A removable device that enables us to keep proper spacing of the teeth during premature loss of baby teeth, caused by cavities or other problems. Usually, it’s necessary to wear it until permanent teeth emerge.

The lingual arch is an orthodontic device that connects the two molars in the upper or lower jaw. The lower lingual arch (LLA) has a wire aligned on the lingual side of the lower teeth. In the upper jaw, the wired joint usually connects the two molars and passes through the palate and is referred to as the transpalatal arch (TPA).

The main purpose of the TPA device is to maintain an ideal teeth arrangement and to prevent the rotation of the molars. Additionally, this method opens up more space in your mouth. Many studies show that TPA treatment is an excellent method of maintaining a proper space between the teeth.

Lingual arch is used actively or passively. The device allows for greater control of the movement of the teeth, especially in the target areas. The treatment is used to:

  • Stabilize and support the molars, thus avoiding possible irregularities
  • Maintaining proper space in your mouth
  • Control of “empty spaces” after the loss of baby teeth and before permanent teeth emerge
  • In the case of a removable braces, the lingual arch can move the molars to the desired position
  • Expanding or decreasing the space between the premolars, thus affecting the rotation of the molars
  • Can serve as a retainer


When is the lingual arch used?

Usually used in premature loss of baby teeth. It can be used to correct the space between the teeth.

Depending on your diagnosis, the length of the treatment varies. Our orthodontic specialist, Dr. Ana Parčina, will remove the device as soon as permanent teeth emerge. It does not require additional extraction of permanent teeth, which makes treatment less serious than others.
