摘　　要：目的:观察正畸治疗对牙周炎垂直型骨吸收患者牙周状况的影响。方法::随访观察37例伴垂直骨吸收牙周炎的错牙合患者,对比正畸治疗前、后及治疗后6个月,牙槽嵴高度、骨缺损量及牙槽骨骨密度,并进行统计学分析。结果:在治疗完成时和治疗后6个月随访时,垂直吸收位点检出率明显减低,牙周探诊深度(probing depth,PD)和临床附着丧失(clinical attachment loss,CAL)较治疗前均有明显降低(P<0.05),Ⅰ度松动牙数增多,而Ⅱ度松动牙数则减少。但在治疗完成时探诊出血指数(bleeding on probing,BOP)较治疗前升高。治疗后6个月随访时与治疗后比较,垂直吸收位点检出率和BOP、PD明显降低,Ⅱ度松动牙数明显减少(P<0.05)。釉牙骨质界至骨缺损间的距离(CEJ-BD)、骨缺损深度(bone destruction depth,BDD)在治疗完成时和治疗后6个月随访时,均较治疗前明显减小,而缺损区域的牙槽骨密度则有明显增加,差异具有统计学意义(P<0.05)。结论:采用低摩擦及轻力的正畸治疗,能迅速排齐牙列、消除咬合创伤,并促进垂直吸收的牙槽骨进行改建,重建咬合平衡,改善牙周健康状况。Objective： To observe the changes of periodontal conditions in patients with vertical alveolar resorption before and after orthodontic treatment. Methods： Thirty-seven adult patients with vertical alveolar bone resorption were received orthodontic treatment. The periodontal status of all the patients were evaluated by digital-panoramic radiograph,including alveolar ridge height,bone defect and bone mineral density during the first visit,before treatment,after treatment and 6months follow-up. Results： After treatment,the rate of vertical alveolar bone resorption,periodontal probing depth（ PD） and clinical attachment loss（ CAL） were reduced compared with those before treatment（ P〈0. 05）. But bleeding of probing（ BOP） after the treatment,was higher than that before treatment（ P〈0. 05）. The tooth mobility（ TM） ofⅠ° was also significantly increased,Ⅱ° TM was reduced. Compared to those just begore treatment,the rate of vertical alveolar bone resorption after 6 months of orthodontic treatment,PD and CAL were significant reduced（ P〈0. 01）,Ⅱ° TM was reduced than before.After treatment and after 6 months follow-up,CEJ-BD and BD which stand for vertical alveolar bone resorption were significant reduced（ P〈0. 05）. However,the density of alveolar defect was increased（ P〈0. 05）. Conclusion： Low-fiction and light force orthodontic therapy,which helped to align teeth quickly and eliminate occlusal trauma,can restore and maintain a stable occlusal that showed effectiveness in treatment of reconstruction and repair of periodontal tissues.
