口腔生物力学是口腔正畸学的重要基础学科之一。在传统正畸力学系统稳定运行的基础上，矫治理念仍在不断更新发展，随着各类新型矫治器不断研发、矫治技术不断提出，对不同矫治体系的生物力学效应探索是正畸领域的关注重点。口腔生物力学技术的不断优化、突破与创新也为更加真实模拟和理解矫治中的生物力学效应提供了重要途径。本文主要对近年来固定矫治、隐形矫治、矫形治疗3个矫治体系相关的生物力学研究进行综述，包括正畸新理念和正畸新技术的生物力学分析、生物力学新技术在正畸中的应用等。

Oral biomechanics, an important fundamental discipline within orthodontics, continually evolves and expands upon traditional orthodontic mechanical systems. As advancements in new orthodontic devices and techniques persist, interest within the field progressively focuses on the investigation of biomechanical effects of various orthodontic systems. Furthermore, relentless optimization, innovation, and breakthroughs in oral biomechanics technology offer an essential pathway to simulate and understand the biomechanical impacts within orthodontic treatment more accurately. This review primarily summarized the research development from the recent years across three principal orthodontic treatment systems: fixed orthodontics, invisible orthodontics, and orthopedic treatment, including orthodontic concepts, emergence of new technologies, and implementations of novel biomechanical techniques within these systems.
