Implant for attaching a substitute tooth or the like to a jaw

DETAILED DESCRIPTION These and other objects of the invention which shall be hereafter apparent are achieved by an implant provided with a threaded bore for fastening a substitute tooth or dentures at the jaw.
The implant comprises a carrier with at least two spikes for fastening the implant onto the jawbone and a diaphragm enabling bone formation and intended to cover the carrier.
In one preferred embodiment of the invention, the carrier has a central portion containing the threaded bore and a frame surrounding the central portion.
The frame comprises a base formed by transverse ribs and longitudinal ribs and at least four cross ties extending from the base edge.
Another preferred embodiment comprises a carrier with a thin base plate and a post.
The post projects upward from the base plate and is provided with a threaded base.
The diaphragm enables the consolidation of the implant with the bone tissues and can consist, for instance, of a porous polytetrafluoroethylene known under the trade name GORE-TEX or some other equivalent material.
The deposition of microorganisms in the region covered by the diaphragm, as well as the propagation of infection, can be inhibited by such a diaphragm.
The invention provides favorable conditions for the growth of new bone tissue in an intermediate space covered by the diaphragm, wherein the deposition of bone material at the implant and its solid anchoring thereon is promoted as well as accelerated.
