Distalization is a fundamental orthodontic strategy for correcting Class II and Class III malocclusions, particularly in cases where specific dental or skeletal conditions favor its application. Recent technological advances have enabled complex dental movements to be performed using clear aligners, aided by digital planning platforms such as ClinCheck. This retrospective study aimed to evaluate the accuracy of ClinCheck in predicting molar and canine distalization outcomes with the Invisalign system and to identify clinical factors influencing treatment predictability. Thirty patients with complete permanent dentition and at least 2 mm of programmed distalization were selected. Planned movements were extracted from the Invisalign Doctor Site and compared to achieved outcomes using Geomagic Control X™ software. Occlusal improvements were assessed using the . The results revealed significant discrepancies between the programmed and achieved distalization, with mean deviations greater than 1 mm in both arches. Skeletal anchorage with significantly improved distalization outcomes in the maxillary arch; however, no significant effect was observed in the mandibular arch. Additionally, no significant associations were found between distalization outcomes and skeletal pattern () or . Clear aligners are effective in achieving substantial occlusal improvements, particularly when combined with personalized digital planning and supplementary strategies such as skeletal anchorage. Mandibular cases demonstrated greater reductions in PAR scores, emphasizing the potential of aligners in complex distalization treatments.
远中移动是矫治安氏II类和III类错牙合畸形的一项基本正畸策略，尤其是在特定的牙齿或骨骼状况有利于其应用的情况下。最近的技术进步使得借助ClinCheck等数字规划平台，使用透明矫治器就能实现复杂的牙齿移动。这项回顾性研究旨在评估ClinCheck在预测Invisalign系统中磨牙和尖牙远中移动结果方面的准确性，并确定影响治疗可预测性的临床因素。选取了30例恒牙列完整且计划远中移动至少2毫米的患者。从Invisalign医生网站提取计划移动，并使用Geomagic Control X™软件将其与实际结果进行比较。使用[具体评估指标]评估咬合改善情况。结果显示，计划的远中移动与实际实现的远中移动之间存在显著差异，两个牙弓的平均偏差均大于1毫米。在上颌弓中，[具体骨骼锚固方式]显著改善了远中移动结果；然而，在下颌弓中未观察到显著效果。此外，远中移动结果与骨骼类型（[具体骨骼类型指标1]）或[具体骨骼类型指标2]之间未发现显著关联。透明矫治器在实现显著的咬合改善方面是有效的，特别是与个性化数字规划以及诸如骨骼锚固等辅助策略相结合时。下颌病例的PAR评分降低幅度更大，这凸显了矫治器在复杂远中移动治疗中的潜力。
