Abstract: 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.

Abstract: The invention relates to a device (1) for extracting a tooth root, said device having a pin (2) which can be inserted and fixed in the tooth root (10). The pin (2) can be fixed to the front end of a unit (5) via a connection piece (3). The unit (5) can transfer an impact force to the pin (2) in the direction of extraction (A). The device enables an especially simple operation, without clearance problems or danger of injury in the mouth area, particularly on account of the good access to the tooth root provided by the connection piece, which is designed as a thin connection rod.

Abstract: The invention relates to a method for extracting a root, whereby the root is extracted following a possible initial loosening of the root within the periodontal gap. A pin is inserted into the root and affixed there, whereafter a pulling element functionally linked with a tensioning device is connected with the pin. The pulling force required for extracting the root is subsequently applied to the root substantially in the direction of the axis of the tooth by means of the tensioning device that has been partially inserted into the mouth and supported there.

Abstract: In order to extract a root of a tooth, this root (12) is drilled by a pin projection (8), which has a smaller diameter and is coated with an abrasive material. Afterwards, a threaded pin is inserted by rotation into the opening in the tooth made by the pin projection. As a result, the threaded pin whose upper part is provided with a lug is sufficiently anchored whereby enabling an extraction in the longitudinal direction of the tooth to be reliably carried out.

Abstract: The invention relates to a method for extracting a root, which is characterized in that a pin (2) is inserted into and fastened in the root of a tooth. A tension element (3) that is functionally linked with a manually actuated tensioning device (4) is introduced into the pin (2). The tensioning device (4) that is partially introduced into the mouth and supported therein generates the pulling force required that acts upon the root in a substantially axial direction of the root. The invention allows for a very simple and effective method and device for extracting the root of a tooth.
