Modern tendencies of dental implantation are aimed at minimizing surgical trauma and reducing the time for rehabilitation of patients. In this connection, new implant technologies without bone plastic are becoming widespread, which allow to reduce the volume and quantity of surgical interventions and shorten the time of treatment.As well different alternative methods have been proposed, such as implants placed in specific anatomical areas like the pterygoid region, the tuber or the zygoma. Any of these procedures requires considerable surgical expertise and has its own advantages, limits, surgical risks and complications involving biological and financial costs. Aim of this book is to present Alternative Implantologic Decisions for Rehabilitation of Patients with Edentulism and Severly Atrophic Maxilla. The work is interesting, and useful to the clinicians.
