[摘要]目的：综合评价热压膜透明联冠保持器的临床应用特点及疗效。方法：将通过固定矫治技术完成矫治后的各类错牙合 80例随机分为实验组、对照组，每组40例。实验组用热压膜透明联冠保持器，对照组用改良式Hawley's保持器，观察时间6个月。观察指标：①对保持器的主观认同感；②保持疗效；③因保持器本身问题的复诊率；④技工室、临床操作时间、操作工序比较。结果：①主观认同感方面无论是对美观、发音的影响，还是戴用舒适度、保持器固位情况、及取戴难易程度方面，二者均存在显著性差异； ②临床、技工室制作所需时间，二者也存在显著性差异；③因保持器本身问题的复诊率及保持疗效方面，二者虽有差异，但差异无显著性。结论： 热压膜透明联冠保持器较改良式Hawley's保持器无论在患者认同感，还是临床、技工室操作方面均表现出明显优越性，且保持疗效确切，适宜临床普及推广。

Abstract: Objective To evaluate the characteristics and clinic effects of transparent full-arch wraparound retainer. Methods 80 patients who required retention after orthodontic treatment were divided into 2 groups randomly and each group had 40 patients.One group worn transparent full-arch wraparound retainer,the other worn reformed Hawley retainer.The period of observation was 6 months and the study indexes were used as follows:①the patient compliance.②the retention effects of treatment results.③the rates of further consultations because of the drawbacks of retainers.④the laboratory time,the chairtime,the laboratory and clinic procedures. Results ①There was significant difference in the patient compliances such as esthetics, effects in speech, comforts, fixations and convenient in retainers wearing or taking off between two retainers.②There was significant difference in the laboratory time and the chairtime too. ③There was difference but not significant difference in the rates of further consultations because of the drawbacks of retainers and the orthodontic treatment results retaining.Conclusion Transparent full-arch wraparound retainer has obvious advantages over Hawley retainer not only in patient compliances but also in laboratory and clinic procedures, and it's retention effects were positive. So it can be used widely in orthodontic retentions.
