The integration of orthodontic therapy with periodontal considerations remains a critical area in dental science, particularly as periodontal support degradation poses significant challenges to effective load distribution during tooth movement. This conceptual manuscript proposes a novel theoretical framework for computationally simulating the progressive degradation of periodontal structures and its influence on orthodontic force dynamics. Drawing on biomechanical principles, the framework conceptualizes the periodontal ligament as a viscoelastic interface that modulates stress transmission, with degradation modeled through parametric alterations in tissue properties such as stiffness and damping coefficients. Literature synthesis from recent studies highlights the limitations of existing models, which often overlook the heterogeneous nature of degradation processes across different periodontal zones. The proposed framework introduces a layered, multi-phase approach that accounts for spatial variations in alveolar bone loss and ligament fiber disorganization, enabling a more nuanced prediction of load redistribution patterns. By theorizing degradation as a continuum of microstructural changes, the model elucidates how diminished support amplifies localized stresses, potentially exacerbating orthodontic complications. This theoretical construct aims to guide future modeling efforts, emphasizing the need for integrated simulations that bridge periodontal pathology and orthodontic biomechanics. Ultimately, it underscores the potential for enhanced conceptual understanding to inform interdisciplinary strategies, fostering advancements in theoretical orthodontics and periodontics without empirical validation.
