Relative Microhardness and Flexural Strength of Different Bulk Fill Resin Composite Restorative Materials
Aim: to find out if there is a significant difference in the curing efficiency at the claimed 4 mm depth and in the mechanical properties between the tested pasteform bulk fill resin composite materials. Materials and Methods: Three paste-consistency bulk-fill resin composites were used in this study (Filtek bulk fill3M; X-trafilVoco; and SonicFill bulk-fillKerr). For the microhardness testing,...
متن کاملProperties of dual-cure, bulk-fill composite resin restorative materials.
The purpose of this study was to compare the properties of 2 new dual-cure, bulk-fill restorative composite resins to those of a hybrid composite resin material. Depth of cure, fracture toughness, porosity, microleakage, and volumetric shrinkage properties were examined. With the exception of fracture toughness, significant differences were found among materials. Compared to the incrementally p...
متن کاملDevelopment of metal-resin composite restorative material. Part 4. Flexural strength and flexural modulus of metal-resin composite using Ag-In alloy particles as filler.
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...
متن کاملThe Evaluation of Flexural Strength of Composite Resin Materials with and without Fiber
The aim of the present study was to evaluate the effect of solutions, times of storage and reinforcement with fiber on the flexural strength of different composite materials. Nanofill and nanohybrid composite materials with and without fiber, a glass fiber and polyethylene fiber, were tested in the present study. 72 specimens (25×2×2 mm3) were prepared as following six groups; Group ECME: everS...
متن کاملDevelopment of metal-resin composite restorative material. Part 3. Flexural properties and condensability of metal-resin composite using Ag-Sn irregular particles.
Powder-liquid type metal-resin composites, using Ag-Sn irregular particles as the filler, 4-META as coupling agent and UDMA + TEGDMA as resin matrix, were experimentally prepared under 9 different conditions (three different particle sizes and three different filler contents). The flexural strength and flexural modulus were measured. Three different irregular particle size MRCs without redox-in...
