  • Publication number: 20090291414
    Abstract: A method for forming a dental implant includes drilling a pilot hole in the jaw bone of a subject and then threading an implant body into the pilot hole. The implant body includes a threaded portion integrally formed with a head portion having a polygonal recess. The implant body is threaded until the threaded portion reaches a predetermined seating depth. Next, an impression coping is mated with the polygonal recess of the implant body so that a portion of the impression coping is friction fit within the polygonal recess. After mating the impression coping with the implant body, an impression of the impression coping is formed. An implant analog is then mated with a portion of the impression coping without dissecting a portion of the impression tray. The implant analog is then used to form the dental implant.
