摘要
目的:分析固定矫治后导致患者的复发相关因素,为预防正畸复发提供依据。方法:对2010年固定矫治后结束的患者152名进行回访,根据复发的标准分为复发组和未复发组,对两组患者的性别、年龄、患者的依从性、保持器类型、拔牙数、错牙合畸形类型差异等六个因素进行单因素差异显著性分析。再将分析结果有意义的因素进行多因素Logistic分析,分析复发的高危因素。结果:单因素分析结果显示保持器类型与复发关系的OR值为3.586,表明使用Hawley保持器与压膜保持器相比更容易产生复发,是复发的危险因素。患者的依从性与复发关系的OR值为0.86,是复发的保护因素。经多因素Logistic回归分析,在保持器类型、患者依从性两项指标中,只有患者依从性与复发密切相关,OR值为0.86,是复发的保护因素。表明患者依从性越好越不易发生复发。结论:复发与否与按时复查,是否良好戴用保持器密切相关,与拔牙数,年龄,性别,错牙合畸形类型,保持器类型相关性不大。
Purpose Analysis after the fixed appliance to maintain the relevant factors of recurrence in patients, compared to hawley retainer, and the clinical effect of squeeze film retainer. Methods and methods full mouth fixed appliance to maintain at least two years after the 152 patients Will all return visits to the patients, divided according to the standard recurrence recurrence group and non-recurrent group, compared the two groups were age, sex, time and referral rate, retainer type, extraction number of different types of malocclusion deformity, and the difference significant analysis. Risk factors for recurrence of multivariate logistic analysis, analysis of risk factors for recurrence. Results Recurrence group and the group without recurrence wear situation, there remain differences in type. Regression analysis showed that wear conditions(OR = 0.86) for the recurrence of protective factors. Conclusions Relapse or with the time and review, a good retainer wear is closely related with the extraction, age, gender, type of malocclusion deformity, maintaining type is not relevant.
