Abstract: A dental implant device for insertion into a bore defined in bone for use with a prosthetic tooth or dental appliance includes an abutment with a plurality of male keys disposed about the distal end of the abutment capable of being affixed to the prosthetic tooth or dental appliance, an implantable anchor having a proximal and distal end, a plurality of female keyways defined into the proximal end of the anchor, the keyways capable of coupling to the male keys of the abutment and thereby preventing relative rotation of the abutment and anchor; an interlocking thread helically defined around a longitudinal axis of the anchor, the thread being adapted to couple to the bore defined in the bone and elements for coupling the abutment to the implant anchor.

Abstract: The apparatus and method is directed to a pair of self-tapping, interconnecting, externally and internally threaded devices that, when installed between two separate pieces of material, will draw and hold the material together as a single threaded unit. While the pair of threaded devices are being fastened into the host material, due to the unique design of their threads, no radial outward forces are produced that could cause cracking or splitting of the sections of the material into which they are installed. The external threads are helically defined into the exterior of each half of the device with a right hand thread defined into one half and a left hand thread into the other half. When the two halves are being fastened together, the increased thread pitch on one of the halves continuously draws the halves into each other even when the internal threads have already been maximally tightened.
