The craniofacial skeleton is designed to withstand the functional forces during mastication. Distribution of these forces is along the stress trajectories that can vary in a cleft skull compared with a normal skull. In this study, the authors constructed finite element models of cleft and normal skull and subjected them for occlusal loading in the posterior teeth. The results showed variation in the trajectories between the models and between the cleft and noncleft sides within the cleft model.
颅面骨骼旨在承受咀嚼过程中的功能作用力。这些力沿着应力轨迹分布，与正常颅骨相比，在腭裂颅骨中应力轨迹可能会有所不同。在本研究中，作者构建了腭裂和正常颅骨的有限元模型，并对其施加后牙咬合负荷。结果显示，模型之间以及腭裂模型中腭裂侧与非腭裂侧之间的轨迹存在差异。
