This book was released on 2008-10-10 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and scientifically based overview of the biocompatibility of dental materials. Up-to-date concepts of biocompatibility assessment are presented, as well as information on almost all material groups used in daily dentistry practice. Furthermore, special topics of clinical relevance (e.g,, environmental and occupational hazards and the diagnosis of adverse effects) are covered. The book will: improve the reader’s ability to critically analyze information provided by manufacturers supply a better understanding of the biocompatibility of single material groups, which will help the reader choose the most appropriate materials for any given patient and thus prevent adverse effects from developing provide insights on how to conduct objective, matter-of-fact discussions with patients about the materials to be used in dental procedures advise readers, through the use of well-documented concepts, on how to treat patients who claim adverse effects from dental materials feature clinical photographs that will serve as a reference when analyzing clinical symptoms, such as oral mucosa reactions.

Available in PDF, EPUB and Kindle. Book excerpt: For several years now scientific and medical sLaff have recognised the risks of toxicity of certain metals contained in alloys used in Lhe manufacture of biomaterials protheses, implants, and artificial organs. A number or scientific and industrial research centres have focussed their investigations in this direction and international societies and commissions have organised meetings with specialists from complementary disciplines in attendance in attempts to guage the importance of biological risks and to determine the toxicity of certain metals, with the aim of establishing preventive measures and guidelines. In the last century great efforts have been made to reduce unwanted biological effects caused by orthopaedic implants. The problems of pain and infection were overcome and the development of modern technology has resulted in a convincing decrease in corrosion problems and mechanical failure, such that ostosynthesis and endoprosthesis have rapidly progressed beyond the level of tentative investingation.llowever, a number of problems still remain to be solved, such as the influence of the material type on the healing process and its relative speed. The increasing use of cobalt-,chromium-and nickel-containing alloys in surgical and dental implants has raised various questions concerning the biological consequences of chronic internal release of these elements in the human body. A total of 55 delegates representing 16 countries heard presentations of fundamental aspects, local and remote tissue response, immunopathology, clinical aspects, and manufacturing qual ity control issues.
Download or read book Superalloys written by Mahmood Aliofkhazraei and published by BoD – Books on Demand. This book was released on 2015-11-25 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation. The crystal structure is typically face-centered cubic austenitic. Superalloy development has relied heavily on both chemical and process innovations. Superalloys develop high temperature strength through solid solution strengthening. An important strengthening mechanism is precipitation strengthening which forms secondary phase precipitates such as gamma prime and carbides. Oxidation or corrosion resistance is provided by elements such as aluminium and chromium. This book collects new developments about superalloys.

Download or read book Recasting of Nickel Chromium Alloy written by Jayant Palaskar and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recasting of dental casting alloy is of great advantage both economically and environmentally. Properties such as castability, hardness and porosity are of prime importance and must be considered in selection of an alloy for cast dental restorations. As per the review of literature there are very few studies on recasting of dental casting alloy. This study was designed to find out effect of recasting on castability, hardness and porosities. Castability was studied as complete casting of any metal restoration is mandatory and it can be know by castability test. Whitlock s castability test was implemented in this study. Ideally hardness should be high to resist any scratches and to maintain the smoothness of cast restorations during laboratory procedures and also in the oral environment. It denotes strength, stiffness, brittleness, resilience and toughness or combination of any of these qualities. Porosities in dental casting alloy can alter physical and mechanical properties of the metal which may lead to failure of crown and bridge and also cast partial denture prosthesis. Porosities were evaluated using a scanning electron microscope in this study.
