摘　　要：口腔正畸治疗中,牙齿的移动依赖于矫治力产生的牙周膜(Periodontal Ligament,PDL)反应,PDL的生物力学性质是正确理解正畸牙移动、牙周组织响应和制定正畸治疗计划的关键和基础。由于PDL组成成分多、牙根形态各异,对其生物力学性质的研究较为困难。该文拟对近年来研究PDL生物力学性质的各种试验方法做一综述。Successful orthodontic tooth movement depends on favorable responses from the periodontal ligament（ PDL） under orthodontic forces.Thus the biomechanical properties of the PDL are of great importance for understanding the mechanisms of orthodontic tooth movement and periodontal tissue response and making appropriate treatment plans.However,the complexity of the PDL components,together with large variations of root morphological characteristics,makes it a rather formidable challenge for studying the biomechanical properties of the PDL.Optimal experimental methods and properly designed parameters are often needed to establish a constitutive model for such studies.In this paper,the experimental methods that have been used to study the biomechanical properties of PDL were reviewed.
