1. A full anatomy model (FAM) for image-guided dental implant treatment planning, which at least contains the anatomy components of bones and soft tissues, may contain teeth and nerves if applicable, may contain any other anatomical or artificial structures, represents multiple anatomical components in one or more geometric models using any geometric representation, but preferably, triangulated models, is created from the data acquired for implant treatment planning including the patient 3D scan (such as CT and Cone-beam CT), radiographic guide CT or optical scan, optical scans of conventional physical dental models, optical scans of impressions, or intra-oral scan of patients, registers all component models into one coordinate system, preferably, that of the patient 3D scan, and may or may not assemble all the individual components into one geometric assembly.
