摘　　要：目的探讨正畸治疗后复发的危险因素,为预防正畸治疗后复发提供依据。方法回访2006年结束正畸治疗的患者128例,对性别、患者依从性、牙根位置颊舌向、矫治结束时年龄、牙槽骨高度和牙周膜炎症、矫治结束后医生对患者的管理、保持器类型、矫治结束时的咬合关系、矫治结束时的牙根情况,以及矫治时间10个因素进行单因素分析,再把分析结果有意义的因素进行多因素非条件logistic回归分析。结果回归分析显示3个因素相关:矫治结束后医生对患者的管理(OR=7.77)、矫治结束时的咬合关系(OR=4.54)、患者依从性(OR=3.53)。结论矫治结束后医生对患者合理管理、矫治结束时咬合关系稳定、患者依从性好有利于降低正畸治疗后复发的风险。Objective To explore risk factors of the relapse of post orthodontic treatment so as to help prevent relapse. Methods A total of 128 patients,who finished orthodontic treatment in 2006,were retrospectively examined. A single factor analysis was used for 10 possible risk factors including gender,patient compliance,cheek or tongue position of root,age of finishing treatment,alveolar bone height and periodontal membrane inflammation,patient management after the treatment,retainer type,occlusion,parallel of root,and treatment time. Based on single factor analysis,the multi-factor unconditioned logistic regression analysis was made. Results The results of logistic regression analysis revealed 3 statistically significant risk factors： the management for patient after the treatment（ OR =7. 77）,the occlusion at the end of treatment（ OR = 4. 54）,and the compliance of patient（ OR = 3. 53）. Conclusions Reasonable management after the treatment,stable occlusion,and good compliance contributed to reducing the risks of the orthodontic posttreatment relapse.
