Purpose: This article reports various applications of tandem archwire techniques for alignment, leveling, space closure, and finishing during lingual orthodontic treatment.

Methods: Most available lingual brackets are single-slotted and each bracket system has its unique design. Some brackets such as Kurz, STb, Clippy-L and Harmony have a lingually opening slot and other brackets such as Evolution and self-ligating STb have an occlusally opening slot. Incognito has both occlusally opening and lingually opening slots, which are installed in anterior and posterior brackets, respectively. Because multi-slotted lingual brackets such as Fujita lingual bracket and Anboini have both lingually opening and occlusally opening slots, they make use of tandem archwire technique, in which two archwires are engaged simultaneously in both occlusally and lingually opening slots.

Results: Using tandem archwire techniques, multi-slotted lingual bracket overcomes the disadvantages of narrow lingual brackets in lingual orthodontics.

Conclusion: These advanced techniques not only prevent undesirable reaction forces from becoming manifest, but also make treatment simple and efficient for both the clinician and patient.

Key words: Multi-slotted lingual bracket, Lingually oening slot, Occlusally opening slot, Tandem archwire technique
