Abstract
Disadvantages of lingual treatment were exaggerated and there have been many orthodontic specialist who do not believe in lingual orthodontics. I will mention several advantages of lingual treatment over labial, showing 2 cases treated by lingual orthodontics.
Case 1 is Class II, div. II and upper bilateral first bicuspid extraction case. This show that the lingual orthodontics is easy to correct overbite due to bite-plane effect.
Case 2 is Class I crowding case and upper bilateral second bicuspids were already loss. This show less frequent extraction owing to lingual tip of the lower incisors.
