Optimization of the arrangement of artificial molars on complete dentures was performed with finite element analysis. The result for the arrangement of artificial molars on mandibular dentures showed that the occlusal surface should be parallel to the alveolar ridge surface below them. As to maxillary and mandibular complete dentures, the result depended on the response variable : maximum chewing efficiency in a specific teeth, or maximization of the lowest chewing efficiency of all teeth. The method in this study was considered to have a potential usefulness for the determination of the arrangement of artificial teeth.

通过有限元分析，对人工磨牙的排列进行了优化。在下颌义齿上排列的人造磨牙的结果表明，咬合表面应平行于其下方的肺泡脊表面。至于上颌和下颌完整义齿，结果取决于响应变量：特定牙齿的最大咀嚼效率或所有牙齿最低咀嚼效率的最大化。这项研究中的方法被认为对确定人造牙齿的排列具有潜在的有用性。
