A simplified lingual technique.

In increasing number of patients, especially young adults, are asking for esthetic alternatives to conventional orthodontics in the treatment of problems related to malalignment of the anterior teeth. One such method is the Idea-L system, an efficient, simplified lingual technique that can be useful in cases of mild-to-moderate anterior crowding, post-treatment crowding relapse, late dental crowding, and anterior tooth spacing. Treatment with the simplified lingual technique may require interproximal enamel reduction (stripping), depending on the severity of crowding, the shape of the incisors, and the Bolton Index. The limitations of this method are that it can be used only in cases requiring minimal torque control of the anterior teeth and that it does not correct malocclusions in the posterior segments. The Idea-L system consists of standard .018" x .025" edgewise lingual brackets that can be bonded from first premolar to first premolar or from canine to canine in either or both arches. The morphology of the bracket wings allows simple and effective placement of Slide ligatures, which transform the bracket slots into tubes for orthodontic movement with minimal friction. When friction is required (as in correction of rotations), the Slide ligatures can be replaced with elastomeric or stainless steel ligatures. Because the brackets are small (1.6mm wide) and thin (1.4mm), patient comfort is enhanced (especially when used with Slide ligatures), speech is not hampered, and impingement of the soft tissues, particularly the tongue, is minimized. The reduced thickness of the Idea-L brackets allows placement closer to the incisal edge, where the flat anatomy of the anterior teeth permits better adaptation and adhesion of the bracket base compared with the cingulum area.6 The absence of gingival hooks on the Idea-L brackets reduces tongue discomfort and facilitates oral hygiene.
