3D Lingual arch
Some adjustments can be made during treatment with the Lingual Arch. This accessory is a removable lingual wire that is used to maintain bilateral or unilateral expansion on the lower arch, among other uses. It also enables labializing incisors or provides additional anchorage when treatment requires important teeth movement. The Lingual Arch can be fitted on the upper maxillary in order to fabricate a removable Nance button.
