<p>An orthodontic band (10) for placement on a molar tooth comprises a strip of flexible material (11), such as a stainless steel strip, having co-operating locking means (12, 13) located adjacent each end of the strip. Alternatively, the strip (60) may have an elongate tongue (62) formed at one end and slots (63, 64) for receiving the tongue at the other end. In use, the band is formed into a shape that will fit over a tooth and placed over the tooth. The band is then tightened to cause the band to closely fit to the tooth. An orthodontic cement is placed between the band and the tooth. The locking means (12, 13) on the band provides a frictional fit that may be sufficiently strong to hold the band in the desired configuration until the cement has set. Alternatively, the clamp may need to stay in place until the band and cement can provide a permanent set.</p> |
