Abstract: Dental implants for supporting and positioning artificial teeth or prosthetic devices are provided. The dental implant is adapted to be installed and ultimately oseointegrated into a predrilled osteotomy site of either the maxilla or mandible. The dental implant has a generally cylindrical body with an apical threaded portion which is screwed and secured into the bone. The cylindrical body also includes an internal threaded bore extending from the second end into the cylindrical body along the longitudinal axis of the cylindrical body. An integral hexagonal shaped protrusion, when viewed along the bore of the cylinder, is preferably provided and extends from the end of the implant proximal the gingiva of the patient. The internal bore of the cylinder extends concentrically through both the annular base and the hexagonal protrusion.

Abstract: A dental implant for supporting and positioning an artificial tooth or other prosthetic device in the mouth, and preventing its rotation is provided. The dental implant is adapted to be installed in a pre-drilled bore in the bone of the maxilla or mandible and is eseointegrated into the bone. The dental implant has a generally cylindrical body with a first end implanted in the bone and second end including an annular base. The cylindrical body also includes a threaded bore extending from the second end into the cylindrical body along the longitudinal axis of the cylindrical body. A hexagonal shaped protrusion, when viewed along the bore of the cylinder, is integrally attached to and extends away from the annular base. The central bore of the cylinder extends concentrically through both the annular base and the hexagonal protrusion.
