Abstract: A submergible or non-submergible (“one stage”) screw-type implant for use in the immediate post-extraction site of a patient's tooth. In order to increase the ability of regenerated bone to anchor the implant, an upper portion of the implant has a preferably generally conical shape and has a plurality of spherical projections sintered to its outer surface to make it suitable for bone integration and retention. The lower portion of the implant has a cylindrical shape with threads extending over a portion thereof. A channel is located through the threads and is shaped so that one side forms a cutting edge that makes the lower portion of the implant self-tapping into the bone at the base of the tooth extension socket.
