An orthodontic band for use with orthodontic arch brackets is disclosed which comprises an elongated substantially flat strip of elastic material. The band is suitable for use for moving misaligned teeth from an actual to a desired position. The elastic strip is provided with a plurality of elongated apertures each of which is positioned in the region of a respective bracket - the strip engaging the bracket by passage of the latter through the apertures. The apertures are movable from a first position or an angular orientation in which at least a portion of the elastic strip is under tension to a second position in which the elastic strip is free of tension. The apertures are so arranged and positioned on the strip so that when the apertures are placed in a first position while associated with a respective bracket, tension is applied to the bracket and the band urges the tooth to move towards its desired position. A method of preparing the orthodontic band is described.
