Retention is the phase of orthodontic treatment which maintains teeth in their orthodontically corrected positions, following the cessation of active orthodontic tooth movement. Development of resin-impregnated, fiber-reinforced composite materials has provided the potential to develop new approaches for stabilizing teeth and replacing teeth conservatively. This case report describes the rehabi...

Microstructured optical fibers MOFs represent a promising platform technology for fully integrated photonic-plasmonic devices. In this paper, we experimentally investigate the properties of two MOF templates impregnated with silver nanoparticles via a high pressure chemical deposition technique. By comparing fiber templates with different air filling fractions, we have quantified the importance...

Cr (III) removal from aqueous solutions by sorption in a fixed bed column filled with alizarin S impregnated hemp fibers has been studied. The effect of the initial metal ion concentration on the Cr (III) sorption process was investigated and the experimental breakthrough curves were obtained. The breakthrough time and saturation time decreased from 110 min to 80 min and from 300 min to 160 min...

The aim of this study was to evaluate the effect of reinforcing polyaromatic polyamide (aramid) fibers with various orientations on the flexural properties of denture base resin. Aramid fibers with four orientations of unidirectional, woven, non-woven and paper-type were pre-impregnated and placed at the bottom of a specimen mold. Heat-polymerized denture base resin was packed over the fibers a...

The questions of research physical and chemical characteristics reinforcing tapes, peculiarities connection composite material component the splint, indicators strength their connection, optimal thickness for tape covering remain not fully studied require further work in this direction order to optimize splinting stages mobile teeth various clinical situations nosological forms dise...

fi ber reinforced plastic (FRP) re. nforcement is one of the most promising new developments for concrete structures. FRP reinforcing elements provide lighter, easier to assemble, and more durable structures that are free of the deterioration caused by corrosion of steel. FRPs consist of synthetic or organic highstrength fibers, most of which are impregnated with a resin matrix. They are availa...

Micromechanical physics of critical fiber length, describing a minimum filament distance for resin impregnation and stress transfer, has not yet been applied in dental science. As a test of the hypothesis that 9-micron-diameter, 3-mm-long quartz fibers would increase mechanical strength over particulate-filled composites, photocure-resin-pre-impregnated discontinuous reinforcement was incorpora...

With the rapid development of high-performance fibers such as carbon, enhanced glass in structural applications, use fiber-reinforced composite (FRC) materials has also increased many areas. Liquid molding (LCM) is a widely used manufacturing process manufacturing; however, impregnation resin reinforcing during processing poses significant issue. The optimization related to tow deformations fib...

STATEMENT OF THE PROBLEM Sufficient adhesion between silorane/methacrylate-based composites and methacrylate impregnated glass fiber increases the benefits of fibers and enhances the mechanical and clinical performance of both composites. PURPOSE The aim of this study was to evaluate the compatibility of silorane and methacrylate-based composites with pre-impregnated glass fiber by using flex...
