Although with increasing popularity due to aesthetic appeal and comfort, clear aligners (CAs) are facing challenges in efficacy and predictability. Advancement in the underlying biomechanical field is crucial to addressing these challenges. This paper endeavors to provide a comprehensive framework for understanding the biomechanics of CA and enlightening biomechanics-based improvements on treatment strategies.
A thorough review of the English-language literature accessible through PubMed and Google Scholar, without any publication year restrictions, was undertaken to unravel the biomechanical aspects of CA.
This review presented an up-to-date understanding of aligner biomechanics arranged by the framework of the material-dependent mechanical characteristics of CA, the geometric characteristics-dependent force transmission of the CA system, methods for studying the biomechanics of CA, and the biomechanical analyses for different types of tooth movement.
Biomechanics should be the fundamental concern for concepts, methods and adjuncts attempting to enhance the accuracy and predictability of tooth movement induced by CA. Improvement on material properties and alteration of geometric design of CA are two main approaches to develop biomechanically optimized force system. Exploration of real-world force sensing and monitoring system would make substantial progresses in aligner biomechanics.
尽管由于美观和舒适，透明牙套（CA）越来越受欢迎，但在疗效和可预测性方面仍面临挑战。基础生物力学领域的进步对于解决这些挑战至关重要。本文旨在为理解 CA 的生物力学提供一个全面的框架，并为基于生物力学的治疗策略提供启示。
通过 PubMed 和 Google Scholar 对可获得的英文文献进行全面综述，不限制任何出版年份，以揭示 CA 的生物力学方面。
本综述按照 CA 的材料相关力学特性、CA 系统的几何特性相关力传递、CA 生物力学研究方法以及不同类型牙齿移动的生物力学分析的框架，呈现了对牙套生物力学的最新理解。
生物力学应该是试图提高 CA 诱导牙齿移动准确性和可预测性的概念、方法和辅助手段的基础关注点。改善材料性能和改变 CA 的几何设计是开发生物力学优化力系统的两个主要方法。探索现实世界的力感测和监测系统将使牙套生物力学取得实质性进展。
