A method comprises attaching an abutment to an implant body so as to form a seal and cover the implant body, the implant body having a top portion with an external tapered surface and a bottom portion secured within a jaw bone of a patient. The abutment has a top portion adapted to secure a prosthetic component and a bottom portion adapted to be positioned below a gumline of the patient. The bottom portion of the abutment is shaped to attach to and fit over the implant body. The bottom portion of the abutment has a cavity with an internal tapered surface. The internal tapered surface of the abutment and the external tapered surface of the implant body form a Morse taper.
