Influence of joint component mechanical properties and adhesive layer thickness on stress distribution in micro-tensile bond strength specimens

The effect of ferrule height on stress distribution within a tooth restored with fibre posts and ceramic crown: A finite element analysis

“…In particular, interfaces post-root canal dentin, post-abutment, abutment-root, abutment-ferrule and abutment-crown were simulated by direct modeling with volumetric elements of the interfacial space between the components. The interface thickness was simulated according to the literature data reporting the average dimensions of composite cement [24] and adhesive [23] layer. The validation process is an important step in a Finite-Elements-Model generation.…”

Bond strength of five dental adhesives using a fracture mechanics approach

“…In addition to the type of adhesive, conditioning prior adhesive application, completeness of resin impregnation of collagen network and test protocol employed (Cho and Dickens, 2004), the adhesion strength to dentine also depends on the dentin health (Ceballos et al, 2003). Since the hybrid layer on the dentine surface itself forms a three-dimensional (3D) layer, its thickness and properties greatly affect the measured bond strength (de Neves et al, 2009;Hashimoto et al, 2002a,b). It has also been shown that the measured bond strength is strongly dependent on the adhesive layer thickness itself (D'Arcangelo et al, 2009;de Neves et al, 2009;Akinmade and Hill, 1992;Akinmade and Nicholson, 1995;Arici et al, 2005).…”

A finite element modelling methodology for the non-linear stiffness evaluation of adhesively bonded single lap-joints: Part 1. Evaluation of key parameters

“…Azari, Papimi and Spelt [27] reported in 2009 that certain researchers had found that increasing t a caused an increase in joint strength [28,29], some observed a strength decrease [5,30,31] and some no significant change at all [31,32]. A second 2009 investigation by Grant et al [26] with joints subjected to four-point bending concluded that the strength was "independent of the adhesive thickness", an "increase in adhesive thickness causes the joint overlap section to be stiffer" and that, for tension loading the strength increases with increased t a .…”
