The purpose of this study was to investigate the deformation and flexural properties of acrylic and urethane polymers reinforced with glass fiber sheet. Four types of specimen — self-curing resin plate (R) , light-curing oligomer plate containing a reinforcement (GO) , and self-curing resin plate containing a reinforcement on one (GR) or both (GRG) sides — were prepared with three thicknesses: ...
Characterizing how cells in three-dimensional (3D) environments or natural tissues respond to biophysical stimuli is a longstanding challenge in biology and tissue engineering. We demonstrate a strategy to monitor morphological and mechanical responses of contractile fibroblasts in a 3D environment. Cells responded to stretch through specific, cell-wide mechanisms involving staged retraction an...
BACKGROUND The interim restoration is an important phase in fixed prosthodontic therapy. It should provide sufficient durability to withstand the forces of mastication. A fractured interim restoration is damaging to the prosthodontic care and may lead to an unscheduled appointment for repair. Several attempts have been made to reinforce interim fixed partial dentures (FPDs). These have included...
Self?reinforced polymer composites: An opportunity to recycle plastic wastes and their future trends
Polymers and their composites have played an important role in industrial development. Polymer are becoming much stronger more competitive than other materials as a result of ongoing research This was made possible by newly developed techniques that could alter the physical chemical properties constituents. One them is self-reinforcement technique, which allows for fabrication high-strength the...
