Abstract :
Lingual orthodontics have stormed the world of orthodontics over the past few years with its esthetic superiority. But apart from its invisibility, this technique has very significant superiority in non extraction line of treatment where space is a requirement. This article is aimed at describing a case report of a 12-year-old girl who with almost 180 degree rotated upper left central incisor with its palatal surface facing labially. With the lingual technique the derotation of rotated incisor was completed. The incisors maintained the axial inclination without disturbing the profile. This proves that apart from the esthetic superiority, the lingual technique has the greatest advantage of its biomechanics in preventing unwanted proclination of anteriors, thus serving as the ultimate choice of treatment in non- extraction treatment.
