Mordida cruzada posterior vestibular: revisão de literatura

Abstract

Satisfactory occlusion consists of the harmonic relationship between the superior and inferior arches, where the palatal cusps of the superior premolars and superior molars occlude in the central pits of the inferior elements. In disharmonious alterations, we have the vestibular posterior crossbite (Brodie's syndrome), it is a malocclusion that affects the posterior elements, being characterized by the vestibularization of the superior posterior elements and/or by the lingualization of the inferior posterior teeth, which may be unilateral, bilateral or localized. Thus, the general objective that guided this research was to clarify the posterior vestibular crossbite, its etiology, forms of diagnosis and treatment. Therefore, a literature review was carried out, with bibliographic research in the VS, MEDLINE/PubMed, LILACS and SCIELO databases, which included published articles, narrative review studies, clinical case reports, systematic literature reviews, meta-analyses, clinical studies and experimental studies in animals, which had a direct or indirect relationship with the main theme. Experimental laboratory studies and unpublished studies were excluded. It is concluded that Brodie syndrome affects between 0.5% and 1.1% of the population. It can be treated with orthopedics, orthodontics and/or orthognathic surgery, with the correct diagnosis being essential for the definition and success of the treatment plan. Therefore, it is important that professional dentists and dentistry students understand the particularities of posterior vestibular crossbite, forms of clinical presentation and treatment, in order to ensure the best result for the patient.
