Preformed orthodontic bands with welded attachments [10] largely replaced both the lasso wire and the threaded pin in our protocol. Clinical experience with these bands showed them to be considerably more compatible with ensuring the health of the periodontal tissues. As with the lasso wire, the use of a band dictated a very wide surgical clearance of tissue on all sides of the tooth. However, in order to permit the introduction and cementation of the band, it was imperative, at the time of placement, to adequately control haemorrhage around the crown and to avoid contamination from oozing blood inside the cement‐filled band.
