An exemplary embodiment of the present invention is directed to a malleable flattened rectangular lingual retainer wire that is configured to be integrally shaped and bonded to the inside surfaces of teeth for a prolonged period of time. The lingual retainer wire acts to secure the teeth to one another in a manner that provides precise root position control. The lingual retainer wire is a single strand of wire that has been flattened in order to reduce its profile allowing the lingual retainer wire to be placed on the inside of either the upper or lower incisor teeth without interfering with occlusion.
