Abstract: A device for detaching a tooth root. The device comprises: a lead screw having a threaded point for screwing into the tooth root, and a threaded shaft; a pivoting member including a bore through which the lead screw passes, the lead screw being retractable through the bore by rotational engagement of a threaded member with the threaded shaft of the lead screw; and a platform for supporting the pivoting member such that the lead screw is able to pivot relative to the platform, The lead screw includes a locking surface for preventing rotation of the lead screw during rotational engagement of the threaded member with the threaded shaft.
