<p>In an orthodontic bracket 1, 101, 201 including a base part 2, a bracket body 3 which is fixed to the base part 2, and a clip 4 having a substantially U-shape in section which is mounted on the bracket body 3 so as to move, an archwire slot 5 in a shape of a groove which can contain an archwire is provided on an upper face of the bracket body 3, a guide groove 9 for guiding a lower extended part 42 of the clip 4 is formed on a lower face of the bracket body 3, and the guide groove 9 is provided at a position below the archwire slot 5. In a state where the slot is closed, an end 45 of the lower extended part 42 of the clip 4 does not pass through the bracket body 3 up to a side face at an opposite side to the curved part of the bracket body 3. In this manner, it is possible to provide an orthodontic bracket which has a lower height and has less possibility that a clip may be detached.</p> |
