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…
