The Hawley retainer includes a metal wire that typically surrounds the six anterior teeth and keeps them in place. The labial wire, or Hawley bow, incorporates 2 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 minor movement of the anterior teeth as needed. A hawley retainer is very common across multiple age groups. In fact, most people – children and adults – need to wear them for a period after their braces are removed.
