Claim:
A dental implant for coupling an artificial tooth to a jawbone of a patient which comprises an elongated body having a first end threaded bone-engaging portion for engaging the dental implant with said jawbone and a second end, wherein the dental implant is configured to operate as a conduit for bone grafting material, said dental implant comprising one or more longitudinal grooves located at an external surface of said threaded bone-engaging portion of the dental implant which extend from the second end of said dental implant to the first end thereof, to enable the conveying of said bone grafting material along said one or more of the longitudinal grooves towards a grafting space extending between said elongated body and the patient's jawbone surrounding it, wherein said dental implant further comprises a skirt shaped semi-permeable membrane, made of collagen and attached to the elongated body so as to at least partially cover a coronal part of the threaded end, and adapted to be positioned either in a first upwardly raised position or in a second downwardly spread position, wherein the latter position is adapted to provide a cover for the grafting space.
