摘　　要：目的:与压膜保持器做比较,探讨正畸舌侧固定保持器1年后的保持效果,以期为临床应用提供理论依据。方法:回顾性的选择固定正畸治疗结束的患者65例(男31例,女34例),年龄(14.57±0.35)岁,其中33例接受了下颌舌侧麻花丝保持器,32例使用压膜保持器。分别测量65例患者固定正畸结束时和1年后的模型,测量项目主要包括下颌尖牙间宽度、磨牙间宽度、牙弓长度以及Little前牙不齐指数。采用SPSS17.0软件包对数据进行Wilcoxon秩和检验分析。结果:65例患者戴用正畸舌侧固定保持器和压膜保持器一年后起到了良好的保持效果,且两者差别无统计学差异。结论:正畸舌侧固定保持器能有效防止下颌牙齿的复发,临床上正畸医生应根据患者的具体情况选择合适的保持器类型。Objective Compared with the vacuum-formed retainer, to explore the effect of lingual fixed retainer after a year, in order to provide theoretical basis for clinical application.
