Fissure sealant materials: Wear resistance of flowable composite resins
Background. Wear resistance of pit and fissure sealant materials can influence their retention. Wear characteristics of sealant materials may determine scheduling of check-up visits. The aim of this study was to compare wear resistance of two flowable composite resins with that of posterior composite resin materials. Methods. Thirty-five disk-shaped specimens were prepared in 5 groups, includin...
متن کاملWear Resistance of Bulk-fill Composite Resin Restorative Materials Polymerized under different Curing Intensities.
INTRODUCTION The aim of this study was to assess the wear resistance of four bulk-fill composite resin restorative materials cured using high- and low-intensity lights. MATERIALS AND METHODS Twenty-four samples were prepared from each composite resin material (Tetric N-Ceram, SonicFill, Smart Dentin Replacement, Filtek Bulk-Fill) resulting in a total of 96 samples; they were placed into a mol...
متن کاملMicrostructural Characterisation and Wear Behaviour of Diamond Composite Materials
Since the initial research leading to the production of diamond composite materials, there have been several important developments leading to significant improvements in the properties of these superhard composite materials. Apart from the fact that diamonds, whether originating from natural resources or synthesised commercially, are the hardest and most wear-resistant materials commonly avail...
متن کاملWear test of composite restorative materials by a polishing machine.
The wear resistance of microfilled and conventional composite resins, was examined, using two sizes of abrasive particles for polishing. The mechanical properties of the composite resins were also studied and evaluated in relation to wear. Conventional composites showed much lower wear resistance than the microfilled resins. The amalgam and human enamel abraded with 10ƒÊm SiC particles, had str...
متن کاملAccelerated wear testing of PTFE composite bearing materials
Hertzian line contact stresses between a rotat ing metal cy l inder and a reciprocating f lat str ip of the bearing material are used in an accelerated wear test described in this paper. The test readi ly demonstrates differences in the wear behaviour between d i f ferent PTF E-based dry bearing materials. For one widely-used woven PTFE f ibre composite, the relat ionships between wear and stre...
