Lower Bonded Retainer

Maintenance of incisor alignment is a significant problem, even in well-treated cases with patients at risk being difficult to predict. The relapse occurs due to the gum fibers pulling the teeth toward their "old crooked positions" because of the natural narrowing of the dental arches as we age and because of growth. The bonded lower retainer is a proven method to minimize relapse. The University of Washington Group studied changes of incisor irregularity 10 to 20 years post-retention and concluded that the majority of the relapse occurs during the first 10 years; and for this reason, it is best to retain with a semi-permanent retainer during the teen years and early 20's. I advocate leaving the 3x3 retainer for a lifetime if oral hygiene is adequate.

Jon Artun and the University of Washington Group also report that there is no risk of gingivitis or caries associated with long-term use provided that the lingual bonding is trimmed to avoid impingement and undercuts.


Completely Adjusted 3x3 Wire


A lingual retainer that is bonded only to the cuspids can be flossed by placing the dental floss on each side of the lower incisor and working the floss toward the gum. The patient also needs to spend extra time brushing the back of the lower incisors.

Upper Bonded Retainer

Upper bonded wires are recommended in cases where the upper incisors were severely rotated or if there were large spaces between the upper teeth. Upper bonded wires are placed to help prevent relapse, and they should be maintained for a lifetime if oral hygiene is adequate.
