Abstract Objectives Camphorquinone (CQ) is a widely used photoinitiator in dental visible light (VL)-cured resinous materials. However, little is known about the toxicity of CQ in human cells. This study…
Abstract Objectives The objective of this study was to demonstrate a successful binding of Doxy hyclate onto a titanium zirconium alloy surface. Methods The coating was done on titanium zirconium…
Abstract Objectives To analyse the influence of irradiation time, aging before bleaching, and bleaching technique (home bleaching vs. in-office bleaching) on the amount of elutable substances from modern nano-hybrid resin-based…
Abstract Objectives Antibacterial primer and adhesive are promising to inhibit biofilms and caries. Since restorations in vivo are exposed to saliva, one concern is the attenuation of antibacterial activity due…
Abstract Objectives The objectives of this study were to develop a chitosan bilayer membrane containing microspheres with sustained TGF-β 1 release to enhance odontoblast-like cell function in vitro, and to…
Abstract Objective This in vitro study was designed to investigate the influence of the veneer and cyclic loading on the failure behavior of lithium disilicate glass-ceramic (LDG) crowns on maxillary…
Abstract Objectives To synthesize and characterize different molar weight urethane multimethacrylates with a single stage (one-pot) procedure. To prepare and characterize the properties of related composites. Methods Two methacrylate precursors…
Abstract Objective To evaluate the extent and rate of hygroscopic expansion of resin composites at 37 °C. Methods Eight resin composites were examined: 1 micro-hybrid (Bright Light ® ), 5…
Abstract Objective The aim of this study was to develop a novel dental implant abutment with a micro-motion mechanism that imitates the biomechanical behavior of the periodontal ligament, with the…
Abstract Objectives In this work long term stability of a zirconia toughened alumina (ZTA) composite was investigated. Methods Accelerated aging tests under hydrothermal environment, in autoclave and hot water, at…
Abstract Objectives This in vitro study should assess the fracture resistance of veneered zirconia-based crowns with either luted or fused veneer. Methods Thirty-two identical zirconia frameworks (IPS e.max ZirCAD; Ivoclar/Vivadent),…
Abstract Fluorapatite glass-ceramics have been shown to be excellent candidates as scaffold materials for bone grafts, however, scaffold production by sintering is hindered by concurrent crystallization of the glass. Objective,…
Abstract Objectives The residual stress profile developed within the veneering ceramic during the manufacturing process is an important predicting factor in chipping failures, which constitute a well-known problem with yttria-tetragonal-zirconia…
Abstract Objectives Veneered zirconia restorations predominately fail due to veneering fractures. It is hypothesized that a cusp-supporting framework design can prevent these catastrophic failures in all-ceramic restorations. Therefore, we investigated…
Abstract Bioglass 45S5 is a silica-based bioactive glass capable of depositing a layer of hydroxyl carbonate apatite on the surface of the glass when immersed in body fluids. The present…
Abstract Objectives Two types of ceramic coatings on commercially pure titanium for dental implant applications with different Ca/P ratios in the range from 1.5 to 4.0, and two different thicknesses…
Abstract Objective The aim of this study was to (i) obtain the force-related interferometric patterns of loaded dental implant–abutment assemblies differing in diameter and brand using digital holographic interferometry (DHI)…
Abstract During the curing process of light curing dental composites the mobility of molecules and molecule segments is reduced leading to a significant increase of the viscosity as well as…
Abstract Objectives To synthesize a glass–ceramic (GC) that is suitable for non-metallic one-piece dental implant application. Methods Three glasses in a SiO 2 –Al 2 O 3 –CaO–CaF 2 –K…
Abstract Objectives The purpose of this in vitro study was to evaluate the bond strength and durability of adhesive bonding systems to amorphous and crystalline PEKK and fiber-reinforced PEEK using…
