摘要: 目的 探讨无托槽隐形矫治中重启的影响因素,为正畸医生提供临床参考。方法 收集354例无托槽隐形矫治患者,将患者分为重启组和未重启组,并分析两组间12项影响因素,使用SPSS 19.0进行统计分析,采用单因素及多因素条件Logistic回归分析筛选出与隐形矫治重启相关的因素。结果 354例无托槽隐形矫治患者的重启率为39.27%,其中男性重启患者为31例,占比8.76%,女性重启患者为108 例,占比30.51%。多因素分析发现与未成年患者相比,成年患者的重启风险更小,约是未成年患者的40%(P=0.024),配合度差的患者重启风险增加了约5.7倍(P=0.000),需要弹性牵引配合的患者其重启风险增加了2.7倍左右(P=0.006),矫治步数大于48步的患者重启风险比矫治步数小于等于24步的患者增加了约3.6倍(P=0.027)。结论 患者的年龄(未成年患者)、配合程度差、需要弹性牵引、矫治步数(>48)是增加无托槽隐形矫治重启风险的影响因素,提示在临床上需要加强对这部分患者的监控和指导。

Abstract: Objective To investigate the influencing factors of restart in patients receiving clear aligner treatment and provide clinical reference for orthodontics. Methods A total of 354 patients receiving clear aligner treatment were collected and divided into restart group and non-restart group. Twelve factors were analyzed between two groups. SPSS 19.0 was used for statistical analysis, and univariate analysis and multivariate Logistic regression analysis were used to screen out factors related to restart. Results The restart rate of 354 patients with clear aligners was 39.27%, including 31 male patients (8.76%) and 108 female patients (30.51%). Further multivariate analysis showed that the restart risk of adult patients was lower than that of juvenile patients, about 40% of risks faced by juvenile patients (P=0.024). Patients with poor cooperation had a 5.7-fold increased risk of restart (P=0.000). The risk of restart increased about 2.7 times for patients requiring elastic traction cooperation (P=0.006). The restart rate of patient with over 48 treatment steps was 3.6 times higher than that of patients with less than 24 treatment steps (P=0.027). Conclusion Age of the patient (juvenile patient), need for elastic traction, poor cooperation and treatment steps (>48) are the influencing factors which would increase the risk of restart. It is suggested tha monitoring and guidance of these patients should be strengthened in clinic.
