Patent ID: 7806685

Claim:
A dental implant system comprising: a base member that is adapted to be embedded within a patient's jawbone at a treatment site, wherein the base member has a generally flat top side, a generally flat bottom side, and a central opening that is geometrically centrally located within the base member, wherein the central opening tapers inward with a constant taper from the top surface to the bottom surface, wherein the top side further includes at least one matable feature that is configured to mate with a corresponding feature on a crown to ensure non-rotatable alignment of the crown with the base member, and wherein the base member has an outer periphery that tapers with a straight taper inward from the top surface to the bottom surface such that the top surface is greater in surface area than the bottom surface; an implant screw comprising a head and a threaded end, wherein the threaded end is adapted to pass through the central opening of the base member and into the patient's jawbone, and wherein the head has a tapered section that is adapted to be seated within the tapered opening of the base member after the threaded end is screwed into the patient's jawbone, with the implant screw securing the base member to the jawbone while the base member is embedded within the patient's jawbone, wherein the head of the implant screw includes a threaded hole in the head that extends downward through the tapered section; and a crown that is adapted to be mounted to the head of the implant screw via a screw that passes into the threaded hole in the head of the implant screw, wherein the crown includes a corresponding matable feature that mates with the base member, wherein the matable feature of the base member comprises a projection adjacent the outer periphery that projects upward from the top side of the base member a distance that is below the head of the implant screw, and wherein the matable feature of the crown comprises a recess on a bottom end of the crown.
