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.

This book was released on 2008-04-15 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aesthetic dentistry has become increasingly important to dentists and their patients. This book is designed as a springboard to assist clinicians in developing the aesthetic potential of restorative procedures. The book marries evidence-based principles with handy hints and tips the author has distilled from years of clinical experience. This combination of scientific principles with ‘real world’ practice will boost the confidence of budding aesthetic practitioners and clinical dental students. The book focuses on the principles of aesthetic work across the dentist's repertoire, rather than concentrating on one particular technique. For this reason, it will add value to the range of daily restorative work in the dental surgery.

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 2016 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: All-ceramic restorations have excellent esthetic outcomes compared with other restorative materials. Lithium disilicate is classified as one of many silica-based all-ceramic materials. Currently, companies have provided single-step adhesives, known as universal adhesives, compatible with different restorative materials including lithium disilicate. Many studies have reported greater bond strengths when using a silane to treat the lithium disilicate before applying the bonding agent. Moreover, few studies were published comparing the bond strength when using the universal adhesive alone. Purpose: The objective of this study was to evaluate and compare shear bond strength of three universal adhesives to lithium disilicate ceramic restorative material. Materials and Methods: Three universal adhesive bonding agents were selected from commercially available adhesives. 408 IPS e.max CAD ceramic discs were processed, fired, and etched for 20s. The specimens were divided into six groups. The first three groups used the universal adhesive directly. The remaining three groups were treated with silane. Then, a composite resin cylinder was placed on top of the adhesive using a bonding jig. Each group was subdivided into four equal subgroups (n = 17), subjected to different aging simulation procedures: 24 h, one month with 5000 thermocycles, two months with 5000 cycles, and three months with 5000 cycles. Then, specimens were debonded using shear force by a universal testing machine (MTS). Results: Shear bond strength was greater with silane than without silane (p

Abstract: Abstract 1 ABSTRACT Purpose: To investigate effects of metal thicknesses and surface treatment methods on the shear bond strength of a dual cured composite resin bonded to three different ceramo-metal dental alloys: nickel-chromium, high-gold and high-palladium dental alloys. Materials and Methods: A dual-cured adhesive composite resin was used to bond dental metal alloy plates of different thickness, composition and surface treatment to acid etched bovine enamel. The specimens (n=180) were stored in water for 24 hours and then loaded in shear with a universal testing machine to failure and bond strengths were recorded. Results: Using ANOVA, the mean shear bond strength for nickel chromium was found to be significantly higher than the other two noble metals (P0.05). Heat treatment of the noble metals showed no significant difference in bond strength compared with sandblasted samples (P>0.05). There was a significant increase in mean shear bond strength with increase in metal 1 Abstract thickness from 0.5mm to 0.7mm (PConclusion: Within the limitations of this study, resin-bonded metal alloy restorations with thickness of 0.7mm or more are preferred over 0.5mm thickness. The differences in shear bond strength between the two noble alloys and the nickel chromium alloy is likely due to the lack of suitable metal oxide. Heat treatment of precious metal alloys did not increase the bond strength to etched enamel and therefore further studies should investigate the use of copper containing gold and non-gold noble alloys which are thought to create suitable oxides for bonding. The relationship between composition of metal alloy, method of surface treatment and the choice of adhesive primer should be carefully considered before clinical use.
