摘要: 目的:探讨非减数治疗中,传统托槽与Damon自锁托槽系统在三维方向上对牙弓产生的影响差异,为临床提供参考。方法:选择非减数治疗的正畸患者45例,随机分为传统托槽+Cu-NiTi丝组(A组)、Damon 3mx+Cu-NiTi丝组(B组)和传统托槽+NiTi丝组(C组),各组按相同的弓丝顺序和时间排齐整平牙列。分别测量3组术前(T0)和排齐整平后(T1)牙弓前(a)、中(b)、后段(c)的宽度以及头颅侧位片中U1-SN、U1-PP、L1-MP、U6-PP(mm)、L6-MP(mm)等相关数据,采用SPSS22.0软件包对数据进行统计学分析。结果:通过方差分析和t检验,A、B、C 3组的相关数据在治疗前、后的改变量无显著差异。结论:在轻度拥挤的非减数病例中,Damon系统托槽与传统托槽对牙弓在三维方向上的影响无显著差异。

Abstract: PURPOSE: To compare the three-dimensional effect between traditional brackets and Damon self- ligating brackets on the arch during non-extraction treatment. METHODS: Forty-five patients with non-extraction treatment were included in this study. The patients were randomly divided into 3 groups. Patients in group A were treated with traditional brackets and Nickel titanium wire. Patients in group B were treated with Damon 3mx brackets and Cu-NiTi wire. Patients in group C were treated with traditional brackets and Cu-NiTi wire.Dentitions were aligned in each group according to the same order of arch wire and time. The widths of arch and cephalometric data, such as U1-SN, U1-PP, L1-MP, U6-PP (mm), L6-MP (mm) and other related datas, in T1 and T2 were measured and analyzed with SPSS 22.0 software package. RESULTS: Expansion and protrusion of the arch were observed, but there was no significant difference before and after treatment among 3 groups. CONCLUSIONS: There is no difference in the three-dimensional effect between Damon brackets and traditional brackets in non-extraction treatment of patients with mild crowding.
