This book was released on 2013 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of ceramic restorations depends upon factors like the composite resin cement, the adhesive, cementation procedure and the substrate. With the introduction of newer ceramic and adhesive systems the factors that contribute to the most durable bond strength remains unclear. The objective of the study was to measure 24 hour and thermocycled shear bond strength of a composite to lithium disilicate glass ceramic with a universal single bottle adhesive. A combination of surface treatments of hydrofluoric acid, silane, salivary contamination and subsequent cleaning were also evaluated. Blocks of lithium disilicate (e.max CAD) were sectioned, polished with a rotational polishing device using a series of SiC disks and finished with 0.5[mu] Al2O3 slurry. All specimens were cleaned in an ultrasonic cleaner and were examined to ensure uniform surface finish. Surface treatments were done with concentrations of hydrofluoric acid and silane in various combinations followed by a bonding agent, according to the manufacturer's protocols. A cylinder of composite of diameter (1.5mm) was bonded to the cured adhesive and specimens were stored for 24 hours. In the next part of the study; saliva, collected from a single participant (2hrs postprandial), was pipetted onto the etched and silanated surfaces. Additionally some surfaces were cleaned using reagent alcohol or 35% phosphoric acid and the bonding agent applied, cured and composite cylinders bonded. For both the studies, the specimens were tested at 24 hours after bonding and the second group thermocycled for 10,000 cycles (5-50°C/15 sec dwell time) and debonded. For debonding the specimens were subjected to shear loading until failure using a universal testing machine and the shear bond strength calculated from the peak failure load. Contact angle measurements and scanning electron microscopy were used to analyze the effects of the treatments on the specimen surfaces. Data were analyzed with ANOVA and Tukey/Kramer post-hoc tests (p=0.005). Data were presented as estimated marginal means (least-square means).

Book excerpt: Bonding to Ceramics provides students, researchers and clinicians with detailed knowledge of ceramic structures, adhesion mechanisms, quality research design, material selection and clinical performance of dental ceramics. Based on collaborative research efforts and evidence-based clinical data, this book describes the basic properties of ceramics and the applications, failures and limitations of this material. The book features 500 clinical images, many of them in 3D, to aid the understanding of: ceramic microstructures; the basic principles and properties of ceramics; clinical applications and causes of failure. It also discusses the development of experiments to test ceramic designs, how to select the appropriate material according to the specific clinical application, as well as evidence regarding adhesive mechanisms for bonding ceramic restorations. Through examining clinical failures, the book also aims to improve clinical performance through the suggestion of improved materials, structures and designs. The ultimate aim of this book therefore is to provide the reader with the knowledge to be able to select the appropriate ceramic material and bonding technique for each clinical application.

Download or read book Introduction to Glass Science and Technology written by James E Shelby and published by Royal Society of Chemistry. This book was released on 2015-11-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise and inexpensive introduction for an undergraduate course in glass science and technology. The level of the book has deliberately been maintained at the introductory level to avoid confusion of the student by inclusion of more advanced material, and is unique in that its text is limited to the amount suitable for a one term course for students in materials science, ceramics or inorganic chemistry. The contents cover the fundamental topics of importance in glass science and technology, including glass formation, crystallization, phase separation and structure of glasses. Additional chapters discuss the most important properties of glasses, including discussion of physical, optical, electrical, chemical and mechanical properties. A final chapter provides an introduction to a number of methods used to form technical glasses, including glass sheet, bottles, insulation fibre, optical fibres and other common commercial products. In addition, the book contains discussion of the effects of phase separation and crystallization on the properties of glasses, which is neglected in other texts. Although intended primarily as a textbook, Introduction to Glass Science and Technology will also be invaluable to the engineer or scientist who desires more knowledge regarding the formation, properties and production of glass.

Download or read book Silane Coupling Agents written by Edwin P. Plueddemann and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 238 pages. 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.

Download or read book Esthetic Oral Rehabilitation with Veneers written by Richard D. Trushkowsky and published by Springer Nature. This book was released on 2020-04-16 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book acquaints the clinician with the full range of parameters that need to be considered before undertaking an esthetic rehabilitation with veneers and describes current clinical concepts and techniques. The initial chapters provide the foundation for a comprehensive treatment plan. It is explained how digital smile design in conjunction with a wax-up and functional esthetic prototype allow a patient to visualize the possibilities. Occlusion prior to the initiation of treatment and following treatment is key to the longevity of restorations, and this aspect is given careful consideration. Detailed advice is also offered on proper selection of materials and their placement. The guidance provided will ensure that the reader is fully equipped to gather and assess all relevant information prior to commencement of the final treatment. The treatment itself can range from minimally invasive to more complex depending on the requirements of each individual case. Among the clinical concepts discussed in the book are the use of etched porcelain restorations, minimally invasive CAD/CAM veneers, and the ink glue technique.
