The Cusp-Lok I Low Profile bracket features 3/4 inch 14k gold chain attached to a stainless steel orthodontic bracket. Low Profile refers to the first link of chain attached parallel to the bonding pad, eliminating the "bump" of tissue in these cases. The chain is kind to tissue, and is selected specifically for its ease of use in the impacted cuspid procedure. The Cusp-Lok I Low Profile is best for applications with the facial surface or cuspids.
