摘要： 目的：评价个性化唇侧固定矫治器在前牙轻度拥挤非拔牙矫治中的表达效率。方法：选择32例前牙轻度拥挤的安氏Ⅰ类或Ⅱ类错𬌗畸形患者,采用Insignia个性化唇侧矫治系统进行不拔牙矫治。收集矫治前、目标位以及矫治后的三维数字化牙列模型,测量上下颌牙弓宽度和转矩,并计算扩弓效率。结果：上下颌矫治后牙弓宽度较矫治前明显提高（P<0.05）,与目标牙弓宽度无统计学差异（P>0.05）。上颌牙位中,除第一前磨牙外,其余牙位实际扩弓量均显著小于目标扩弓量（P<0.05）;下颌牙位中,除第一磨牙外,其余牙位实际扩弓量与目标扩弓量无显著差异（P>0.05）。上颌扩弓效率第一前磨牙最高、第一磨牙最低,下颌则是第二前磨牙最高、第一磨牙最低。除下颌第一磨牙外,上下颌多数牙位矫治前转矩与目标转矩、矫治前转矩与矫治后转矩均有显著差异（P<0.05）;除上颌第二前磨牙外,其余牙位矫治后转矩与目标转矩无统计学差异（P>0.05）。结论：应用Insignia个性化唇侧矫治器治疗侧貌较好的前牙轻度拥挤病例,能高效扩宽牙弓,矫治效果接近目标位,但长期效果需进一步研究。

Abstract: PURPOSE: To evaluate the expression efficiency of personalized labial appliances in patients with mild dental crowding. METHODS: Thirty-two Class Ⅰor Class Ⅱ malocclusion patients with mild crowding of anterior teeth were selected. All patients were treated with the Insignia personalized labial correction system without tooth extraction. The three-dimensional digital dental models before treatment, at the target position and after treatment were collected. Then, the widths and torques of the maxillary and mandibular dental arches were measured, and the expansion efficiency was calculated. RESULTS: After orthodontic treatment, the widths of the maxillary and mandibular dental arches were significantly increased compared with those before treatment (P<0.05), but there was no significant difference compared with the widths of the target dental arches (P>0.05). Among the maxillary teeth positions, except for the first premolar, the actual expansion amounts of the other teeth positions were significantly less than the target expansion amounts (P<0.05); among the mandibular teeth positions, except for the first molar, there was no significant difference between the actual expansion amounts and the target expansion amounts of the other teeth positions (P>0.05). In the maxilla, the expansion efficiency was the highest for the first premolars and the lowest for the first molars; while in the mandible, it was the highest for the second premolars and the lowest for the first molars. Except for the mandibular first molars, there were statistically significant differences in the torques between pre-treatment and the target torques as well as between pre-treatment and post-treatment at most tooth positions in the maxilla and mandible (P<0.05). Except for the maxillary second premolars, there was no significant difference in the torques between pre-treatment and the target torques at the other tooth positions (P>0.05). CONCLUSIONS: The application of Insignia personalized labial aligners in the treatment of mild anterior tooth crowding cases with relatively good lateral profile can effectively widen the dental arch and achieve a correction result close to the target position. However, the long-term effect still needs further research.
