A dental implant includes a spiral thread for threaded engagement with a passageway formed in bone or tooth to mechanically secure the implant. A hollow stem extends upwardly to provide a passageway to a plurality of outlets at the lower end to fill a mold from the bottom up to develop an abutment ultimately supporting a crown, bridgework, or other prosthetic. The stem includes an end for engagement by a conventional dental hand piece to rotatably insert the implant. The base of the stem may include a hexagonal nut or a double disc for engagement by a dental ratchet for final seating of the implant. The post of the implant may include one or more longitudinally aligned tips that can be cut off to conform the length of the post with the depth of bone or tooth into which it will become inserted. The stem may include one or more longitudinally aligned segments that may be severed to conform the length of the stem with the height of the crown, bridgework or prosthetic. In a variant implant, the post includes a further passageway extending from the passageway in the stem to permit injection of bonding material into the further passageway for discharge through outlets of the further passageway into annular grooves formed in the one about the cavity into which the post is inserted.
