Patent ID: 8485819

Claim:
A dental prosthesis, comprising: an implant having distal and proximal portions, the implant proximal portion including distal and proximal segments, the implant proximal segment having a tapered outer surface; an abutment having a distal portion, a proximal portion having a first end and an opposing second end disposed adjacent the distal portion of the abutment, the proximal portion having an external concave surface extending from the second end and configured such that the concave surface increases in diameter in an axial direction from the second end toward the first end, the second end being configured to circumferentially engage the outer surface of the implant proximal segment such that an abutment joint is defined therebetween, and an abutment cavity formed complementary to the outer surface of the implant proximal segment to facilitate circumferential engagement of the abutment to the outer surface of the implant proximal segment; and a crown configured to be positioned over the abutment and the implant such that the crown covers the implant abutment joint, wherein: the crown includes a crown distal portion defining a crown distal end having a crown cavity formed therein, and the crown cavity being configured complementary to at least a portion of the abutment proximal portion such that the crown distal end circumferentially engages the implant proximal segment.
