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.

In the lingual orthodontic technique, there are two paradigms regarding the type of wire used. Regardless of the material or gauge, some orthodontists choose to use the straight wire and resin and bond it to the surface of the tooth; they call it compensations. Other orthodontists prefer to bend the wire, giving it a mushroom shape. There is no specific indication for the use of each type of wire, so orthodontists use them according to their criteria. The present study establishes the bases so that it is possible to find the indications for each type of wire. A clinical trial of a lingual orthodontic patient was used. To carry out the comparative study, a straight arch was placed in his right arch and a mushroom arch in the left arch. Using 3D imaging, a high-biofidelity biomodel of the patient’s mandible was generated, with which the FEM analysis was performed, which allowed comparing the reactions of the mandibular bone and appliances with the different arches. It was found that, on the side with the straight arch, there were greater deformations, and in the mushroom arch, there were greater stresses. With this, it is possible to find which clinical cases in each type of wire are indicated.

Introduction: Adult and young adult patients have been increasingly seeking for orthodontic treatments and almost all of them want it to be done by an aesthetic appliance with maximum invisibility. The lingual technique has emerged in the late 1970s and has now become a very viable alternative to perform orthodontic treatments, however, many cases of treatment or retreatment involve correction through orthognathic surgery. The surgical technique is more sedimented and simplified as a great aid in the correction of skeletal discrepancies. Objectives: This article aims to show the correction of malocclusion and discrepancy between dental arches, with the lingual orthodontic technique and the surgical association. Conclusion: It is possible to provide to the patient an adequate correction of malocclusion, maintaining the desired aesthetics through the lingual technique and orthognathic surgery

ABSTRACT Objective: This study aims at identifying anatomical dimensions of dental arches, based on landmarks currently used in the lingual orthodontic technique, and create an archwire form template to be used in orthodontic clinics. Methods: Maxillary and mandibular dental casts of 140 Caucasian individuals with natural and normal occlusion were digitized (3D), and the images were analyzed with Delcam Power ShapeTM 2010 software. The dental arch shapes and sizes were obtained from 14 landmarks selected on the lingual surface of the teeth. Points and segments defined by the software were used to create an archwire form template. Results: Various dental arch patterns were found for both maxilla and mandible. The smallest sizes were found in females, and the largest were found in male subjects. Six categories were defined for each gender, three for the maxilla and three for the mandible (Small, Medium and Large). A template was created with eighteen anatomic lingual archwire designs, nine for the maxilla and nine for the mandible, for both genders. Conclusions: Landmarks evaluated in this study showed dental arch differences between genders. This information enables making orthodontic lingual archwires that are more compatible with the anatomical forms and sizes of the maxilla and mandible. The findings also allowed the creation of a template for an anatomic lingual metallic archwire form to be used in the lingual technique.
