A lingual arch is used to almost magically reduce crowding without the need to extract teeth. It utilizes “Leeway space” or the fact that certain deciduous teeth are larger than permanent teeth to make the correction.

A lingual arch is an orthodontic device which connects two molars in the upper or lower dental arch. The Lower Lingual Arch (LLA) has an arch wire adapted to the lingual side of the lower teeth. In the upper arch the arch wire is usually connecting the two molars passing through the palatal vault, and is commonly referred as “Trans Palatal Arch” (TPA).

LLA and TPA are fabricated by placing bands on the molars. These are connected to the arch wire. The wire can be soldered to the bands or inserted into lingual sheaths welded to the molar band (removable LLA and TPA).

It is easy for patients to wear, and is scientifically validated!
