Bionator de balters no tratamento ortopédico da má oclusão Padrão II, deficiência mandibular - revisão de literatura

Abstract

The morphological classification described by Capelozza Filho, Pattern II is characterized by an increased maxillomandibular sagittal step, short chin-neck line and increased facial convexity, and in most cases, the mandible is the structural component involved in the formation of this malocclusion. Mandibular deficiency is frequently observed in around 33.10% in primary dentition and in 41% in permanent dentition in Pattern II individuals.Due to this high prevalence, the objective of this study was to carry out a literature review on the functional orthopedic treatment of Pattern II individuals, mandibular deficiency with the Balters Bionator appliance, involving the description of the appliance, mechanism of action and its effects, as well as its effectiveness.Scientific databases such as Scielo, PUBMED, Google Academic and Scientific Magazines were researched, in addition to books in the area.Through a review of the literature, we concluded that the Balters Bionator proved to be one of the transmitted orthopedic devices most used in the treatment of mandibular deficiency, with satisfactory skeletal and dental results, with a more anterior positioning of the mandible and, consequently, a correction of the malformation occlusion. Studies carried out show its effectiveness when used for a correct period of time and especially during the growth phase, which can be observed by means of carpal radiography.
