Perfect for permanent fixed-lingual retainers. Features a very thin, rectangular wire that can be adapted with no occlusal interference while ensuring patient comfort. Does not unwind when cut and prevents inadvertent tooth movement associated with active-force wires. This 3-strand, stainless steel, braided retainer wire is annealed, or dead-soft, so that it can be easily formed and hold bends to make bondable lingual retainers. Made in the USA.
