A utilização do mini-implante extra-alveolar no tratamento ortodôntico da classe III: revisão de literatura

Abstract

Class III malocclusion is a dentoskeletal deformity that affects many individuals and has a multifactorial etiology. In orthodontics, the treatment of this type of malocclusion is challenging, being even more complex in young and adult patients. In this context, mini-implants appear as an auxiliary method in the compensatory treatment of Class III malocclusion. These are classified according to the insertion site in intraradicular or extra-alveolar. This study aims to discuss through a literature review on the use of extra-alveolar mini-implants in the compensatory treatment of Class III malocclusion. The methodology applied was to data collection carried out in the databases related to the health sciences Lilacs, Scielo, Pubmed/Medline and VHL. The inclusion criteria were clinical research, theses, dissertations, clinical cases, systematic literature reviews, meta-analyses, experimental research on animals, while the exclusion criteria were literature review papers after the search deadline and laboratory research involving tests in vitro. Extra-alveolar mini-implants enable Class III compensatory treatment through distalization of the entire anterior mandibular arch and have advantages such as maximum anchorage, low cost, independent of patient

cooperation and stable results. Therefore, it is concluded that extra-alveolar mini- implants contribute to the satisfactory treatment of Class III malocclusion, achieving maximum anchorage, reducing the need for extractions and orthognathic surgery, achieving occlusal balance and changing the patient's facial profile treated.
