ABSTRACT:
A self-tapping dental prosthetic implant has a blunt leading end, a tapered first section which has a uniform minor diameter and a uniformly increasing major diameter, a second section having uniform minor and major thread diameters, a third section with a uniform major thread diameter and a outwardly tapering minor diameter and a fourth section which has a diameter larger than any other segment and a relatively low profile (i.e., short axial length). A thread-cutting groove extends over a substantial portion of the threaded length of the implant. A stepped drill with a tip having a large included angle is used to drill a pilot hole permitting anchoring in the proximate and distal portions of cortical bone by the threaded implant.
