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类错牙合青少年患者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Gemini MBT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。

Abstract:

Objective    To evaluate the periodontal implication 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 respectively，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.
