Abstract Objectives Maxillofacial silicone elastomers are used to replace facial parts lost through disease or trauma. However, these materials do not possess ideal properties. The purpose of this study was…
Abstract Objective The aim of this investigation was to determine the effect of an experimental liquid rubber (LR) toughening agent on fracture toughness, crosslink density and Barcol hardness of polymerized…
Abstract Objective To evaluate the effects of clinically relevant variables on the maximum principal stress (MPS) in the veneer layer of an anatomically correct veneer–core–cement–tooth model. Methods The average dimensions…
Abstract Objective One of the limitations of resin cements and flowable dental composites is their poor mechanical properties such as low flexural strength and fracture resistance under body conditions. The…
Abstract Objective To investigate the effect of irradiance through choice of LED light-curing unit (LCU) and fiber-optic tip on the mechanical properties of methacrylate resin-based composites (RBCs). Methods Rectangular bar-shaped…
Abstract Objectives This investigation evaluated the flexural properties of two composite resins, and the influence of unidirectional glass fiber reinforcements, with and without pre-tensioning. Methods Two composite resins (Q: Quixfil…
Abstract Objective This study aims to validate a cavity shape optimization approach for improving the debonding resistance of dental restorations by carrying out fracture tests on restored model teeth with…
Abstract Objective The objective of this study was to test the null hypothesis that the interfacial toughness of each of two types of bonded core-veneer bilayer ceramics is not significantly…
Objectives : To evaluate the bond strength of conventional and self-adhesive resin cements to a yttrium-oxide-stabilized polycrystalline tetragonal zirconia ceramic (YTZP) considering 3 factors ( cement in 4 levels [Panavia…
Objectives : The Rocatec system conditions the bonding surface by fusing a unique silica layer onto the surface. The purpose of this study is to determine the effect of Rocatec…
