An abutment analog for fabricating an implant-based dental restoration includes an abutment base which is fixed within a patient's mouth in an angularly indexed fashion. After an impression is made, an implant analog will be attached to the abutment analog, and the combined abutment analog and implant analog will be replaced within the impression. The resulting impression, including the abutment analog and attached implant analog, will be used to make a model of a patient's mouth structure, to permit fabrication of a dental restoration device in a laboratory.
