This paper presents the results obtained by the authors when applying mechanical test methods that are validated using fatigue testing under simulated regime with finite element analysis. In addition to the mostly mandatory physical tests, the simulated regime testing can validate emerging conclusions. Virtual testing conclusions (computer simulated via Cosmos finite element analysis software), strengthen, complement and increase the accuracy of physical test conclusions. During the investigation of the physical test results, there are cases where the simulated physical test is not always explainable. This paper presents a case study conducted on special constructed screws that are subjected to fatigue and verified using the finite element analysis. It presents the possibility for practical application of simulated tests in order to redesign structures that fail during physical tests.

Abstract This study is the first attempt to explore the reason of costochondral graft fracture after lengthy mandible advancement and bilateral coronoidectomy by combining finite element analysis and mechanical test. Eleven groups of models were established to simulate costochondral graft reconstruction in different degrees of mandible advancement, ranging from 0 to 20 mm, in 2 mm increment. Force and stress distribution in the rib-cartilage area were analyzed by finite element analysis. Mechanical test was used to evaluate the resistance of the rib-cartilage complex. Results showed a sharp increase in horizontal force between 8 and 10 mm mandible advancement, from 26.7 to 196.7 N in the left side, and continue increased after 10 mm, which was beyond bone-cartilage junction resistance according to mechanical test. Therefore, we concluded that bilateral reconstruction with coronoidectomy for lengthy mandible advancement (≥ 10 mm) may lead to prominent increase in shear force and result in a costal-cartilage junction fracture, in this situation, alloplastic prosthesis could be a better choice. We also suggested that coronoidectomy should be carefully considered unless necessary.
