In a previous study, the authors used a finite element analysis (FEA) to evaluate the stresses developed during the loading of an all-ceramic, inlay supported fixed partial denture and compared it with the more traditional full crown supported prosthesis. To date there has been little research into correlating the responses of the numerical model against physical mechanical tests; such validation analysis is crucial if the results from the FEA are to be confidently relied upon. This study reports on the experimental methods used to compare with the FEA and thereby to validate the predictive fracture behaviour of the numerical model. This study also outlines the methods for manufacture and testing of the ceramic structure along with observations of the fracture tests. In addition the procedure used for developing the FEA model for the test system is outlined.
在之前的一项研究中，作者使用有限元分析（FEA）来评估全陶瓷嵌体支持的固定局部义齿加载过程中产生的应力，并将其与更传统的全冠支持的义齿进行比较。迄今为止，很少有研究将数值模型的响应与物理力学测试相关联；如果要自信地依赖 FEA 的结果，那么这种验证分析至关重要。本研究报告了用于与 FEA 进行比较并验证数值模型预测断裂行为的实验方法。本研究还概述了制造和测试陶瓷结构的方法，以及对断裂试验的观察。此外，还概述了用于开发测试系统的 FEA 模型的过程。
