ABSTRACT:
The present invention relates to an orthodontic appliance to treat irregularities of teeth by attaching an arch wire holder to a plurality of teeth and then connecting one or more orthodontic wires to the arch wire holders. The bracket constituting an arch wire holder is provided with an arch wire fixing slot formed with a specified radius of curvature approximately conforming to the diameter of the arch wire. The curvature radius of the arch wire fixing slot is determined by the purpose of application, namely, it depends on whether it attaches onto the outside (buccal side) surface or the inside (lingual side) surface of the teeth, and for which teeth it is employed. This arch wire holder is especially effective when the bracket is attached to the inside of the teeth for orthodontic purposes, for it then allows the application of corrective forces on the teeth without being easily visible in the user's mouth.
