目的：评价自锁矫治器在成人牙周炎患者进行牙周-正畸联合治疗过程中临床应用的效果。方法选取24例前牙呈扇形展开具有散在间隙、需要正畸治疗的成人牙周炎患者,分别应用Bioquick自锁托槽矫治器和MBT托槽矫治器进行矫治,记录牙周治疗前( T0)、牙周治疗后( T1)和正畸矫治后( T2)的牙周指标PLI、PD、SBI、BOP、CAL。应用SPSS13．0统计软件分析各项检测指标。结果与T0阶段相比,Bioquick组和MBT组的T1、T2阶段PLI、SBI、PD、BOP组内比较均有显著性差异( P<0．05), T1与T2阶段组内比较无显著性差异( P>0．05)。Bioquick组和MBT组两组间各测量指标T2相对T0术前术后改变差值比较均无统计学意义( P>0．05)。结论牙周病患者进行牙周正畸联合治疗有利于牙周组织的改建和愈合；正畸矫治有助于维护牙周炎的长期疗效；自锁托槽相对于传统托槽对牙周组织状况的改善没有显著优势。%Objective To evaluate the clinical effect of self-ligating brackets during periodontal-orthodontic treatment in adult periodontitis patients. Methods Twenty-four adult periodontitis patients with scattering gap of the anterior teeth,who needed orthodontic treatment, were included in the study . The patients were divided into two groups of 12 and treated with Bioquick self-ligating brackets and conventional MBT brackets, respectively. The PLI, PD, BI, OP and AL were recorded before periodontal treatment (T0),after periodontal treatment (T1), and at the end of orthodontic treatment (T2). The data were statistically analyzed. Results Significant difference in PLI, SBI, PD, BOP in each group was found between T0 stage and T1 stage,between T0 stage and T2 stage (P<0. 05). All periodontal indexes of each group were not significantly different between T1 stage and T2 stage ( P >0. 05 ) . The improvement from T2 to T1 was not significant between Bioquick group and MBT group ( P>0. 05 ) . Conclusion Orthodontic and periodontal treatment of periodontitis patients was beneficial to periodontal tissue. Orthodontic treatment can maintain the long-term curative effect of periodontal treatment. The self-ligating brackets did not better improve the periodontal tissue condition than the conventional brackets.
