Prosthodontic restoration components
DCFirst Claim
1. Prosthodontic restoration components for a dental implant system wherein an object substituting for a natural root is surgically implanted in edentulous bone of the alveolar arches of the jaws, said object providing, in the vicinity of the boundary between said bone and the fleshy gum tissue that covers said arches and normally invests the necks of natural teeth, receiving means for receiving and supporting such components, said components being an abutment post and a substantially rigid coping, said abutment post having at a first end means to affix said post to said receiving means so as to extend supragingivally from said implanted object through said gum tissue, said post having a trans-tissue section adjacent said first end, said trans-tissue section extending from said first end a distance substantially the same as the thickness of said gum tissue around said post, and a supragingivally-extending section which tapers in cross-section from said trans-tissue section to a smaller cross-section at its second end, and a mount section extending supragingivally from said second end on a substantially uniform cross-section for receiving said coping, said coping having a hollow flaring section open at its wide end and dimensioned to fit over and envelope said supragingivally-extending post section and a socket section at the smaller end of said flaring section dimensioned to fit snugly over said mount section, said flaring section extending at the boundary of its wide end to the locus of the boundary between said trans-tissue section and said supragingivally-extending section when said socket section is fitted over said mount section, and means engageable between said mount section and said socket section to bring said coping and said post into sealing contact between said respective boundaries.

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.
