<p>This invention relates to a wire-tensioning and/or -fixing orthodontic device comprising a bracket having preferably a bearing eye, a wire-engaging shoulder, and a retaining member which is rotatably mounted in the bearing eye and adapted to retain a correcting wire in engagement with said wire-engaging shoulder. For use in the lingual technique, the orthodontic device can be further miniaturized in that the base portion of the bracket has no flange arms and is secured to a backing pad and the latter is provided on the side opposite to the bracket with a metal fabric adapted to be adhesively fixed to a tooth. The backing pad comprises outwardly extending side arms (rotation-inducing arms, adaptation-inducing arms and activating arms), which are adapted to be activated by being bent.</p> |
