“…An encouraging recent study validated the results of mechanical tests of milled ceramic bars against an FEM, a process reversed from this current study 5 . This study demonstrates that under simplistic conditions, the results of FEAs cannot only be precise but indeed more reliable.…”

“…Earlier validation studies have been quite rudimentary in their methodology, with little regard given to matching elastic moduli or realistic geometry; later studies are increasingly adopting realistic experimental designs with greater consideration given to matching material properties. However, there appears to still be absent accurate geometry, scale materials and loading conditions 3–9 …”

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.Keywords: All-ceramic bridge, inlay fixed partial denture, experimental design, finite element analysis.Abbreviations and acronyms: CAD ⁄ CAM = computer-aided design ⁄ computer-aided milling; CR = composite resin; FEA = finite element analysis; FPD = fixed partial denture; PDL = periodontal ligament; Y-TZP = yttria stabilized tetragonal zirconia.

“…For a better approach, the results from both FE and mechanical testing should be obtained. Together they offer more reliable data than one of these methods alone . Therefore, mechanical investigation of FDPs under the same conditions as in this analysis is necessary.…”

“…It is known that the Von Mises criterion is only valid for the ductile materials with equal compressive or tensile strength, but materials exhibiting brittle behavior such as ceramics, cements or resin composites presents reported values of compressive strength significantly greater than tensile strength [20]. Positive and negative values indicate that the corresponding regions are subjected to tensile or compressive stresses (figure 5) [21].…”
