Abstract
I started lingual orthodontics in 1980s. At that time lingual orthodontics, as well as doctors practicing it, used to be criticized and misunderstood. Despite that, I continued lingual orthodontics and in 1986 when I retired the Nippon Dental University, I was treating about 40 cases annually.
Almost 20 years have passed since then, and now the bias and misunderstanding about lingual orthodontics are reduced. However, still some orthodontists criticize it and others accept their opinion.
I treated several 8 -tooth extraction cases, which requires the highest technique for orthodontic treatment, either lingually or labially. The difference between the two treatments was reviewed in terms of the length of treatment period and the result. One of the cases treated lingually is presented.
