目的对比戴用自锁托槽与传统托槽矫治器后牙周指数的变化.材料和方法选取12～18岁正畸患者80例,按矫治器类型分为两组:实验组,40例采用AO公司生产的T3自锁托槽矫正的患者;对照组,采用杭州西湖公司生产的徐氏托槽矫正的患者40例.由同一牙周专科医师分别检测80例患者治疗前和治疗6个月的各项牙周指数(GI,PLI,SBI,PD).结果治疗6个月后两组间牙周指数(GI,PLI,SBI,PD)差异无显著性.结论自锁托槽矫治器不会更有利于牙周组织的健康,牙周的健康状况取决于患者的口腔卫生状况.

Objective To compare the periodontal indices between the use of self-ligating brackets and conventional pre-adjusted brackets. Methods Eighty patients (12 to 18 years old) were divided into 2 groups (group A: 40 patients with self-ligating brackets and group B: 40 patients with conventional pre-adjusted brackets). Periodontal indices (GI, PLI, SBI and PD) were examined in both groups. Results No difference was found in the indices recorded between the two groups after 6months of treatment. Conclusions Self-ligating brackets did not have an advantage over conventional brackets with respect to the periodontal status.
