1. An implant fixture remover comprising:
a remover screw including a first thread formed on one side thereof to be screwed to a female screw portion of an implant fixture implanted into an alveolar bone, and a second thread formed on the other side thereof; and, a remover driver including a torque transmitting portion slide-inserted into the remover screw, and a torque providing portion formed to be separated from the torque transmitting portion and screwed to the second thread so that the torque transmitting portion maintains contact with the fixture, wherein a force, which is applied to facing surfaces of the torque providing portion and the torque transmitting portion by a torque generated by turning the torque providing portion after the torque providing portion is screwed to the second thread, is transmitted to the fixture through the torque transmitting portion and works as a repulsive force so that the fixture is extracted from the alveolar bone, whereby the torque transmitting portion is pressurized toward the fixture. |
