Today ten years later the authors present the progress which have been realized: the evolution of the brackets, the accuracy of their placement in the lab procedure with the new targ, the making of the wire, the patient's comfort increase. The placement brackets are customized by making an anatomical resin pad. Placement of the brackets have evoluted from a quantized system in two dimensions (Targ 1) to a no quantized system in three dimensions (Class System) and finally to a real quantized system in three dimensions (Targ 2 with a compass of thickness with measures the first order band). Data System DALI (Drawing Arch Lingual Ideal) allows to draw the exact design of the wire. A video tape shows the different laboratory and clinical phases. By using light cured periodontal protection like Barricaid from Caulk: the patients have a greater adaptation with their appliance. All this progress give to lingual orthodontic credibility. Lingual is a reality to day and it's the first concept with customized brackets extremely accuracy, full quantized in the three orders, using the computer progress.
