The connection arrangement between an implant (1) and a straight or angled abutment (800) can be produced using a clamping screw (400) and an expanding ring (500). An inlet (830) is provided in the abutment (800), and near the lower end of the abutment (800) this inlet (830) is widened via a radially encircling groove (835). The expanding ring (500) through which the clamping screw (400) passes is supported in the groove (835), the head (410) of the clamping screw (400) pressing on the expanding ring (500), and its threaded segment (430) engaging in the threaded bore (21) of the implant (1). The clamping screw (400) can be pushed from below into the inlet (830), with the expanding ring (500) pushed on and with the head (410) leading. The implant (1) can have a non-rotationally symmetrical receiving contour on the inner cone, primarily an inner polygon, and the abutment (800) advantageously has a counter-contour complementary to the receiving contour. A special screwdriver is used for screwing.

[ We claim:] [1.] In combination:an implant having a head portion, a shaft portion depending from said head portion, and a bore extending through said head and shaft portions, said bore including an unthreaded section extending through said head portion and an internally threaded section extending through said shaft portion;an abutment having a neck portion extending outwardly from said bore of said implant and a root portion depending from said neck portion and extending axially into said bore of said implant, said root portion having an axially extending inlet in an end thereof remote from said neck portion and a radially extending groove encircling said inlet and communicating therewith; andconnecting means for connecting said abutment to said implant, said connecting means including a clamping screw having a screw head positioned in said inlet of said abutment and an externally threaded segment threadedly engaging said internally threaded section of said bore of said implant, an expanding ring positioned and maintained in said groove of said abutment by said clamping screw, which extends through said ring, and access means, located in said abutment and communicating with said inlet thereof, for permitting access to said screw head by a tool adapted to rotate said clamping screw and thereby thread said externally threaded segment thereof into said internally threaded section of said bore of said implant.
