Available in PDF, EPUB and Kindle. Book excerpt: * It has been rumored that a bumble bee has such aerodynamic deficiencies that it should be incapable of flight. Fiberglass-reinforced polymer com posites, similarly, have two (apparently) insurmountable obstacles to per formance: 1) Water can hydrolyze any conceivable bond between organic and inorganic phase, and 2) Stresses across the interface during temperature cycling (resulting from a mismatch in thermal expansion coefficients) may exceed the strength of one of the phases. Organofunctional silanes are hybrid organic-inorganic compounds that are used as coupling agents across the organic-inorganic interface to help overcome these two obstacles to composite performance. One of their functions is to use the hydrolytic action of water under equilibrium condi tions to relieve thermally induced stresses across the interface. If equilib rium conditions can be maintained, the two problems act to cancel each other out. Coupling agents are defined primarily as materials that improve the practical adhesive bond of polymer to mineral. This may involve an increase in true adhesion, but it may also involve improved wetting, rheology, and other handling properties. The coupling agent may also modify the inter phase region to strengthen the organic and inorganic boundary layers.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this research project is to evaluate and compare the effect of different surface treatments on surface properties. Also the effect of different surface treatments with silane coupling agents on the bond strengths between resin cement and four CAD/CAM lithium disilicate-based glass ceramics (LDGC). Materials and methods: This study had three levels of analyses. Part I: The physicochemical analyses of four CAD/CAM LDGC surfaces. The surface physicochemical compositions of the four LDGC products (e.max CAD, Vita Suprinity, Celtra Duo, n!ce) were analyzed using X-ray photoelectron spectroscopy (XPS). In addition, scanning electron microscopy (SEM) was used to analyze the microstructure of LDGC. Part II: The effect of different surface treatments on the micromorphology and the roughness of four CAD/CAM lithium disilicate- based glass ceramics Atomic force microscopy (AFM) was used to measure the surface roughness and scanning electron microscopy (SEM) was used to analyze the changes in the surface micromorphology. Part III: The effect of an experimental silane coupling agent (TEOS) with different surface treatments on bond strength of four CAD /CAM lithium disilicate-based glass-ceramics. The shear bond strength between the ceramic surface and resin cement was tested using shear bond testing after a 30 day storage in distilled water. Results: The chemical composition percentage on the nano surfaces of the LGGC changed after hydrofluoric acid treatment. Different surface treatments produced different values of roughness. The highest shear bond strength values were found with the use of hydrofluoric acid treatment and the combination of both hydrofluoric acid and sandblasting followed by manufacturer's recommendation of silane coupling application. Conclusion: Surface treatments and silane coupling agents play a significant role to obtain reliable bond strengths between resin cement and LDGC restorations.

They also exhibit excellent aesthetic outcomes, and life-like translucency. Moreover, glass ceramics can provide better adhesion to the underlying tooth preparation, compared with metal-bonded ceramics and oxide ceramics. This is achieved by application of HF etching and silanization, followed by bonding with resin cement. The resin cement is applied as the means to provide a seal, adhesion and 'filler' in the small space that exists between a restoration and prepared tooth. These unique properties have given rise to expanded restoration designs for glass ceramics in comparison to other ceramics, e.g., veneers, inlays or onlays. Hence, durable and stable adhesion is strongly required for the long-term success of these restorations. The aim of this project was to evaluate the durability of adhesion between CAD/CAM ceramics and resin cements as well as the effect of different factors on long-term ceramic adhesion. In the first experiment, two bonding models were compared and contrasted using a microtensile bond strength test. Two surface treatments and two resin cements were also examined. Ceramic to ceramic, as a bonding model, was found to be better than a ceramic to resin composite model. Surface treatments and resin cements had a significant effect on the microtensile bond strength. The second experiment aimed to evaluate the stability of long-term adhesion using six resin luting cements when bonded to three different CAD/CAM ceramics in water over 12 months. According to the outcomes of this study, VITA Suprinity(R) and VITA Enamic(R) demonstrated better long-term adhesion compared to IPS e.max(R) CAD. Furthermore, the microtensile bond strengths of ceramic and resin cement decreased up to 3 months but thereafter became relatively stable. Different resin cements showed different bonding behaviour during prolonged storage time. The third study examined the effect of two etching times on long-term ceramic adhesion and the effect of six resin luting cements on durability of adhesion. This study indicated that prolonged etching time could increase the microtensile bond strength of glass ceramics in the short-term, however, different etching times did not have an obvious influence on the long-term adhesion. In the fourth experiment, an evaluation of sorption, solubility and dimensional change of six resin luting cements immersed in various storage media was undertaken. Significant differences were observed in the sorption, solubility and dimensional change of the cements when exposed to the different storage media over time. The objective of the last experiment was to evaluate the effect of immersion time and media on fracture toughness of six resin cements. It was concluded that fracture toughness varied among the cements and the value decreased over time. Furthermore, the three storage media evaluated in this study seemed to not have had a significant effect on the fracture toughness. It was concluded that, in general, lower sorption, solubility and dimensional change in resin cements seems to produce a higher fracture toughness and microtensile bond strength to glass ceramics.
