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 means for coupling the abutment to the implant anchor.

Claims

1. (canceled)

2. A fastener for embedment in bone, formed by:

fashioning a thread pattern which is chevron shaped in section by first, cutting a radial superior surface (35) at an angle beta on a blank and then another radial superior surface (34) inboard surface (35) at an angle alpha such that collectively the two superior surfaces form a “

V”

,

cutting a flank surface (36) underlying surface (34) at an angle gamma, and

cutting a relief surface (38) underlying surface (35) such that surfaces (36) and (38) form a “

V”

.
