Denture-induced mechanical stress controls bone remodeling.

为了提高老年人义齿的功能和外观，我们对义齿引起的口腔软组织和支撑骨的应力和应变的生物力学意义进行了评估。利用体内测量时-位移关系获得的粘弹性特性和基于锥束CT图像的形态学数据构建患者特异性有限元模型。根据预测的口腔软硬组织内应变积累现象，提出了一种修复治疗的替代设计方案。

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.
