A dental implant for coupling an artificial tooth to a jawbone of a patient is provided. The dental implant includes an elongated body having a first end threaded bone-engaging portion for engaging the dental implant with the jawbone and a second end, and wherein the dental implant is adapted to operate as a conduit for bone grafting material by enabling introduction of the bone grafting material into a grafting space extending between said elongated body and the patient's jawbone surrounding it. Preferably, the dental implant includes a plurality of longitudinal grooves located at the external surface of the threaded bone-engaging portion of the dental implant, or includes circumferentially located openings, to allow delivery of bone grafting material into the grafting space.
