This cuspid-to-cuspid banded lingual retainer can be made either from your preformed bands or our custom-fit bands. The lingual wire is carefully adapted for direct contact with the lingual surfaces of each anterior tooth...and is typically placed 2mm below the incisal edge. Note: Recent research shows that it is necessary to bond each tooth individually to maintain them in their corrected position. Individual anterior teeth can be secured to the lingual wire by simply adding composite over the lingual wire.
