Class III treatment with buccal shelf

Abstract

Class III is classified as a mesiobuccal cusp of the maxillary first molar that occludes in the distobuccal groove of the mandibular first molar. Class III malocclusion and mandibular prognathism have been reported as synonyms and may be related to different skeletal and dental positions. The diagnosis of Class III should be made taking into account cephalometric findings to provide information about the skeletal and dental components and facial analysis. For a long time, orthodontists avoided early treatment of Class III because they believed that it was caused primarily and primarily by excessive growth of the mandible, which led to inevitable surgical treatment in most cases. The use of mini-implants has become an ally of orthodontists seeking to correct Class III in patients who do not want to undergo orthognathic surgery. If administered correctly, extra-alveolar mini-implants play a very important role in skeletal anchorage in relation to Class III compensatory treatment, since the assistance provided by the technique itself is based on anchorage during vestibularization of the upper teeth and mainly the lower teeth, preventing sudden lingualization movements, thus avoiding surgeries in adult patients with profiles that are not very compromised by malocclusion.
