摘　　要：目的 探讨牙周病致前牙间隙进行无托槽隐形矫治的临床效果.方法 选择2012年1月至2013年6月我院收治的牙周病致前牙间隙患者80例,按治疗方法分为治疗组和对照组,各40例.治疗组采用无托槽隐形矫治疗法,对照组采用常规固定矫治疗法.比较两组临床效果、探诊深度、菌斑指数、前牙间隙关闭时间等各项参数指标变化.结果 治疗后,两组患者前牙间隙、牙齿松动、1-NA距、1-NA角均有显著改善,但治疗组各项临床指标显著优于对照组（P＜0.05）;治疗后,两组患者探诊深度均显著提升,但治疗组探诊深度[（1.69±0.26） mm]提升幅度显著高于对照组[（1.56±0.18） mm]（P＜0.05）;治疗后,治疗组菌斑指数（9.8％）、前牙间隙关闭时间[（2.0±0.9）月]、矫治器松动（0）情况显著优于对照组（P＜0.05）.结论 牙周病致前牙间隙进行无托槽隐形矫治,短期观察未见牙周组织损伤,临床效果确切,适用于轻中度牙周病致前牙间隙的患者,值得临床推广.Objective To explore the clinical efficacy of invisible orthodontic correction without bracket for anterior tooth space caused by periodontal disease.Methods 80 patients with anterior tooth space caused by periodontal disease were selected from our hospital from January,2012 to June,2013 and then were divided into a treatment group and a control group according to different treatments,40 cases for each group.The treatment group were treated with invisible orthodontic correction without bracket,while the control group with routine fixed orthodontic correction.The clinical efficacies,probing depths,plaque indexes,times for closing front tooth gap,and the changes of other parameters in the two groups were compared.Results After the treatment,the anterior tooth gap,tooth looseness,1-NA distance,and 1-NA angle were significantly improved in both groups,but the clinical indicators of the treatment group were significantly better than that of the control group （P ＜ 0.05）; the probing depth was significantly improved in both groups,but the lifting amplitude of the probing depth were significantly higher in the treatment group （[1.69 ± 0.26] mm） than in the control group （[1.56-± 0.18] mm） （P ＜ 0.05） ; the plaque index （9.8％）,time for closing front tooth gap （[2.0 ± 0.9] months）,and appliance looseness （0） were significantly better in the treatment group than in the control group （P ＜ 0.05）.Conclusions Invisible orthodontic correction without bracket for anterior tooth space caused by periodontal disease doesn＇ t injury periodontal tissue in short term and is effective,suitable for the mild to moderate patients,and is worth being clinically generalized.
