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…
