Abstract

A dental prosthesis comprises an implant, an abutment and a crown. The implant has distal and proximal portions with the implant proximal portion including distal and proximal segments. The implant proximal segment has an outer surface. The abutment has distal and proximal segments and defines an abutment shoulder therebetween. The abutment shoulder is configured to circumferentially engage the outer surface of the implant proximal segment such that an implant abutment joint is defined therebetween. The crown is configured to be positioned over the abutment and the implant such that the crown covers the implant abutment joint. The implant proximal segment has an annular concave cross-section such that the crown distal end has a rounded shape to reduce the potential for stress cracking of the crown.
