目的:探讨不同正畸术对牙周炎正畸患者的临床治疗效果。方法:选取本院口腔科2009年12月~2013年12月接收的97例行正畸治疗的牙周炎患者为研究对象,根据治疗方法的不同分为两组。A组(n=49)采用固定矫治器;B组(n=48)采用钢丝结扎联合复合树脂夹板。观察比较两组患者治疗后牙龈指数(GI)、牙周探诊深度(PD)、牙松动度(TM)及龈沟出血指数(SBI);比较两组患者治疗成功率及并发症发生率。结果:治疗后,A组患者GI、PD、TM及SBI均显著低于B组(P<0.05)。A组患者正畸成功率显著高于B组(91.8%VS 64.6%,χ2=10.6,P=0.001),并发症发生率显著低于B组(6.1%VS 20.8%,χ2=4.52,P=0.040)。结论:采用固定矫治器对牙周炎正畸患者进行治疗具有疗效确切、安全性高等特点,值得临床上推广应用。
Objective: To investigate the clinical effects of different orthodontics on orthodontic patients with periodontitis. Methods: A total of 97 patients with periodontitis receiving orthodontic treatment from December 2009 to December 2013 in our hospital were enrolled in this study. The patients were divided into two groups according to the different treatment methods. Group A (n = 49) used fixed appliance; Group B (n = 48) used steel ligation combined with composite resin splint. After treatment, the gingival index (GI), periodontal exploration depth (PD), tooth mobility (TM) and sulcus bleeding index (SBI) were observed and compared. The treatment success rate and complication rate were compared between the two groups. Results: After treatment, the GI, PD, TM and SBI in group A were significantly lower than those in group B (P <0.05). The success rate of orthodontic in group A was significantly higher than that in group B (91.8% VS 64.6%, χ2 = 10.6, P = 0.001). The incidence of complications was significantly lower in group A than in group B (6.1% VS 20.8%, χ2 = 4.52, 0.040). Conclusion: The fixed orthodontic appliance is effective in treating orthodontic patients with periodontitis. It is worth to be popularized and applied clinically.
