THE INVENTION
The Appellant claims a dental implant. Claim 48 is illustrative:
48. A dental implant adapted to be at least partially implanted within an
upper or lower portion of a jawbone, said dental implant comprising:
an apical insert adapted to be at least partially inserted in a jawbone,
said apical insert including an upper portion and a lower portion each having
ends, said lower portion including an outer surface adapted to engage the
jawbone, said upper portion including a connection cavity that extends along
a longitudinal axis of said apical insert, said connection cavity including a
connection surface, said upper end of said upper portion having an opening
that provides access to said connection cavity, said apical insert including a
plurality of engagement surfaces positioned between said ends of said upper
and lower portions;
a coronal base adapted to be at least partially inserted in the jawbone
when connected to said apical insert that has been at least partially inserted
in the jawbone, said coronal base including a body having a longitudinal
axis, said body including an upper engagement surface, a distal end and an
internal passageway extending along said longitudinal axis of said body and
between said upper engagement surface and the distal end, said distal end
and said upper engagement surface each including an opening into said
internal passageway, said opening in said distal end adapted to telescopically
receive at least a portion of said upper portion of said apical insert, said
internal passageway including a plurality of engagement regions adapted to
engage a plurality of said engagement surfaces on said apical insert when
said coronal base is inserted on said apical insert, said plurality of said
engagement surfaces on said apical insert and said plurality of engagement
regions on said coronal base enabling said coronal base to be at least
partially locked in a plurality of different positions about said longitudinal
axis of said apical insert, said internal passageway of said coronal base at
least substantially aligned with said connection cavity of said apical insert
along said longitudinal axis of said coronal base and apical insert when said
coronal base is inserted on said apical insert;
an engagement abutment having an upper and lower section and an
internal passageway extending along a longitudinal axis of said engagement
