Available in PDF, EPUB and Kindle. Book excerpt: INTRODUCTION Esthetic dentistry can be defined as the art and science of dentistry, applied to create or enhance beauty of an individual within functional and physiological limits. Where as cosmetic dentistry is application of the principles of esthetics and certain illusionary principles, performed to signify or enhance beauty of an individual to suit the role he has to play in his day to day life or otherwise. Appearance is closely linked to social acceptance and professional success. No longer are people satisfied with just looking good, it must be coupled with a complete feeling of total well-being. Newer technologies are being harnessed for this purpose and advanced research is being undertaken. Thus, focus of dentistry in the present times is not only on prevention and treatment of disease but also on meeting the demands for better esthetics. Newer dental materials developed for esthetic enhancement are now chosen for their excellent mechanical as well as esthetic qualities. Esthetic dentistry is emerging as one of the most progressive and challenging branches of this field. Thus dentistry has evolved from a curative to a creative science in a very short span. The modern history of esthetic restorative materials was started with silicate cement, introduced by Fletcher in 1878, the principle anterior restorative material of those days. But, silicate cements were discouraged later on because of their poor strength, irritation to pulp tissue and brittleness. Even the nature of its setting and structure were but imperfectly understood. Self curing acrylic resin was introduced to the dental profession in the mid- 1950s. Initially used for the construction of denture bases, acrylic resin has also been used for many other purposes, including denture teeth, temporary restorations, intraoral splints and veneering agents for crowns and bridges. Since their introduction, acrylic based materials have continued to play a major role in restorative and prosthetic dentistry. But they too showed poor physical properties like high polymerization, shrinkage and coefficient of thermal expansion, irritation to pulp and dimensional instability. In attempt to improve their properties, and the potential for greater application of resins came about with the introduction of the bisphenol A and glycidyl methacrylate, or BIS-GMA, system by R Bowen in the early 1960s .

Download or read book Thermoplastic Elastomers written by Chapal Kumar Das and published by BoD – Books on Demand. This book was released on 2015-11-26 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermoplastic elastomers (TPEs), commonly known as thermoplastic rubbers, are a category of copolymers having thermoplastic and elastomeric characteristics. A TPE is a rubbery material with properties very close to those of conventional vulcanized rubber at normal conditions. It can be processed in a molten state even at elevated temperatures. TPEs show advantages typical of both rubbery materials and plastic materials. TPEs are a class of polymers bridging between the service properties of elastomers and the processing properties of thermoplastics. Nowadays, the best use of thermoplastics is in the field of biomedical applications, starting from artificial skin to many of the artificial human body parts. Apart from these, thermoplastic elastomers are being used for drug encapsulation purposes, and since they are biocompatible in many cases, their scope of applications has been broadened in the biotechnological field as well. The present book highlights many biological and biomedical applications of TPEs from which the broader area readers will benefit.

This book was released on 2013-02-04 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forschungsarbeit aus dem Jahr 2004 im Fachbereich Medizin - Zahnmedizin, University of Mosul (Dental college), Sprache: Deutsch, Abstract: This study was carried out to evaluate the colour property of two types of acrylic resin materials cured by microwave technique in comparison with that cured by conventional water bath technique. Two types of heat cured acrylic resin materials were selected: Quayle–Dental and Major–base types. Seventy–two samples (30×20×1.5 mm) were prepared and divided into four experimental groups: Quayle–Dental and Major–base groups were cured by microwave technique and the others Quayle–Dental and Major–base groups were cured by water–bath technique. The number of samples for each group was 18. The colour property for the samples was evaluated using computerized ultra-violet–visible spectrophotometer with acc-uracy up to 0.001 nm. The absorbed light was measured which is also termed the optical density. The results of this study showed that there were no significant differences in optical density for acrylic resin samples cured by microwave and water–bath techniques, and the acrylic resin with smaller particle size (Quayle–Dental) showed higher optical density (colour property) than that of larger particle size (Major–base). Key Words: Optical density, colour prop-erty, microwave technique.

This book was released on 2012-08 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: From almost the time dentistry achieved a professional status, there has been a constant search to obtain a denture base material of life like appearance, one that would not deteriorate in service. The introduction and use of acrylic resin as a denture base material since 1937 has revolutionized the dentistry in a big way. Since then no other material has been found that matches the appearance of the oral soft tissues with as great fidelity as acrylic resin. Heat cured acrylic resins are the most commonly used materials for denture base processing. It has fine esthetic properties, excellent color stability and can be used with a simple technique for the construction of dentures. Inspite of having all these advantages, dimensional inaccuracies have been a critical component in assessing in vivo performances of these materials. These changes have profound effect on Complete Denture Occlusion. Even minor changes can lead to severe discrepancies. Dimensional inaccuracies is still a major challenge for the Prosthodontist which need to be corrected for better results. The aim of this study is to search for such a Denture Base material which shows minimal inaccuracies.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook describes several current trends in the development of bioceramics and biocomposites for clinical use in the repair, remodelling, and regeneration of bone tissue. Comprehensive coverage of these materials allows fundamental aspects of the science and engineering to be seen in close relation to the clinical performance of dental and orthopaedic implants. Bioceramics and biocomposites appear to be the most dynamic area of materials development for both tissue engineering and implantable medical devices. Almost all medical specialties will continue to benefit from these developments, but especially dentistry and orthopaedics. In this Handbook, leading researchers describe the use of bionanomaterials to create new functionalities when interfaced with biological molecules or structures. Also described are technologies for bioceramics and biocomposites processing in order to fabricate medical devices for clinical use. Another important section of the book is dedicated to tissue regeneration with development of new matrices. A targeted or personalized treatment device reduces drug consumption and treatment expenses, resulting in benefits to the patient and cost reductions for public health systems. This authoritative reference on the state-of-the-art in the development and use of bioceramics and biocomposites can also serve as the basis of instructional course lectures for audiences ranging from advanced undergraduate students to post-graduates in materials science and engineering and biomedical engineering.
