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…
Abstract Objectives To compare in-vitro micro-shear bond strengths (μSBS) of resin composite to calcium silicate cement (Biodentine™) vs. glass ionomer cement vs. resin modified glass ionomer cement (RM-GIC) using an…
Abstract Objective This study was conducted to determine selected mechanical/physical properties of and monomer release from high-temperature high-pressure (HT/HP) polymerized urethane dimethacrylate (UDMA). Methods Flexural strength ( σ f ),…
Abstract Objectives To test the tensile bond strength of luted composite computer aided design/computer aided manufacturing (CAD/CAM) crowns after use of different adhesive systems combined with different resin composite cements…
Abstract Objective This study aimed to evaluate the effects of the restorative material and cavity design on the facture resistance of inlay restorations under a compressive load using acoustic emission…
Abstract Objectives To develop a method, which is precise, accurate, and insensitive to the angle of inclination for determining the fractal dimensional increment ( D *) of a surface. Methods…
Abstract Objective SrO and SrF 2 are widely used to replace CaO and CaF 2 in ionomer glasses to produce radiopaque glass ionomer cements (GIC). The purpose of this study…
