Endodontic-prosthetic stabilization system

An endodontic implant for stabilizing a tooth which comprises a smooth non-threaded partially tapered shank having first and second ends, and a crown portion of circular cross-section integral with said first end of the shank, the shank comprising two tapered sections separated by a section of constant diameter, the first tapered section having a length of substantially 3 mm and tapering from the crown portion towards said constant diameter section and the second tapered section tapering from said constant diameter section towards said second end of the shank, the second tapered section having a length of substantially 16 mm and tapering constantly along its length such that its diameter where it meets said constant diameter section is substantially 0.3 mm greater than its diameter at said second end;

• the shank being adapted for implantation in a root canal of a tooth stump and being of a length such that the second tapered section passes through the apex of said root canal into the adjacent jawbone of a patient, whereby the tooth may be immobilized for supporting in a rigid manner an artificial tooth crown or a means for supporting a denture, the tapers of the implant shank being such that when implanted in the root canal of a tooth the whole of the root canal cavity is occupied by the shank.
