The present invention relates to an anchorage for orthodontic treatment, which is configured to easily connect a traction member such as a wire or a spring, and prevent the traction member from escaping. The anchorage for orthodontic treatment according to the present invention comprises an anchorage body having a screw hole for insertion of a screw for fastening the anchorage into an oral cavity; and a spiral holding ring formed at the anchorage body to connect the traction member. The spiral holding ring is formed into a closed ring shape when viewed along the axial direction of the spiral holding ring. According to the present invention, the anchorage for orthodontic treatment, fastened into the oral cavity by a screw, has the spiral holding ring, and therefore the traction member can be connected through the space formed by an end (free end) of the spiral holding ring, thus effectively preventing the traction member from escaping and providing stable traction force. |
