ABSTRACT:
Abutment posts and copings for use with dental implants are disclosed. The abutment post has at one end means to affix it to the implant so as to extend supragingivally from the implant through the gum tissue. The post tapers down in cross-section from a region at or near the exposed surface of the gum tissue to its free end, and has at its free end a socket for receiving the coping. The coping has at its open end a hollow flaring section dimensioned to fit over and envelop the tapered post section, and a socket section at the smaller end of the flaring section which fits over and mates with the socket on the post. The flaring section of the coping extends to the locus of the boundary between the post and the exposed surface of the gum tissue, where the coping and the post can meet along that locus and form a seal, or provide rigidity to the installed restoration.
