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.
