STATEMENT OF PROBLEM Techniques and recommendations for the restoration of endodontically treated teeth have changed from the use of custom cast metal post and core system to glass fiber-reinforced (GFRC) post and composite core system. Has this latest prefabricated glass fiber reinforced post and composite core system increased the fracture resistance of teeth and reduced the incidence of unre...

objective: the aim of this study was to compare the microtensile bond strengths (μ tbs) of three core materials with one lithium disilicate reinforced ceramic using two resin cements. methods: three core materials (nulite f® (biodental technologies), filtek z250® (3m-espe), prettau-anterior® (zirkonzhan, germany)) were prepared as blocks (10×10×4 mm3) according to the manufacturer’s instruction...

Statement of problem. The optimal luting material for fiber-reinforced posts, to ensure the longevity of foundation restorations, remains undetermined. Purpose. The purpose of this study was to evaluate the suitability of 3 dual-polymerizing resin cements (DRCs) and 2 dual-polymerizing foundation composite resins (DFCRs) for luting fiber-reinforced posts by assessing their Knoop hardness number...

The flexural strength and flexural modulus of an experimental metal-resin composite, which used Ag-In alloy particle as the filler, were evaluated. The effect of acid treatment and heat treatment on the Ag-In alloy particle was investigated. The flexural strength of the experimental metal-resin composites ranged from 65.5 MPa to 91.0 MPa. The flexural strength of the metal-resin composite incre...

The main purpose of this study is an experimental investigation and comparison the mechanical properties pultruded glass fibre reinforced polymer composite based on polyester vinylester resin. For purpose, specimens were cut from walls square tube profile along to fibres direction. such as ultimate tensile strength bending strength, modulus flexural obtained. It was observed that using vinyl es...

This paper investigated the moisture absorption, mechanical behavior and the dielectric performance of hybrid and non-hybrid polymeric composites. Hand lay-up technique was used for processing carbon; glass reinforced polyester resin composites (non-hybrid) and carbon-glass/polyester hybrid composites with various fiber configurations. The maximum resistance of water absorption was obtained for...
