Tratamento orto-cirúrgico da má oclusão classe III: revisão de literatura

Abstract

Class III malocclusion is a type of occlusal relationship determined by Angle as a relationship between molars, where the mandibular first molar occludes the maxillary first molar mesially. Such occlusal alteration may have dental or skeletal origin, in addition to having different levels of severity for each individual, directly influencing the choice of treatment. For milder and some moderate cases, skeletal class III malocclusion can be camouflaged by means of compensatory orthodontic treatment associated with extraction of lower premolars. However, for severe cases, this treatment does not have satisfactory functional and aesthetic benefits, and the surgical protocol associated with orthodontics is more indicated. Thus, it is essential to consider the bone discrepancy, the patient's age and their expectations with the treatment to determine the most appropriate conduct. The objective of this study is to evaluate the benefits of the association between surgical and orthodontic protocols for the treatment of class III malocclusion of skeletal origin. This work consists of a qualitative descriptive literature review, with a search for articles in Pubmed/Medline, VHL and Google Scholar databases. In the present study, it was identified that the ortho-surgical treatment is capable of treating the most severe cases of skeletal class III malocclusion, achieving a more immediate and aesthetically satisfactory result, guaranteeing aesthetic, functional, psychosocial gains and improved sleep in cases of maxillary retrusion
