Ace the Braces: 2026 Contemporary Ortho Appliances Challenge – Get Wired for Success!

A Lingual Holding Arch is a fixed space-maintaining appliance placed on the lingual (tongue) side of the lower arch. It attaches to the mandibular first permanent molars with bands and connects them with a wire that runs along the lingual surfaces. Its clinical purpose is to keep the molars from drifting mesially so there is enough space for the eruption of posterior teeth (premolars and canines) and to preserve overall arch length during mixed dentition. It is not used to widen the arch or to correct tongue thrust, and it is distinct from palatal appliances that sit on the palate.
