Abstract: A method for securing a spacer to an implant integrated in bone. A spacer and a screw are engaged with a holder in a rotationally fixed position with respect to the holder. The spacer is engaged in a spacer engaging portion of the holder and the screw is engaged in a screw engaging portion of the holder. The screw is inserted in a threaded receiving passage of the implant such that threads on the screw engage threads of the receiving passage.
