论文摘要
开发从锥形梁计算机断层扫描(CBCT)扫描中获得的人颌的计算模型是耗时且劳动力密集的。此外,由于所涉及的手动任务和缺乏表面/体积网格,文献中无法获得定量比较。我们共享一个从CBCT扫描中获得的人颌骨的17个患者特定有限元元素(FE)模型的开放式存储库,以及用于生成它们的管道。提议的管道最大程度地减少了模型的生成时间和人为干预引起的潜在误差。它具有致密的表面网格,并提供了适合Fe分析的保形表面/体积网格。我们已经量化了开发模型的几何变化,并评估了模型的准确性。 (1)与输入网格的最大偏差,(2)网格质量和(3)模拟结果。我们的结果表明,开发的计算模型是精确的,并且具有适合各种FE场景的质量网格。因此,我们认为该数据集将为未来的人口研究铺平道路。
Developing computational models of the human jaw acquired from cone-beam computed tomography (CBCT) scans is time-consuming and labor-intensive. Besides, a quantitative comparison is not attainable in the literature due to the involved manual tasks and the lack of surface/volumetric meshes. We share an open-access repository of 17 patient-specific finite-element (FE) models of human jaws acquired from CBCT scans and the utilized pipeline for generating them. The proposed pipeline minimizes model generation time and potential errors caused by human interventions. It gets dense surface meshes and provides reduced conformal surface/volumetric meshes suitable for FE analysis. We have quantified the geometrical variations of developed models and assessed models' accuracy from different aspects; (1) the maximum deviations from the input meshes, (2) the mesh quality, and (3) the simulation results. Our results indicate that the developed computational models are precise and have quality meshes suitable for various FE scenarios. Therefore, we believe this dataset will pave the way for future population studies.
