ABSTRACT:
A prosthetic dental implant for anchoring to the mandible or maxilla for supporting artificial teeth and dentures includes a substantially flat yet slightly tapering endosteal blade portion constructed of a titanium alloy and including two columns of oblong slot-like apertures interior thereto and two edge columns of half-length oblong slot-like apertures. Support for an artificial tooth is provided by means of a support post which has a substantially circular lateral cross section throughout and an enlarged part-spherical lower portion and an upwardly and inwardly tapering portion thereabove. In an alternative arrangement, the vented concept provided by the slot-like apertures is replaced by a solid blade which includes a plurality of wedge-like lip portions outwardly extending from each side of the anchoring member and defining a recessed channel between adjacent lip portions, the lip portions and recessed channels on one side of the anchoring member being staggered from those on the opposite side.
