ABSTRACT:
An endodontic implant comprises a smooth, non-threaded partially tapered shank having an integral crown portion on which an artificial tooth crown or denture is supported. The shank is implanted in the root canal of a tooth stump and through its apex into the jawbone of a patient. The shank is preferably provided with two tapered sections with an intermediate section of constant diameter and is dimensioned so as to occupy the whole of a root canal cavity when implanted therein. Preferably the implants are used in pairs, rigidly connected by a bar device to which a denture can be removably attached. The system anchors mobile teeth and prevents root resorption caused by instability.
