The introduction of dental implants to the world of dentistry has successfully added to the restorative options for treating both completely and partially edentate patients, thereby restoring their masticatory ability and esthetics. Implant dentistry evolved over about five decades and along with it evolved the restorative techniques and components. However, there is a lack of an in-depth review of the implant abutments-the classification, types and the clinical application of each specific type. This book, thus, aims to aid the clinician in abutment selection procedure by reviewing and revisiting this critical component with regards to its connection with the implant, the type of material, retentive mechanism for the prosthesis and its fabrication method.
