【摘要】 目的观察自锁托槽对正畸患者牙周健康的影响。方法随机选择48例12～16岁错畸形患者,分为自锁托槽组和传统结扎式托槽组,前者使用3M公司Smartclip自锁托槽矫治器,后者使用GeminiMBT金属托槽矫治器。分别在戴矫治器后1、3、6个月检测下切牙牙龈指数(GI),菌斑指数(PLI),龈沟出血指数(SBI)。结果自锁托槽组牙周指数明显低于统结扎式托槽组。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。更多还原

【Abstract】 Objective To evaluate the periodontal implication of self-locking brackets.Methods Forty-eight cases of twelve to sixteen-year-old patients with malocclusion were randomly selected.The patients were divided into two groups,Group A(self-locking brackets,3M Smart clip Self-ligating Appliance System) and Group B(conventionally-ligated bracket,Gemini MBT).The type of brackets used was randomized for each group.A follow-up examination of mandibular incisor was carried out after one months,three months,six months,respectively.The periodontal condition was scored according to three parameters:GI,PLI,SBI.Results These of conventionally-ligated brackets group were significantly greater than these of self-locking brackets group.Conclusion To periodontal health,the effects of conventionally-ligated brackets were more serious than those of self-locking brackets.更多还原
