摘要： 目的: 评价Damon自锁矫治系统与Roth传统矫治器非拔牙治疗上颌轻中度拥挤的临床效果。方法: 选取骨性Ⅰ类正畸患者60例,根据矫正器种类及上颌拥挤程度分为DamonⅠ、RothⅠ、DamonⅡ、RothⅡ4组（各15例）。测量排齐整平前、后的头颅侧位片与模型,使用SPSS19.0软件包对所得数据进行配对t检验和独立样本t检验,分析治疗前、后以及各组间软、硬组织与牙弓形态的变化特征。结果: 非拔牙治疗上颌Ⅰ度拥挤时,2种托槽治疗前、后各段牙弓宽度与牙弓长度、上前牙唇倾度均有增加,但无显著差异。非拔牙治疗上颌Ⅱ度拥挤时,DamonⅡ组在上颌尖牙区（1.81 mm）、前磨牙区牙弓宽度的扩大量（2.29 mm)显著大于RothⅡ组（1.66 mm,1.80 mm）（P<0.05）,但DamonⅡ组牙弓长度扩大量（3.19 mm）、上前牙唇倾度的变化量（9.1°）显著小于RothⅡ组（3.85 mm,14.5°）（P<0.05）,而上颌磨牙牙弓宽度的扩大量在2组之间无显著差异。结论: 在非拔牙治疗牙列拥挤时,随着上颌拥挤度的增大,Damon自锁矫治系统的扩弓作用和控制前牙唇倾的优势越明显。

Abstract: PURPOSE: To compare the clinical efficacy of non-extraction treatment in maxillary mild-to-moderate crowding cases with Damon self-ligating system and Roth traditional brackets. METHODS: Sixty skeletalⅠorthodontic patients were selected in this study. They were divided into DamonⅠ, RothⅠ, DamonⅡ and RothⅡ group according to the bracket species and maxillary crowding degrees. Lateral cephalometric radiographs and models were measured before and after aligning and leveling to analyze the changes in dental arch and soft and hard tissue using SPSS 19.0 software package. RESULTS: After non-extraction treatment of cases with mild (Ⅰ) crowding, significant increase was found in dental width ,dental length and upper incisor torque produced by two brackets. However, there was no significant difference between the two groups. After non-extraction treatment of cases with moderate(Ⅱ) crowding, the width of maxillary canines (1.81 mm) and premolars (2.29 mm) of Damon Ⅱ group were significantly greater than those of Roth Ⅱ group (1.66 mm, 1.80 mm) (P<0.05). The changes of arch length (3.19 mm)and upper incisor torque (9.1°) in Damon Ⅱ group were significantly less than those in Roth Ⅱ group (3.85 mm, 14.5°). There was no significant difference of increased widths between maxillary molars in the two groups. CONCLUSIONS: With the increase of maxillary crowding level, the advantages of expansion and controlling the torque of anterior teeth are more obvious in non-extraction treatment using Damon self-ligating system.
