摘　　要：目的研究Damon3矫治器对正畸患者牙周组织健康的影响。方法选择2008—2010年在昆明医学院附属口腔医院正畸科治疗的安氏Ⅰ类错青少年患者30例,随机分为试验组和对照组,各15例。试验组患者戴用Damon3矫治器,对照组戴用GeminiMBT金属托槽矫治器。戴用矫治器后3、6个月检测牙龈指数(GI)、菌斑指数(PLI)及简化口腔卫生指数(OHI-S),并进行比较分析。结果固定矫治前,试验组与对照组间各牙周指标(GI、PLI、OHI-S)差异无统计学意义(P>0.05)。戴矫治器后,2组牙周指标均随时间的延长而升高,且试验组在戴矫治器后3、6个月GI、PLI、OHI-S均明显低于对照组,差异有统计学意义(P<0.05)。结论与传统结扎式托槽矫治器相比,自锁托槽矫治器更有利于牙周组织健康。Objective To evaluate the periodontal implicatiou of self-ligating brackets. Methods Thirty patients with malocclusion were randomly selected. The patients were divided into two groups： Group T1 （self-ligating brackets, Damon3） and Group T2 （3M Gemini MBT）. A follow-up examination of mandibular incisor was carried out after three months and six months, respectively. The periodontal condition was scored according to three parameters： GI, PLI, OHI-S. Results Before treatment, the GI, PLI and OHI-S had no statistical difference. After 3 and 6 months respec- tively, GI, PLI and OHI-S were obviously lower than those of the control group, the difference having statistical significance. Conclusion Compared with traditional brackets,the self-ligating brackets are better for peridontal health.
