“…Others analyse the results of shear stress at the post-dentine interface, and indicate that this value should be compared to the reported shear bond strengths in order to evaluate the risk of loosing retention Maceri et al, 2009;Pegoretti et al, 2002). Wakabayashi et al (Wakabayashi et al, 2008) also underline the importance of shear stresses to anticipate the probability of failure in the adhesive joints of the restoration. Okamoto et al (Okamoto et al, 2008) used an iterative procedure to account for debonding in the cement layer.…”

“…However, in some realistic situations this analysis is not accurate. Wakabayashi et al (Wakabayashi et al, 2008) cited three main causes of non-linearity: (1) material non-linearities, like the response of the PDL, (2) the changing interrelation of objects, as when loads introduce contacts between components, and (3) geometric nonlinearities, as a consequence of large deformations in some components. In recent years, some works have introduced non-linear FE models as a better way to represent the response of endodontic restorations (Sorrentino et al, 2009;Uddanwadiker et al, 2007).…”

“…The computer gives a discription of each piece of the model, where to be placed when loaded and how much of a load each component will carry, it is used in vitro investigation method for the examination of the complex mechanical behaviors of prostheses and surrounding structures; It is therefore ideally suited for the present study (7,8,9) .…”

The treatment of distal extension base removable partial denture has long been the dilemma of many Prosthodontists, since the support for this type of restoration is based on two functionally different systems, the teeth and associated periodontal membrane and the edentulous ridges. So one of their most elusive goals were to finish the prosthesis by utilizing both systems of support without exposing the tissues to undue stresses which might lead otherwise to bone resorption. Material and method: A two-dimensional finite element analysis method was used to assess the stress distribution on supporting structure where different rest position, including mesial-occlusal rest, distal-occlusal rest, and mesio-distal occlusal rest. The X, and Y coordinate for each node of the model was transferred to the ANSYS program, a load of 10MP was used in this study, where each of the models was subjected to load distributed on the saddle area. Results: Von Mises stress values revealed that, mesial rest produces less stress concentration,

The purpose of this study was to develop and report upon a methodology for a non-linear capacity 3D modeling finite element analysis evaluating the loading behavior of different partial denture designs. A 3D finite element model using human CT data was constructed. An original material constant conversion program was implemented in the data simulation of non-linear tissue behavior. The finite element method material properties of residual ridge mucosa were found to have seven material constants and six conversion points of stress values. Periodontal tissues were found to have three constants, and two conversion points. Three magnetic attachment partial denture designs with different bracing elements were evaluated. Technical procedures for finite element model simulation of nonlinear tissue behavior properties evaluating the oral behavior of prosthetic device designs are reported for prosthodontic testing. The use of horizontal cross-arch bracing positively impacts upon the comparative stability of the partial denture designs tested.
