牙周正畸联合治疗牙周炎致前牙移位的临床疗效分析

Effect and prognosis of orthodontic treatment on anterior teeth displacement by periodontitis

目的 研究牙周正畸联合治疗牙周炎致前牙移位的疗效及预后。方法 选取2010年1月~2014年12月来院接受治疗的牙周炎前牙移位患者40例（患牙数91颗）作为研究对象,所有患者均实施牙周正畸治疗,观察患者治疗前后牙槽骨吸收程度、牙龈出血指数、牙周袋深度等变化情况。结果 治疗后患者牙龈出血指数低级例数要明显多于治疗前（P〈0.05）;治疗后患者牙周袋深度要明显小于治疗前（P〈0.05）;治疗前牙齿松动程度以Ⅱ、Ⅲ度居多,治疗后Ⅰ度明显多于治疗前（P〈0.05）;治疗后患者牙槽骨吸收程度达到根颈1/3的比例要显著高于治疗前（P〈0.05）。本组患者治疗后显效者24（60.0%）例,有效者13（32.5%）例,无效者3（7.5%）例,治疗有效率为92.5%。结论 对牙周炎致前牙移位患者实施牙周正畸联合治疗,能够在改善患者牙周炎症的同时,矫正患者前牙的位置,具有较明显的疗效,可在临床推广应用。

Objective To study the effect and prognosis of orthodontic treatment on anterior teeth displacement by periodontitis. Methods 40 patients （91 teeth） with anterior teeth displacement by periodontitis were selected as study objects. The patients were treated with orthodontic treatment. The alveolar bone absorption degree, gingival bleeding index and periodontal pocket depth were observed. Results The number of patients with low gingival bleeding index before treatment was more than that after treatment（P〈0, 05）. The tooth mobility before treatment was higher than that after treatment（P〈0.05）. The alveolar bone absorption degree before treatment was higher than that after treatment （P〈0.05）. The effective rate was 92.5%. Conclusion Orthodontic treatment can improve periodontal inflammation and has the obvious curative effect.
