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.

The present invention relates to a novel combination device for tooth extraction with Snap-On handle and interchangeable or retractable working ends. More specifically, a four in one device for increasing movement of a tooth in the jaw. The invention is designed to create space between bone and root; elevate roots for easy extraction. The invention is a four in one interchangeable dental elevator extraction kit. The device provides a new and improved method of increasing movement and extraction of a tooth in a jaw. The novel dental tooth extraction device is composed of a single handle, single hollow metal cylinder with two double ended bits. One double ended bit contains two different straight elevators on opposite sides. The Second double ended bit contains two root tip picks on opposite ends. Each double bit is designed with a different tip.

An object of the present invention is to provide forceps for removing a dental implant fixture, in which pinching portions securely hold a fixture to remove the fixture implanted in an alveolar bone, and thus to prevent the pinching portions from slipping out of the fixture. Forceps for removing a dental implant fixture according to the exemplary embodiment of the present invention include: a pair of handles; coupling portions extended from the handles, crossed, and hingedly coupled; pinching portions connected to the coupling portions; and holding pieces protruding from ends of the pinching portions in a direction toward a center of a dental implant fixture and each having an arc corresponding to at least a part of an outer circumference of the fixture so that the holding pieces are inserted into a trough of a threaded portion formed on the outer circumference of the fixture.

In a method for controlling a device for the extraction in particular of a tooth root, the device has a front mouth-side support, a tensioning element guided in the latter, and a tensioning mechanism connectable to the tensioning element. The tensioning element is deflected, at the front, approximately at right angles to the longitudinal extent of the support and is connected to a pin fastenable in the tooth root. The tensioning element is drawn to its stretched state by a controllable motor with low expenditure of force or is connected in this stretched state to the pin. The tensile force is then increased manually or automatically to a predefined fixed or variable value by increasing output of the motor of the tensioning mechanism, and thereafter, when the tooth root has come loose, the motor output is reduced to a defined value or to zero.

An intraoral device for wiggling a loose tooth for easier extraction includes a distal portion configured to move in a back-and forth and/or twisting motion and including tooth contact portions configured to contact at least opposing sides of a loose tooth, a proximal portion including a drive for driving the distal portion, a form factor having aesthetics for engaging a child's mind, and a counter or timer configured to sense the number of cycles or duration of the cycles required to cause the tooth to shed.
