| ［摘要］ 目的 分析固定正畸复发原因，为临床再治疗病例的诊断提供参考。方法 2003-09～2013-10该院完成矫治603例，复发56例（再治疗18例）。将完成矫治的603例患者分为未复发组和复发组，比较两组可能引起复发的临床资料是否存在统计学差异；对547例未复发和56例复发患者的保持、矫正、生长发育、智牙萌出、不良习惯破除情况进行统计，分析引起复发的主要因素，并对复发病例进行处理及处理后疗效评估。结果 未复发组和复发组比较，治疗年龄和治疗情况均具有统计学意义（P<0.01），而性别比较差异无统计学意义（P>0.05）。引起正畸复发的原因比较分析结果显示，保持情况、矫正情况和智牙萌出情况差异均有统计学意义（P<0.01或P<0.05）；生长发育和不良习惯破除差异无统计学意义（P>0.05）。56例复发者得到妥善处理并获得临床满意效果。结论 固定正畸复发与矫正计划密切相关，科学的矫正计划应包括充分保持，正确的诊断、合理的计划和良好的治疗时机以利于疗效的稳定，保持得当是减少复发的关键。 |

| ［Abstract］ Objective To analyze the main reasons of relapse after orthodontic treatment, and provide better understanding of the diagnosis for retreatment.Methods From September 2003 to October 2013, 603 patients received fixed orthodontic treatment in Laibin People′s Hospital,and of them relapse were found in 56 patients(18 patients went to retreatment).Six hundred and three patients were divided into relapse group （n=56）and non relapse group（n=547）, and the relevant clinical data were compared between two groups by univariate analysis.All clinical informations were collected in the two groups,including age, sex,retention period, growth pattern, the occlusion at the end of former treatment, wisdom teeth eruption, abnormal oral habit, and so on. The correlation analysis was performed between relapse and above factors. The efficacy of retreatment was assessed.Results Between two groups,there were significant difference in first diagnosed age and treatment(P<0.01), but no statistical significance in gender(P>0.05). Analyzing the factors of relapse showed,there were significant difference in the retention period,former treatment and wisdom teeth eruption(P<0.05), but no statistical significance in growth pattern and abnormal oral habit(P>0.05).Fifty-six patients with relapse were properly handled and obtained satisfactory clinical results.Conclusion Fixed orthodontic relapse is closely related to the correction plan, and scientific corrective plan should include sufficient retention,rational planning and good timing of treatment in order to facilitate stable curative effect,and proper retention is the key to reducing relapse. |
