A threaded implant for screwing into jawbone and supporting a spacer element in the screwed-in position is provided. The implant includes a socket arrangement which can cooperate with a tool for screwing in the implant. The socket arrangement also secures the spacer element in an applied position. The socket arrangement includes two separate sockets, of which the first socket can cooperate with the tool and the second socket permits rotational locking of the spacer element.
