Abstract: A mordida aberta é uma anomalia com características distintas que, além da complexidade dos múltiplos fatores etiológicos, traz consequências estéticas e funcionais. Muitas alternativas têm sido utilizadas em seu tratamento, entre elas a grade palatina, for as ortopédicas, ajuste oclusal, camuflagem com ou sem exodontias, mini-implantes ou miniplacas e cirurgia ortognática. O diagnóstico preciso e a determina o da etiologia permitem estabelecer os objetivos e o plano de tratamento ideal para essa má oclus o. O presente relato descreve o tratamento de uma má oclus o Classe I de Angle, com padr o esquelético de Classe II e mordida aberta anterior, realizado em duas fases e que foi apresentado à diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO), representando a categoria 2, como parte dos requisitos para a obten o do título de Diplomado pelo BBO. Open bite is an anomaly with distinct characteristics which, in addition to involving complex, multiple etiologic factors, entails aesthetic and functional consequences. Many alternative approaches have been employed to treat open bite, including palatal crib, orthopedic forces, occlusal adjustment, camouflage with or without extractions, mini-implants or mini-plates, and orthognathic surgery. By determining accurate diagnosis and etiology professionals can set the goals and ideal treatment plan for this malocclusion. This report, describing the two stages treatment of a Angle Class I malocclusion with Class II skeletal pattern and anterior open bite, was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), representative of category 2, as partial fulfillment of the requirements for obtaining the title of BBO Diplomate.

Abstract: purpose: to determine the occurrence of anterior open bite and harmful oral habits in children from four to six-year old. methods: a total of 266 four-to-six-year-old male and female children in the city of suzano (s?o paulo, brazil) were evaluated. an assessment chart for detecting the occurrence of harmful oral habits was administered to the guardians and clinical exams were performed for assessing occlusion in the children. results: a total of 221 children (83.1%) had at least one harmful oral habit, the most frequent of which was the use of a feeding bottle (n=167; 75.6%). the occurrence of simultaneous harmful habits and dental occlusion abnormalities was observed in 119 children (44.1% of the sample); among these children, the greatest prevalence was of anterior open bite (n=89; 79.8%). conclusion: anterior open bite was the most prevalent occlusion alteration in the children and had a statistically significant association with harmful oral habits, such as the use of a bottle and/or pacifier and teeth grinding.

Abstract: the objective of this work was to verify the prevalence of malocclusions (anterior open bite, overjet) and its association with age, gender and type of school with a sample of 2,651 preschool children in the city of recife, pe, brazil. the children were seated in school chairs in the room of the day care/school for the clinical exam, children aging two years or less were assisted in the system knee-knee, through natural and artificial illumination. the dental protrusion was verified when the overjet was larger than 3 mm through periodontal probe in millimeters. the presence of anterior open bite was detected when there was no contact with the anterior teeth and the posterior ones stayed in occlusion. t was also registered in clinical record a combination of the two malocclusions types, in other words, open bite and of dental protrusion. the data were analyzed at qui-square and the association among the events was the odds ratio. the prevalence of protrusion was 66.1% and previous open bite 19.8%. there was association among this malocclusions, age and type of school, however there was not significant statistical association between malocclusion and gender. it was concluded that the prevalence of malocclusion in preschoolers was high and it was associated to the age and school type.

SINDROME DE COLAPSO DE MORDIDA POSTERIOR

Acta Odontológica Colombiana , 2012,
Abstract: El Síndrome de Colapso de Mordida posterior es una patología oclusal que se presenta como consecuencia de problemas dentales, periodontales y oclusales, que exige la correcta evaluación de los signos y síntomas que lo caracterizan. El objetivo del artículo es describir la manera como evoluciona la enfermedad, la evaluación multidisciplinaria para obtener un diagnóstico preciso y la secuencia de tratamiento integral, revisando los conceptos para un mejor entendimiento del tratamiento periodontal y restaurativo que requieren los pacientes con síndrome de colapso de mordida posterior; caracterizado por procesos patológicos como enfermedad periodontal, caries dental con subsecuente alteración de la integridad del arco dentario que genera perdida de soporte posterior conllevando a un trauma oclusal secundario y disminución de la dimensión vertical oclusal. El control del proceso inflamatorio y la estabilización periodontal son puntos de partida indispensables en el tratamiento integral del paciente. La migración patológica de los dientes y las alteraciones del plano oclusal pueden exigir la corrección ortodóntica de los arcos y en algunos casos el concurso de cirugía oral para la nivelación del plano oclusal. La secuencia organizada del tratamiento por fases permite la restauración predecible de los pacientes con este síndrome, tomando en cuenta las diferentes alternativas protésicas tanto removibles como fijas con o sin implantes de oseointegración, para el éxito integral a largo plazo.

Revista de Odontologia da Universidade de S?o Paulo , 1998,
Abstract: A pesquisa teve como objetivo determinar as for as de mordida de 73 indivíduos, por meio de um gnatodinam metro. Os pacientes eram portadores de próteses parciais removíveis inferiores classes I, II ou III. A arcada antagonista era prótese, parcial removível ou fixa, ou total. Os resultados permitiram concluir que: as selas de extremidade livre, principalmente em suas posi es extremas, conduziram a for as de mordida muito baixas; o envolvimento de prótese total, também, conduziu a for as de mordida baixas; o sexo masculino alcan ou valores maiores que o feminino; com prótese parcial removível classe III, os dentes naturais molares e pré-molares desenvolveram valores maiores do que com classes I e II.
