| 摘 要： | 目的:分析比较用3 种不同的自锁托槽矫治系统治疗后,在治疗的早期上牙弓的宽度和牙弓周长的变化.方法:选择3 组轻度拥挤的病例,每组15 人,分别使用Damon自锁托槽矫治系统、Smart-clip自锁托槽矫治系统、Tomy自锁托槽矫治系统进行治疗.结果:前磨牙间和尖牙间牙弓的宽度和牙弓周长均显著增加.牙弓周长的增加与治疗前的牙弓周长显著相关.牙弓长度无显著改变.结论:自锁托槽矫治系统在治疗的早期可以显著增加上牙弓的宽度和牙弓周长,各自锁托槽矫治系统之间无显著性差异.

| Abstract: | Objective:To evaluate the changes in the transverse dimension and the perimeters of the maxillary archs produced by 3 self-ligating appliance systems during the leveling and aligning phases.Methods:45 patients who had class I skeletal pattern and upper arch crowding 3-6 mm were divided into 3 groups with 15 subjects in every group.The dental casts were analyzed.Results:Statistically significant increases were recorded of all dentoalveolar widths(with the exception of intermolar width measured lingually)and ... |
