Available in PDF, EPUB and Kindle. Book excerpt: In dental practice, wear of the natural dentition is commonly seen in patients of all ages. It can have a mild effect on teeth, or be severe enough to affect patients' quality of life. Although different indirect restorative materials such as gold alloy or porcelain have been used for many years to restore excessively worn teeth, the procedures are generally complex and challenging to the dentists as well as costly and time-consuming for the patients. A good restorative material should be aesthetic, durable and not be abrasive to the opposing dentition. Gold has been reported to be "enamel-friendly", but the colour makes it un-aesthetic. On the contrary, porcelain is aesthetic, biocompatible, durable and has become a popular choice for both clinicians and patients. However, previous studies have shown that some of the porcelain systems can be abrasive to the opposing natural enamel. The use of such abrasive porcelain systems would therefore be harmful to a patient's dentition in the long term. Four porcelain systems and a gold alloy have been selected for this study: a veneering porcelain normally used in porcelain bonded to metal restorations (PBM-veneering porcelain); a leucite-reinforced glass ceramic used for veneering (LR-veneering ceramic); a leucite-reinforced pressable ceramic (LR-pressable ceramic); a machinable ceramic; a type III gold alloy (gold). The aims of the study were to determine the wear rates of the selected porcelains and opposing enamel under controlled conditions which simulated two clinical conditions: heavy attrition at near neutral pH (pH 6.1); heavy attrition with gastric regurgitation (pH 1.2). In addition, preliminary studies on the wear of zirconia and enamel were conducted. In this study, electro-mechanical tooth wear machines were used to simulate wear. Wear volume loss was measured by scanning specimens with 3D profilometers and evaluating the data using a purpose-written software. The surface micromorphology of wear facets was also observed by scanning electron microscopy (SEM). As a result of this analysis a more detailed investigation of the machinable ceramic was undertaken. The results revealed that at pH 6.1, while enamel wear caused by the PBM-veneering porcelain, LR-veneering ceramic, machinable ceramic and gold alloy were not significantly different to the control group in which enamel specimens were worn against each other, significantly increased enamel wear was associated with the LR-pressable. Although enamel wear rates increased dramatically in conditions simulating attrition combined with gastric regurgitation, the gold alloy did not wear the opposing enamel more than the enamel controls. In addition, in this study the machinable ceramic became porous under acidic conditions. The findings presented in this thesis have implications for selection of porcelain for specific clinical cases. Although the findings should be cautiously extrapolated to in vivo conditions, they contribute to the understanding of new porcelain materials in terms of wear and erosion. In addition, results from preliminary experiments with zirconia will provide data to inform the development of protocols for future research.

Available in PDF, EPUB and Kindle. Book excerpt: Much research has been carried out and a lot of progress has been made towards the use of composite materials in a wide field of tribological applications. In recent years studies have been made to determine to what degree phenomena governing the tribological performance of composites can be generalized and to consolidate interdisciplinary information for polymer-, metal- and ceramic matrix composites.The importance of promoting better knowledge in the areas of friction, lubrication and wear, in general, is demonstrated by the contents of this volume. It covers a wide range of subjects extending from fundamental research on the tribological characteristics of various multi-phase materials up to final applications of composites in wear loaded, technical components. Besides the emphasis on composites tribology, the great practical aspect of the field in many industrial applications is also reviewed by authors who are engaged in applied research as well as those in more academic activities. The articles in this volume will facilitate both researchers and mechanical designers in their work towards a set of predictive, materials engineering-related models for a more reliable use of composites as tribo-materials.Through the study of, and observation of, the tribology of sensibly formulated composite systems may emerge a clear and more profound understanding of the subject of tribology. In this sense, this book offers a major and critical evaluation of the state of understanding of the principles of tribology and its ability to serve the practical and commercial needs of this technology generally, and particularly in the context of composite systems.

Available in PDF, EPUB and Kindle. Book excerpt: Erosive tooth wear is a multifactorial condition of growing concern to the clinician and the subject of extensive research. Since the publication of the first edition of the book with the title Dental Erosion, new knowledge for a better understanding of this important subject has been gathered. The new and more detailed insights resulted in this second, extended publication. It presents a broad spectrum of views, from the molecular level to behavioural aspects, as well as trends in society. In particular, the issues concerning chemical and biological factors as well as dental erosion in children are covered more extensively in this second edition. The first chapters include topics such as the definition, diagnosis, interaction, epidemiology and histopathology of tooth wear. Further, the aetiology of dental erosion, including nutritional and patient-related factors, and dental erosion in children are discussed. This book is a valuable and indispensable guide to better oral health and is highly recommended to faculty members, researchers, dental students, practitioners and other dental professionals.
Download or read book Dental Composite Materials for Direct Restorations written by Vesna Miletic and published by Springer. This book was released on 2017-11-25 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers both basic scientific and clinically relevant aspects of dental composite materials with a view to meeting the needs of researchers and practitioners. Following an introduction on their development, the composition of contemporary composites is analyzed. A chapter on polymerization explains the setting reactions and light sources available for light-cured composites. The quality of monomer-to-polymer conversion is a key factor for material properties. Polymerization shrinkage along with the associated stress remains among the most challenging issues regarding composite restorations. A new classification of dental composites is proposed to offer more clinically relevant ways of differentiating between commercially available materials. A review of specific types of composites provides an insight into their key issues. The potential biological issues of dental composites are reviewed in chapters on elution of leachable substances and cariogenicity of resin monomers. Clinical sections focus on material placement, finishing procedures, and the esthetics and clinical longevity of composite restorations. Bonding to tooth tissues is addressed in a separate chapter, as is the efficiency of various composite repair methods. The final chapter discusses future perspectives on dental composite materials.

This book was released on 2023-01-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background With an increase in aesthetic demands, the use of all ceramic materials for fixed prosthesis have become the new normal. There are few limitations like wear of the restoration, fractures of the ceramic veneer, colour stability with all ceramics when compared with the gold standard metal ceramic restorations. With the advancements in CAD-CAM technology, various newer materials like PEEK (Polyetheretherketone) are being introduced in the field of dentistry which can be used as alternatives to all ceramics. Aim To compare and evaluate the wear resistance, antagonist wear, colour stability and displacement resistance of zirconia layered with ceramic and PEEK layered with indirect composite fixed dental prosthesis. Material and Methods The study evaluated the wear resistance, abrasiveness, colour stability and displacement resistance of the PEEK layered with indirect composite FDPs and Zirconia layered with indirect composite FDPs using a chewing simulator with aging, a Digital Spectrophotometer and a universal testing machine respectively. A independent sample "t" test was the statistical analysis performed using IBM SPSS Version 20.
