Implant dentistry has become a vital part of prosthodontics for partially and completely edentulous patients.An implant stimulates the bone and maintains its dimension in a manner similar to healthy natural teeth. They do not decay or require endodontic treatment. They are also less prone to fracture and resist periodontal like disease better than teeth.My book on Diagnosis and Treatment plannning in Implant Restorations discusses the various requirements for a successful diagnosis and treatment planning of implant restorations in general; the criteria for selection of the implant candidate; radiographic and anatomic considerations; bone considerations; implant treatment planning for the completely and partially edentulous patient; biomechanical considerations; and occlusal considerations for implant supported prosthesis.
