Tratamento da classe III com mini implantes: revisão de literatura

Abstract

Class III is morphologically characterized by the mesiocclusion of the 1st permanent lower molar in relation to the 1st permanent maxillary molar. The mini-implants are made up of 3 parts, namely: head, upper region of the screw where the elastics, springs or ligature wire and transmucosal profile are attached. Among the possible treatment mechanics, there is the use of orthodontic appliances, extractions and mini implants as anchorage, which allows the correction of malocclusion of the arches, allowing a more conservative treatment in relation to the surgical approach, while still being effective and stable. Thus, this literature review study aimed to describe the treatment of class III with mini implants. The bibliographic survey was carried out in the following databases: SciELO, PubMed, still used, books and monographs. Descriptors and their synonyms in Portuguese and English were searched: Angle Class III, Orthodontic Anchorage Procedures, Mini-Implants. According to the literature consulted, mini implants proved to be a good indication for the treatment of class III malocclusion, promoting a class I molar and canine occlusion, as well as excellent intercuspation, with ideal overjet and overbite, corrected midline deviation and teeth well aligned.
