Abstract: A supplementary device is provided for sliding operation for use in a device for correcting teeth irregularities. The supplementary device abuts a bracket, and has a wire-engaging slit having the same shape as a slit in the bracket so that a wire engaged in the bracket can also be engaged in the slit. The supplementary device has a pair of protrusions which forms a T-shape. The projections are used to anchor a rubber band. The supplementary device is slidable along the wire and slides until stopped, for example by the bracket.

Abstract: An indicator for using in setting a device for teeth irregularities including a wire extending along with a dentition, a bracket in which the wire is inserted, the bracket being fixed to a surface of each tooth in a manner that a pillow-like shaped base plate is interposed between the bracket and the surface, the indicator including: a backbone member extending along with a longitudinal axis in the tooth; a leg member connected with a lower end of the backbone member; a first arm member connected with an upper end of the backbone member, the first arm member extending parallel to the leg member; a device for carrying the bracket for slidably carrying in a slidable manner, the device being connected with the backbone member at intermediate portion of the backbone member; and at least one second arm member connected with the backbone member at intermediate portion between a position where the means is connected and another position where the leg member is connected the second arm member extruding parallel to th

Abstract: A device for correcting teeth irregularities includes a bracket to be fixed on a tooth. The bracket has a slit, and a base plate is interposed between the bracket and the surface to be fixed to the tooth. A wire is inserted into the slit and engaged with the bracket. The base plate has a thickness which is in a range of 0.5 to 5 mm, and the base plate is composed of an easily plastically deformable resin on a surface to be fixed to the tooth. The base plate is capable of deforming to allow the bracket to be inclined at an angle relative to the vertical direction.

Abstract: A supplementary device for use in a device for correcting teeth irregularities includes a bracket having a slit with a T-shaped section and a wire to be inserted into the slit and engaged with the bracket. The wire has an elongated projection, and the supplementary device includes a wire engaging slit having substantially the same shape as the slit in the bracket. At least one protrusion is adapted for engaging a resilient band, and the bracket is slidable along the wire.
