Abstract
Abstract Blade for endosseous implants for supporting dental protheses, having two pins for supporting dental protheses and six lengthened appendices, two of which being longer than the other ones, with shaped surfaces suitable to be fixed into an osseous groove for retaining the blade. The blade may be cut in order to assume a large number of different conformations which render it suitable for any implant in the jawbone or in the mandibular bone.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
Blade for osseous implants for supporting and retaining dental protheses, constituted of a biologically neutral metal material and comprising a lengthened cross-arm having two sets of shaped appendices protruding from one of its sides and two axially spaced pins from the other on which it is possible to mount said protheses, each of said pins and respectively one of said sets of appendices forming a structure identical to and being a mirror-image of the other pin and set of appendices, said cross-arm and appendices being of essentially flat coplanar configurations, each said set of appendices including an elongate main appendix extending coaxially with and opposite to respectively one of said pins and being located between a pair of elongate side appendices, a shaped cavity being formed at the free end of said main appendix, said side appendices being shorter than the main appendix and having the free ends thereof inclined toward said main appendix, adjacent side appendices of said two sets of appendices merging with each other in the region of said cross-arm whereby the blade is essentially symmetrical about an axis parallel to and intermediate the axes of said pins.

Claim 3
Dependent Claim
31 words
Blade for endosseous implants according to claim 1, characterized in that said two main appendices have a toothed profile and that at least a hole is made in said main appendices.
Claim 4
Dependent Claim
26 words
Blade for endosseous implants according to claim 1, characterized in that the profiles of said side appendices are shaped according to a plurality of successive undulations.
Claim 5
Dependent Claim
21 words
Blade for endosseous implants according to claim 3, characterized in that said successive undulations have essentially the shape of successive semicircles.
Claim 6
Dependent Claim
24 words
Blade for endosseous implants according to claim 2, characterized in that said toothed profiles of the main appendices define vertices turned towards said cross-arm.
Claim 7
Dependent Claim
21 words
Blade for endosseous implants according to claim 1, characterized in that the free ends of said pins are thickened and round.
