Claim 1

In a bone implant for securing artificial teeth to a jaw bone, comprising a substantially flat body plate having an outer end and an inner end and two broadsides, each of which is formed with transversely spaced apart, elongated depressions, which are transverse to the direction from said outer end to said inner end, the improvement comprising said depressions defined by softly curved corrugations merging into adjoining portions of said broadsides without forming a sharp edge therewith and being free of undercut surfaces, so as to facilitate removal of the implant without tearing off body tissue and while retaining existing friction between the jaw bone and the implant, the corrugations formed in one of said two broadsides being staggered from those formed in the other of said two broadsides, each of the corrugations having a longitudinal center plane and being symmetrical with respect to said longitudinal center plane, and the body plate being provided with a plurality of openings closed on all sides thereof, and being enlarged in thickness at said inner end thereof forming an arch-shaped blunt bead extending along the entire length of said inner end thereof, in order to promote the application of pressure by said inner end of the body plate to surrounding body tissue.
