较肌激动器和Fr&ankelⅡ(FRⅡ)型功能矫治器治疗安氏Ⅱ类1分类错的效果。方法:选择处于生长发育高峰期或高峰前期的患儿34例,其中12例用肌激动器矫治,22例用FRⅡ型矫治器矫治。所有患儿均为凸面型,上颌前突和(或)下颌后缩;ANB角\5b;磨牙及尖牙为远中关系。对比每个患儿矫治前后的模型和头侧位片并作统计学分析。结果:矫治结束后所有患儿磨牙和尖牙均达到或接近中性关系,ANB角减小至正常范围。使用 FRⅡ型矫治器组的患儿牙弓宽度比肌激动器组明显增加,而两组的基骨弓宽度无显著性差异。FRⅡ型矫治器使上切牙内收更显著,而肌激动器更能有效地控制下切牙的倾斜度。结论:两种功能矫治器都能有效地改善上下颌骨及牙弓的Ⅱ类关系。

Abstract:

Objective:The purpose of this study was to evaluate the effects of activator and FRⅡappliances on growing children with ClassⅡdivision 1 malocclusion.Methods:The material consisted of pre- and post-treatmentmodels and cephalograms of 16 boys and 18 girls. 12 childrenwere treatedwith activators, and 22 were treatedwith FRⅡappliances.Results:Both activator and FR Ⅱappliances can change ClassⅡrelationship to Class I, and significantly reduced ANB angle to a normal range. FRⅡappli- ance statistically increased the dental archwidth of the maxillary, and there was no statistically significant difference between these two groups in changing basal archwidth. The upperincisorswere retracted muchmore in the groups of FRⅡappliance, the axial inclination of the lower incisors was controlled more efficiently in the activator group.Conclusion:Both the activator and the FR Ⅱappliance can correct the ClassⅡmalocclusions efficiently. Selecting correct appliance is very important in the clinical treat- ment.
