Abstract: In recent years，finite element analysis has garnered significant attention in the field of periodontal ligament mechanical modeling，becoming a crucial tool for studying its complex mechanical behavior. The periodontal ligament，as a key tissue connecting teeth to alveolar bone，exhibits pronounced viscoelastic and nonlinear properties in its mechanical responses. Within its structure，the fibrous phase primarily resists tensile forces，while the fluid phase imparts distinctive viscoelasticity and time-dependent behavior. However，further elucidating the dynamic mechanical properties of the periodontal ligament and optimizing finite element modeling approaches remain focal points and hot topics in current researches. Therefore，this paper aims to systematically review the research progress on the dynamic mechanical properties of the periodontal ligament and its finite element modeling，providing references and insights for related fields.
