Abstract Objectives To analyze marginal integrity of resin composites dental restorations using optical coherence tomography (OCT). Methods Thirty extracted human premolars had occlusal cavities prepared and were randomly divided according…
Abstract Objectives To develop an enhanced, reproducible and discriminatory biocompatibility testing model for non-precious dental casting alloys, prepared to a clinically relevant surface finishing condition, using TR146 oral keratinocyte cells….
Abstract Objective Chipping failures observed clinically in bilayer systems of porcelain and zirconia restorations should be coupled with a monoclinic to tetragonal phase transformation in the zirconia layer due to…
Abstract Objectives The aim was to evaluate the stress distribution, comparing an anterior sound tooth with post-endodontic restored teeth under mechanical loading. Methods A three-dimensional finite element analysis was performed…
Abstract Objectives CAD/CAM-technologies aim for a standardized, accurate production of dental restorations out of high strength materials (zirconia). The three-dimensional internal fit of CAD/CAM-manufactured zirconia copings was evaluated in vitro…
Abstract Objectives Chewing simulators are used for preclinical evaluation of newly developed dental restorative materials. To guarantee the independence of test conditions, contact forces during chewing simulation should be independent…
Abstract Objectives The purpose of this study was to evaluate the cantilever-bending test as a bond-strength measurement method for enamel/composite adhesion. Materials and methods The buccal surface of bovine incisors…
Abstract Objective To evaluate the effect of the specimen design on the flexural strength ( σ f ) and failure mode of ceramic structures, testing the hypothesis that the ceramic…
Abstract Objectives Surface conditions are of interest in all-ceramic restorations since they can control both bonding and strength. Tensile testing methods are commonly used to evaluate surface conditions of ceramics….
Abstract Objectives The aim of the present study was to compare, in situ , the initial dental plaque formation on a recently developed silorane-based composite resin, Filtek Silorane, and on…
Abstract Objective To improve its mechanical performance, structural optimization had been used in a previous study to obtain an alternative design for a 3-unit inlay-retained fiber-reinforced composite (FRC) dental bridge….
Abstract Objectives The purpose of this study was to characterize the surface morphology and the elastic properties of four dental restorative flowable composites currently on the market (Venus Diamond Flow,…
Abstract Objective This study evaluated the effect of different chemical surface treatments on the surface characteristics of commercially pure titanium (cp Ti) and the adhesion of the porcelain–titanium system by…
Abstract Objectives To compare the crystalline phases present, quantify the adhesion to zirconia and measure the mechanical properties of four commercially available pressed ceramics suitable for zirconia substructures. Materials and…
Abstract The variability in methods and outcomes of bond strength testing reports is well documented in the dental literature. Many studies lack important information, which impairs the ability to reproduce…
