La discipline du g nie biom dical, qui applique les principes de l'ing nierie aux syst mes vivants, a ouvert une nouvelle re dans le diagnostic, la planification des traitements et la r adaptation des patients. L'un des aspects de ce domaine, la biom canique, comprend toutes sortes d'interactions entre les tissus et les organes du corps et les forces qui agissent sur eux. Les progr s dans la conception de proth ses, d'implants et d'instruments ont t r alis s gr ce la th orie et la pratique de l'optimisation de la conception m canique. Dans de nombreux cas, la biom canique peut litt ralement faire (ou) d faire un cas d'implant. Habituellement, dans toute structure soumise des charges fonctionnelles, il peut y avoir des situations conduisant une surcharge et des complications ult rieures. La biom canique est essentielle dans la conception des implants dentaires. L'objectif de ce livre est de r sumer les connaissances sur la biom canique des implants dentaires pour aider le clinicien faire face aux questions suivantes: Pourquoi existe-t-il autant de biomat riaux et de formes d'implants diff rents ? Les implants doivent-ils avoir des rev tements sp ciaux la surface et, si oui, pourquoi ? Un implant doit-il avoir une sorte d'amortisseur de chocs int gr ? L'objectif est de donner au clinicien une perception du processus de conception et des aspects biom caniques de la conception des implants.

The discipline of biomedical engineering, which applies engineering principles to living system, has unfolded a new era in diagnosis, treatment planning and rehabilitation in patient care. One aspect of this field, biomechanics comprises of all kinds of interactions between tissues and organs of the body and the forces acting on them. Advancements in prosthetic, implant, and instrumentation design have been realized because of mechanical design optimization theory and practice. In many instances biomechanics can literally make (or) break an implant case. Usually, in any structure subjected to functional loads, there may be situations leading to overload and subsequent complications. Biomechanics is critical in dental implant design. The objective of this book is to summarize knowledge about the biomechanics of dental implants to help a clinician confront the following questions: Why are there so many different implant biomaterials and shapes? Should implants have special coatings on the surface, and if so why? Should an implant have some sort of built-in shock absorber? The goal is to give the clinician perception into the design process and biomechanical aspects of implant design.

The gnathologic concept is useful in restoring teeth as well as eliminating occlusal problems. The mandibular movements can occur in either of the three planes; frontal, horizontal and sagittal. The movements in either of the planes are guided by the proprioceptive impulses. In dentulous patients, the impulses are obtained from the periodontal ligament whereas in edentulous patients, the impulses are generated from the temporomandibular joint. While mandibular movements cannot be reproduced with complete accuracy on an articulator, we should reproduce them with as much accuracy as possible to minimize damage to supporting structures from occlusal disharmony.This book aims at describing the importance of the maxilla-mandibular relations in maintaining the harmony of the stomatognathic system.
