Abstract
Disclosed is an implant fixture remover. The fixture remover includes a remover screw which has 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 which is slide-inserted into the remover screw, and a torque providing portion which is separated from the torque transmitting portion and screwed to the second thread so that the torque transmitting portion maintains contact with the fixture.
Claims13
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 onto the remover screw, and a torque providing portion formed to be separated from the torque transmitting portion and directly screwed to the second thread so that the torque transmitting portion maintains direct contact with the fixture,
- wherein a degree of slide insertion of the torque transmitting portion onto the remover screw is determined based on a degree of direct screw coupling of the torque providing portion and the second thread,
- 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 directly 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, and
- wherein the torque transmitting portion is pressurized toward the fixture in a direct contact state with the fixture.
