The alveolar bone plays a pivotal role in orthodontic tooth movement (OTM), where mechanical forces induce remodeling that facilitates tooth displacement. However, the specific influence of alveolar bone architecture—encompassing cortical thickness, trabecular patterning, and overall density—on distinct patterns of tooth displacement remains underexplored in a unified theoretical context. This conceptual manuscript proposes a novel framework, termed the Alveolar Bone Displacement Susceptibility Model (ABDSM), which integrates biomechanical principles with bone adaptive responses to delineate how variations in bone architecture predispose teeth to specific displacement modes, such as tipping, bodily translation, or rotational shifts. Drawing from recent literature on bone microarchitecture and mechanotransduction, the framework posits that denser cortical layers may favor controlled translational movements by providing uniform resistance, whereas sparse trabecular networks could amplify tipping tendencies due to anisotropic stress distribution. This model emphasizes the interplay between inherent bone structural heterogeneity and applied orthodontic forces, offering a predictive lens for understanding variability in OTM outcomes without invoking empirical data. By synthesizing theoretical insights publications, the ABDSM advances orthodontic theory by highlighting architecture-dependent pathways in bone remodeling, potentially informing future conceptual refinements in periodontal-orthodontic interfaces. Ultimately, this framework underscores the need for architecture-aware approaches in conceptualizing OTM dynamics.
