Abstract: 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.
