To enhance function and appearance in denture-wearing elderly, the biomechanical implications for the denture-induced stress and strain in the oral soft tissues and the supporting bone were evaluated. The viscoelastic properties obtained from the time-displacement relationship in the in vivo measurement and the morphologic data based on the cone beam CT images were used to construct the patient-specific finite element models. Based on the predicted phenomenon of the strain accumulation inside the oral soft and hard tissues, an approach to the alternative design protocol for the prosthodontic treatment was proposed.

为了改善老年人戴义齿后的功能和外观，对义齿引起的口腔软组织和支持骨的应力和应变的生物力学意义进行了评价。根据体内测量中的时间-位移关系和基于锥形束CT图像的形态学数据获得的粘弹性特性用于构建患者特定的有限元模型。基于口腔软、硬组织内部的应变累积现象，提出了一种口腔修复治疗的替代设计方案。
