Made in the USA, our 3 Strand Lingual Retainer Wires are made from a fully annealed 302 Stainless Steel 3 Strand wire, developed specifically for permanent or semi-permanent retention. Fully annealed, the softness allows for easy bonding to teeth in even the most intricate of formations, as well as avoids inadvertent tooth movement associated with active force wires.  Available in a 5 pack of 6" straight lengths.
