Although prosthodontics has been practiced for several thousand years, the science of dentistry and dental care have made their greatest advances over the past 100+ years. What started out with the ground‐breaking work of Greene Vardiman Black (1836–1915), reached its cur- rent extraordinary achievements and capabilities with a variety of innovations in the basic sciences, biomaterials science, radiography, dental armamentaria. . . and the dental implant. The modern dental implant is based on the pioneering work of the Swedish orthopedic surgeon, Per‐Ingvar Brånemark, in 1952. Basically, a dental implant is a surgical fixture placed into the jawbone where it fuses with bone or osseointegrates over the span of a few months. Thus, the dental implant becomes a replacement for the root of a missing tooth such that it can support a replacement tooth or bridge. In fact, dental implants are now considered the standard of care for most prosthetic replacements of missing teeth. The great advantage of an osseointegrated dental implant is that it is remarkably stable, mimics a natural tooth and will function independently of adjacent teeth. The success rate for dental implantology is now close to 98%, making dental implants the most successful of any restorative dental treatment. This book was written in response to numerous requests to make available a practical guide to dental implants that functions as a virtual “how‐to” manual for the dentist. What we have tried to do is discuss the many different aspects of dental implantology, even that difficult subject of economics, and give examples of each treatment modality covered in the text. We have also provided literature references so that the interested reader can delve more deeply into any subject that catches their interest. vii viii Preface We hope we have succeeded in our efforts and that this book will prove to be a useful guide and help to dentists as they embark upon the exciting task of placing and restoring dental implants for their patients.
