Clear aligner therapy (CAT) has progressed from a niche adjunct to a dominant modality in contemporary orthodontics. This manuscript frames that trajectory as a sequence of scientific-revolution stages—pre‑science, normal science, model drift, model crisis, and model revolution—to clarify how conceptual and technological shifts have reshaped clinical practice and research priorities. We synthesize developments in digital workflows (intraoral scanning, CBCT integration), AI‑driven treatment staging, and personalized biomechanics, and we evaluate methodological limitations in current CAT studies that hinder reliable data interpretation. Key gaps include inconsistent outcome definitions, limited external validity of small or vendor‑sponsored trials, insufficient biomechanical and materials characterization, and sparse patient‑centered endpoints. These limitations inflate uncertainty around dose–response relationships, material behaviour under clinical conditions, and the real‑world effectiveness of algorithmic staging tools. To enhance evidence quality and patient outcomes, we propose stronger research designs—prospective, adequately powered, multi-center trials; standardized outcome metrics; preregistration and transparent data sharing; robust biomechanical and materials testing; and integrated health‑services research to assess access, costs, and patient preferences. We also advocate development and validation of AI‑assisted decision‑support tools within rigorous clinical frameworks. Multidisciplinary, methodologically rigorous research and consensus on outcomes are essential to translate digital innovations in CAT into predictable, patient‑centred care. Implementing improved study designs and transparent practices will better define effective protocols, guide policy, and ultimately improve clinical outcomes for patients receiving clear aligner therapy.

清除矫正器治疗（CAT）已经从一个利基辅助发展成为当代正畸的主导模式。这篇手稿框架的轨迹作为科学革命阶段的序列-前科学，正常科学，模型漂移，模型危机和模型革命-澄清概念和技术转变如何重塑临床实践和研究重点。我们综合了数字工作流程（口内扫描、CBCT集成）、人工智能驱动的治疗分期和个性化生物力学的发展，并评估了当前CAT研究中阻碍可靠数据解释的方法学局限性。主要的差距包括不一致的结局定义，小型或供应商赞助的试验的有限外部有效性，不充分的生物力学和材料表征，以及稀疏的以患者为中心的终点。这些限制增加了剂量-反应关系、临床条件下的材料行为以及算法分期工具在现实世界中的有效性的不确定性。为了提高证据质量和患者预后，我们建议加强研究设计——前瞻性、充分支持的多中心试验；标准化结果指标；预登记和透明的数据共享；稳健的生物力学和材料测试；以及综合卫生服务研究，以评估获取、成本和患者偏好。我们还提倡在严格的临床框架内开发和验证人工智能辅助决策支持工具。多学科、方法严谨的研究和对结果的共识对于将CAT的数字创新转化为可预测的、以患者为中心的护理至关重要。实施改进的研究设计和透明的实践将更好地定义有效的方案，指导政策，并最终改善接受明确对准剂治疗的患者的临床结果。

Clear aligner therapy has become increasingly popular due to its esthetic and comfort advantages. However, its predictability in certain tooth movements, particularly rotations, is limited compared to fixed appliances. This article explains the biomechanical differences between fixed appliances and clear aligners, highlighting the influence of tooth geometry and aligner-tooth interface dynamics on treatment outcomes. It also explores the impact of unintended movements and the need for open contacts to facilitate rotations. By understanding these biomechanical details and considering innovative attachment designs and movement planning strategies, clinicians can enhance the predictability and effectiveness of clear aligner therapies.

由于其美观和舒适的优点，透明矫正器疗法越来越受欢迎。然而，与固定矫治器相比，它在某些牙齿运动，特别是旋转时的可预测性是有限的。本文解释了固定矫治器和透明矫治器之间的生物力学差异，强调了牙齿几何形状和矫治器-牙齿界面动力学对治疗结果的影响。它还探讨了意外运动的影响以及开放接触以促进旋转的必要性。通过了解这些生物力学细节，并考虑创新的附着设计和运动规划策略，临床医生可以提高透明对准器治疗的可预测性和有效性。

Individuals commonly use the internet as a source of healthcare information. Clear aligner therapy (CAT) is frequently prescribed for the management of malocclusion. The aim of this review was to collate and synthesize the literature concerning the quality of information (QOI) regarding CAT on the internet. This scoping review was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Eighteen studies were identified for inclusion following a systematic search of four databases and screening of publications by two independent reviewers. Most studies (n = 13) evaluated the QOI on social media platforms (SMPs) with five studies determining the QOI of website content. YouTube was the SMP through which relevant communicated information was most assessed. There was considerable variance in the methodologies employed to determine the QOI in the studies. The QOI related to CAT was generally poor-to-moderate on the internet. Poor QOI was a finding related to direct-to-consumer aligners. Details regarding high- and low-quality information were limited. Where documented, high-quality items included benefits of treatment and low-quality items included quality-of-life issues. Evaluation of content in the English language only was a self-reported limitation of the authors of many studies and therefore, a limitation of the present review. Several studies advised that clinicians should be aware of pertinent content communicated through SMPs.

个人通常使用互联网作为医疗保健信息的来源。清除矫正器治疗（CAT）是治疗错牙合的常用方法。本综述的目的是整理和综合有关网上CAT信息质量（QOI）的文献。该范围评价是按照系统评价的首选报告项目和范围评价的元分析扩展指南进行的。经过对四个数据库的系统检索和两位独立审稿人对出版物的筛选，确定了18项研究纳入。大多数研究（n = 13）评估了社交媒体平台（SMPs）的QOI，其中5项研究确定了网站内容的QOI。YouTube是评估相关传播信息最多的SMP。在研究中，用于确定QOI的方法存在相当大的差异。互联网上与CAT相关的qi一般为差至中等。较差的QOI是与直接面向消费者的校准器相关的发现。关于高质量和低质量信息的细节有限。在记录中，高质量的项目包括治疗的益处，低质量的项目包括生活质量问题。仅用英语评价内容是许多研究作者自我报告的局限性，因此也是本综述的局限性。一些研究建议临床医生应该了解通过smp传达的相关内容。

Orthodontic treatment with clear aligner therapy (CAT) faces challenges in real-time adjustments compared to fixed appliances. CAT limitations, such as predictability and efficacy, are well-documented, raising questions about treatment outcomes and defining "ideal" results in a commercialized context. If we condone inadequate standards in Orthodontics, we undermine the integrity of our profession, jeopardizing patient outcomes and potentially driving them towards unqualified alternatives. Challenges can be addressed by utilizing skeletal anchorage methods like Temporary Anchorage Devices (TADs), and integrating CAT with complementary treatments for improved efficacy. Miniscrew skeletal anchorage complements aligners by providing additional support for tooth movement. However, excessive forces from mini-screws can disrupt aligner guidance, requiring caution during treatment. Part I of the paper focuses on limiting factors and sagittal corrections elaborated with CAT, while Part II of this series covers vertical and transverse applications with a special focus on interdisciplinary treatment modalities. Ample cases for each scenario were included.

与固定矫治器相比，使用透明矫正器治疗正畸在实时调整方面面临挑战。CAT的局限性，如可预见性和疗效，是有案可查的，这引发了对治疗结果的质疑，并在商业化背景下定义了“理想”结果。如果我们纵容不充分的正畸标准，我们就会破坏我们职业的诚信，危及患者的治疗结果，并可能驱使他们选择不合格的替代品。可以通过使用临时锚固装置（TADs）等骨骼锚固方法来解决这些挑战，并将CAT与补充治疗相结合以提高疗效。微型骨锚通过提供额外的支持牙齿运动补充对准器。然而，来自微型螺钉的过大力量可能会破坏对准器的引导，因此在治疗过程中需要谨慎。论文的第一部分侧重于限制因素和矢状面校正，而本系列的第二部分涵盖了垂直和横向应用，特别关注跨学科的治疗方式。每个场景都包含了示例案例。

Anterior open bites represent one of the most complex malocclusions to treat due to their multifactorial etiology and high risk of relapse. While traditionally managed with fixed appliances, extractions, temporary anchorage devices (TADs), or surgery, clear aligner therapy has emerged as an effective alternative for adult patients when biomechanics are properly applied. Anterior open bite correction with clear aligners occurs primarily through incisor extrusion, with limited and less predictable contributions from molar intrusion. This paper reviews current knowledge on anterior open bite correction with clear aligners, the predictability of relevant tooth movements, and clinical outcomes reported in the literature. It also presents a contemporary clinical protocol for managing anterior open bite with clear aligners, including setup strategies in the digital treatment plan, class-specific considerations, staging, and retention.

由于其多因素病因和高复发风险，前开咬是最复杂的牙合治疗之一。虽然传统上使用固定器械、拔牙、临时锚固装置（TADs）或手术治疗，但当生物力学正确应用时，明确对准器治疗已成为成人患者的有效替代方法。前路开放咬合矫正主要通过门牙挤压进行，磨牙侵入的作用有限且不可预测。本文回顾了目前关于使用清晰对准器进行前牙开咬矫正的知识，相关牙齿运动的可预测性以及文献报道的临床结果。它还提出了一种现代临床方案，用于管理使用透明矫正器的前牙开咬，包括数字治疗计划中的设置策略，特定类别的考虑因素，分期和保留。

The range of malocclusions treatable with aligners has expanded, yet complex cases still often require auxiliaries or skeletal anchorage to achieve predictable results. Temporary anchorage devices are often used at different stages of treatment to achieve distinct objectives, a practice that typically requires multiple appliances. This, in turn, increases treatment costs, prolongs therapy due to interruptions while awaiting new devices, and introduces additional clinical challenges. We propose and describe an alternative approach: a modular orthodontic system based on skeletal anchorage, designed to perform multiple movements within a single framework. This system allows for sequential activation of components as needed, without the need for appliance replacement. To illustrate its characteristics, advantages, and limitations, we present two clinical case reports.

可以用矫正器治疗的错颌的范围已经扩大，但复杂的病例仍然经常需要辅助或骨骼锚固来达到可预测的结果。临时锚固装置通常在治疗的不同阶段使用，以达到不同的目的，这种做法通常需要多个装置。这反过来又增加了治疗成本，在等待新设备的过程中由于中断而延长了治疗时间，并带来了额外的临床挑战。我们提出并描述了一种替代方法：基于骨骼锚固的模块化正畸系统，设计用于在单个框架内执行多个运动。该系统允许按需顺序激活组件，而无需更换设备。为了说明其特点，优点和局限性，我们提出两个临床病例报告。

Introduction

Interproximal reduction (IPR) is a commonly used modality in orthodontic treatment and is often integrated into digital treatment planning (DTP) processes prior initiating clear aligner therapy (CAT). Despite its apparent widespread use, existing research has primarily focused on general effects and the risks of IPR in orthodontics, with limited appraisal of its use with CAT.

Objective

This scoping review aimed to collate and synthesise the evidence regarding the use of IPR with CAT, focusing on its applications, effects, and perceptions among clinicians and patients.

Methods

The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. On 29th August 2024, an electronic search was conducted across five databases using controlled vocabulary and free-text keywords. In addition, hand searches of key orthodontic journals, reference lists, and systematic reviews, and a search of the grey literature search was performed. Study selection, data extraction, and data synthesis were carried out using a systematic approach.

Results

Thirty-one studies, including retrospective observational studies, prospective interventional trials, and clinician surveys were collated and synthesised. The results were categorised into five groups: surveys on clinical use (six studies), patient and clinician perceptions (four studies), clinical studies on its application (six studies), effects (nine studies), and the accuracy of IPR within the context of CAT (eight studies). The findings were presented in both text and tabular formats.

Conclusions

This review highlighted the widespread use of IPR in CAT and its employment in DTP processes. Findings regarding its clinical applications, associated outcomes, and the perceptions of clinicians and patients were varied. The importance of technical precision and the need for further high-quality research to refine protocols and enhance treatment outcomes were frequently emphasized.

Registration

This review was registered in the Open Science Framework database (https://osf.io/nrkmy).

近端复位（IPR）是正畸治疗中常用的一种方式，通常在开始清晰对准器治疗（CAT）之前整合到数字治疗计划（DTP）过程中。尽管其明显广泛使用，但现有的研究主要集中在IPR在正畸中的一般效果和风险，对其与CAT的使用评估有限。目的：本综述旨在整理和综合有关知识产权在CAT中使用的证据，重点关注其应用、效果和临床医生和患者的看法。方法本综述遵循系统评价首选报告项目和荟萃分析扩展范围评价（PRISMA-ScR）指南。2024年8月29日，使用受控词汇和自由文本关键字对五个数据库进行了电子搜索。此外，手工检索了关键的正畸期刊、参考文献列表和系统综述，并进行了灰色文献检索。采用系统的方法进行研究选择、数据提取和数据合成。结果整理和综合31项研究，包括回顾性观察性研究、前瞻性介入试验和临床医生调查。结果分为五组：临床使用调查（六项研究），患者和临床医生的看法（四项研究），其应用临床研究（六项研究），效果（九项研究），以及知识产权在CAT背景下的准确性（八项研究）。调查结果以文本和表格两种格式提出。结论知识产权在CAT中的广泛应用及其在DTP过程中的应用。关于其临床应用、相关结果以及临床医生和患者的看法的发现各不相同。技术精确性的重要性以及进一步开展高质量研究以完善方案和提高治疗效果的必要性经常得到强调。本综述已在Open Science Framework数据库（https://osf.io/nrkmy）中注册。
