| Research Abstract |
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.
