Applied Dental Materials 9th Edition PDF Free Download
In producing this ninth edition of Applied Dental Materials we have updated the text in both content and appearance. We hope that the book will remain helpful to students and teachers of the science of dental materials alike by remaining true to the core principles and developing them into a more comprehensive text which covers a wide spectrum of materials falling within the scope of ‘dental materials’. Hence, there are more references to practical issues like handling and clinical performance of materials, whilst maintaining a strong link to quality issues encompassed within newly developed ISO standards. Some areas, such as adhesion, ceramics, light activation technology, CAD-CAM have been developed and expanded signifi cantly from the eighth edition, refl ecting signifi cant changes or developments in these areas. There is a new chapter on endodontic materials. All areas have benefi ted from a fresh approach to the use of drawings and photographs including the use of colour for the fi rst time.
The science of dental materials involves a study of the composition and properties of materials and the way in which they interact with the environment in which they are placed. The selection of materials for any given application can thus be undertaken with confi dence and sound judgement. The dentist spends much of his professional career handling materials and the success or failure of many forms of treatment depends upon the correct selection of materials possessing adequate properties, combined with careful manipulation. It is no exaggeration to state that the dentist and dental technician have a wider variety of materials at their disposal than any other profession. Rigid polymers, elastomers, metals, alloys, ceramics, inorganic salts and composite materials are all commonly encountered. Some examples are given in Fig. 1.1 along with some of their uses in dentistry. This classifi cation of materials embodies an enormous variation in material properties from hard, rigid materials at one extreme to soft, fl exible products at the other. Many dental materials are fi xed permanently into the patient’s mouth or are removed only intermittently for cleaning. Such materials have to withstand the effects of a most hazardous environment. Temperature variations, wide variations in acidity or alkalinity and high stresses all have an effect on the durability of materials.
