目的：探讨隐适美矫治器扩弓的效果及运动规律。设计的扩张量和身体扩张的效率之间的相关性进行了评估，作为初始磨牙扭矩和身体expansion.Materials和方法的效率：20名中国成年患者进行了弓扩张与Invisalign矫正器被纳入本研究。收集治疗前（T0阶段）和完成扩张阶段（T1阶段）后即刻的记录，包括数字模型和锥形束计算机断层扫描。采用海豚3D、Geomagic Studio 12.0和Meazure软件进行数据测量，计算预期与实际结果的差异。
Objectives: To investigate the efficiency and movement pattern of upper arch expansion using Invisalign aligners. The correlation between the amount of designed expansion and the efficiency of bodily expansion was evaluated, as were the initial molar torque and efficiency of bodily expansion.Materials and Methods: Twenty Chinese adult patients who underwent arch expansion with Invisalign aligners were included in this study. Records of pretreatment (T0 stage) and immediately after completing the expansion phase (T1 stage) were collected, including digital models and cone-beam computed tomography. Dolphin 3D, Geomagic Studio 12.0, and Meazure software were employed to measure data and calculate differences between the expected and actual outcomes.Results: There were significant differences between the expected and actual expansion amounts (P
