Hawley Retainer
The best-known type is the Hawley retainer, which includes a metal wire that surrounds the teeth and keeps them in place. Named for its inventor, Dr. Charles Hawley, the labial wire, or Hawley bow, incorporates 2 omega loops for adjustment. It is anchored in an acrylic arch that sits in the palate (roof of the mouth). The advantage of this type of retainer is that the metal wires can be adjusted to finish treatment and continue moving teeth as needed
