Wear of Filled and Unfilled Dental Restrain Resins

چکیده
One approach to the study of wear involves the ch~~te~zation of surface failure under conditions of single-pass sliding. Such an approach has been used to show that the wear of commercial and experimental restorative resins and composites is determined by the resistance of the material to penetration and by the mode of deformation during sliding [l] . The purpose of this investigation was to characterize the surface failure of unfilled diacrylate and acrylic resins and to determine the influence of inorganic fiier and a &me coupling agent on the mode of failure of the diacrylate resin under conditions of double-pass sliding. The results were compared with those of single-pass sliding.

Optimizing the concentration of 2,4,6-trimethylbenzoyldiphenylphosphine oxide initiator in composite resins in relation to monomer conversion.
The aim of this study was to optimize the concentration of 2,4,6-trimethylbenzoyldiphenylphosphine oxide (Lucirin® TPO) in unfilled and filled composite resins in relation to the degree of conversion (DC). Increasing concentrations of Lucirin® TPO between 0.05-4.97 wt% were added to equimolar mixtures of Bis-GMA/TEGDMA. Filled resins contained 75 wt% fillers. Standardized samples were cured usi...
متن کاملFracture toughness of composite and unfilled restorative resins.
Fracture toughness, critical strain energy release rate, and critical stress intensity factor were determined for experimental and commercial restorative resins. A composite resin had lower resistance to crack initiation than an unfilled acrylic resin. The data were consistent with surface failure observed in single-pass wear studies of these resins.
متن کاملAn Empirical Equation including Fracture Toughness and Describing Friction of Dental Restorat~e Materials
An equation was developed from studies of single-pass wear and fracture toughness of filled and unfilled dental restorative resins and dental amalgams relating the sliding frictional force F to the normal load N, fracture toughness, modulus of elasticity, yield strength and slider diameter. This equation was of the same form as that reported for viscoelastic materials (F = KW). Friction was cau...
متن کاملSurface failure of commercial and experimental restorative resins.
A single-pass test was used to study the surface failure of commercial and experimental restorative resins and composites. The surface failure observed for unfilled diacrylate resins was more severe than that seen for an unfilled acrylic resin. Addition of nonsilanated filler to the diacrylate resins increased the resistance to penetration but did not dramatically change the mode of surface fai...
