ABSTRACT

Una de las consecuencias de la desprogramación neuromuscular es la rotación mandibular en sentido horario, evidenciando el punto prematuro de contacto y aumentando la dimensión vertical del paciente. En pacientes clase II con componente vertical, es un problema realizar este tipo de tratamiento, ya que por lo general este efecto de posterorrotación mandibular hace el perfil más convexo, y en algunos casos genera mordida abierta anterior, la cual se debe corregir posteriormente con el tratamiento de ortodoncia, cirugía o prótesis, lo que alarga el tiempo total de tratamiento por la necesidad de control vertical. El presente caso se trata de una mujer de 45 años de edad, dolicofacial, con tendencia a mordida abierta, mordida dual, sobremordida vertical y horizontal disminuidas, motivo de consulta dolor articular, el cual no le permite continuar con sus labores diarias, el tratamiento realizado fue desprogramación neuromuscular con un guarda oclusal inferior con el propósito de aliviar sintomatología articular y control vertical con microtornillos palatinos previo a tratamiento ortodóncico (AU)


One of the effects of the neuromuscular deprogramming treatment is the mandibular clockwise rotation, making the light premature occlusal contact more evident and increasing the patient vertical dimension. In Class II patients with vertical component is difficult to treat them due to profile worsening as an effect of the clockwise rotation creating in some patient's anterior open bite, this has to be corrected later in treatment with orthodontic intrusion, surgery or prosthodontic treatment, increasing the total time of treatment with the vertical control necessity. This case report is a 45 years old patient, dolichofacial, with anterior open bite tendency, dual bite, decreased overjet and overbite, her chief complaint was temporomandibular joint dysfunction which dont allow her to do her daily duties, the treatment for her was neuromuscular deprogramming splint for the temporomandibular joint pain, and vertical control with temporary anchorage devices (miniscrews) before the orthodontic treatment (AU)

ABSTRACT

RESUMEN: El apiñamiento en edades tempranas, se refleja cuando el tamaño dental no coincide con la longitud de arco. De este modo, resulta importante determinar si la expansión del maxilar podría solucionar por sí solo el problema de apiñamiento en el sector anterior, teniendo en cuenta que este tratamiento es uno de los más antiguos y que comúnmente se ha enfocado en la resolución de alteraciones transversales en dientes posteriores empleándose a edades tempranas. El objetivo fue determinar si la expansión maxilar es efectiva o no, en la corrección del apiñamiento en dentición mixta mediante el análisis de la evidencia disponible. Se realizó una revisión sistemática en español e inglés, para establecer la máxima evidencia posible, con las indicaciones de la guía PRISMA. Dos artículos cumplieron con la calidad de la revisión. En el primero se estableció que el apiñamiento mejoro despues del tratamiento de expansion maxilar, con una recidiva menor en la dentición permanente. En el segundo, se encontró que el apiñamiento en los incisivos permanentes superiores fue corregido cuando se retiró el aparato expansor. Se concluyó que la evidencia actual no tiene la suficiente calidad metodológica para llevar a una toma de decisión. Se recomienda hacer ensayos clínicos aleatorizados en este tema.


ABSTRACT: Crowding at early ages is reflected when tooth size does not coincide with arch length. Thus, it is important to determine whether maxillary expansion alone could solve the problem of crowding in the anterior sector, bearing in mind that this treatment is one of the oldest and has commonly focused on solving transverse alterations in posterior teeth used at an early age. The objective was to determine whether or not maxillary expansion is effective in correcting crowding in the mixed dentition by analysing the available evidence. A systematic review was carried out in Spanish and English, to establish the maximum possible evidence, with the indications of the PRISMA guide. Two articles met the quality of the review. The first established that crowding improved after the treatment of maxillary expansion, with a minor recurrence in the permanent dentition. In the second, it was found that crowding in the upper permanent incisors was corrected when the expanding appliance was removed. The current evidence is not of sufficient methodological quality to lead to a decision. Randomized clinical trials are recommended in this area.

ABSTRACT

La técnica ortodóncica de baja fricción utiliza brackets pasivos de autoligado con una serie de arcos superelásticos que mantienen las fuerzas aplicadas sobre las piezas dentarias a nivel de la "biozona o zona fuerza óptima". La utilización de gomas intermaxilares ligeras (2 onzas o 56,68 g) en estos tratamientos, desde etapas iniciales, sobre todo en pacientes en crecimiento, permite obtener resultados muy favorables en cuanto a la resolución de la maloclusión de Clase II. Objetivo: evaluar el tratamiento de Ortodoncia de un paciente Clase II esqueletal con sobremordida, sin realizar exodoncias de premolares y utilizando elásticos intermaxilares en fases iniciales de tratamiento. Materiales y método: se presenta el caso clínico de un paciente de sexo masculino de 11 años, de Clase II esqueletal con sobremordida y apiñamiento dentario anterior superior e inferior moderado, con su diagnóstico y evaluación completos pre y post tratamiento y control y seguimiento al año. El tratamiento se realiza con brackets autoligantes (técnica de Damon). Resultados: se obtiene la corrección completa de la Clase II y la sobremordida, alcanzando los objetivos deseados de estética facial y función, en oclusión y desoclusiones, con buen desarrollo de las basales y conservación de la altura de las corticales alveolares a nivel de los caninos. Conclusión: Mediante los recursos terapéuticos disponibles en la actualidad y evaluando al niño en etapas tempranas, podremos combinar diferentes tratamientos para alcanzar los objetivos propuestos en menor tiempo y con óptimos resultados en una maloclusión de Clase II con sobremordida con biotipo mesofacial (AU)


The low friction orthodontic technique uses passive self-ligating brackets with a series of superelastic arches that maintain the forces applied to the dental pieces at the "Biozone or Optimal Force Zone". The use of inter maxillary light elastics (2 ounces or 56.68 yr.) from the initial stages in growing patients, yields very favorable results in terms of correction of Class II malocclusion. Objective: To assess the orthodontic treatment of a skeletal Class II patient with overbite, without extraction of premolars and using elastic in the early stages of treatment. Materials and methods: an 11 year old male skeletal Class II patient with overbite and moderate crowding in upper and lower anterior teeth, with complete diagnostic and evaluation before and after treatment and with annual control. For the treatment, self-ligating brackets (Damon technique) were employed. The results: Total correction of Class II condition and overbite was obtained. The desired goals of facial aesthetics and correct function were attained in occlusion and desocclusion, as well as development of the osseous basis and conservation of the canine alveolar cortical height. Conclusion: Through the employment of therapeutic resources available at present and following up the child through his developmental stages, it is possible to combine different treatments to achieve the proposed objectives in a shorter time with excellent results in mesofacial type patients with Class II malocclusion and deep overbite (AU)

ABSTRACT

Objetivo: El propósito de esta investigación es determinar el cambio de posición del cóndilo dentro de la cavidad glenoidea en pacientes clase II Esqueletal con mordida profunda después de la utilización de un plano de mordida anterior fijo acrílico y metálico. Materiales y Métodos: Se tomará una muestra del 20% de un universo de 100 pacientes de Clínica de la Escuela de Postgrado de la Facultad de Odontología de la Universidad de Guayaquil para demostrar los cambios que se producen en la articulación temporomandibular como consecuencia de la nueva posición adoptada por el cóndilo debido a la nueva postura mandibular por el uso del plano de mordida. Estos pacientes serán evaluados a través de radiografías cefalométricas que serán tomadas en el transcurso del uso de los planos de mordida anterior hasta el momento que se ha conseguido el contacto del segmento posterior de las piezas dentarias donde se tomará en consideración el cambio de posición del cóndilo y de esta manera determinar la estabilidad que se desea conseguir en el tratamiento. Resultados: Todos los pacientes que utilizaron plano de mordida anterior metálico obtuvieron en el 100% el cambio de posición del cóndilo mandibular, llegando a la norma de 32+-2; mientras que el 69,23% de los pacientes que utilizaron el plano de mordida anterior acrílico tuvieron un cambio positivo y el 30,77% fue negativo. Conclusiones: Por lo tanto se concluye que con el plano de mordida anterior metálico se obtiene mayor exactitud en el cambio de posición del cóndilo mandibular.


The purpose of this investigation is to determine the change of position of the condyle within the glenoid cavity in class II patients with deep bite after the use of a fixed anterior Acrylic and Metallic bite plane, which will be done with a sample of the 20% of a universe of 100 patients from Clinic of the Postgraduate School of the Faculty of Dentistry of the University of Guayaquil to demonstrate the changes that occur in the temporomandibular joint resulting from the new position adopted by the condyle due to the new mandibular posture by the use of the bite plane. These patients will be evaluated through cephalometric radiographs that will be taken in the course of the use of the anterior bite planes until the contact of the posterior segment of the dental pieces has been achieved where the change of position of the condyle will be taken into account And thus determine the stability to be achieved in the treatment. The results that presented the patients in the change of position of the mandibular condyle that they used plane of previous bite Metallic was positive in 100% of them, arriving at the norm of 32 + -2; While 69.23% of patients who used the anterior acrylic bite plane had a positive change and 30.77% were negative; Therefore it is concluded that with the Metallic anterior bite plane, greater accuracy is obtained in the position change of the mandibular condyle.

ABSTRACT

ABSTRACT Even though few technological advancements have occurred in Orthodontics recently, the search for more efficient treatments continues. This paper analyses how to accelerate and improve one of the most arduous phases of orthodontic treatment, i.e., correction of the curve of Spee. The leveling of a deep curve of Spee can happen simultaneously with the alignment phase through a method called Early Vertical Correction (EVC). This technique uses two cantilevers affixed to the initial flexible archwire. This paper describes the force system produced by EVC and how to control its side effects. The EVC can reduce treatment time in malocclusions with deep curves of Spee, by combining two phases of the therapy, which clinicians ordinarily pursue sequentially.


RESUMO Apesar de haver poucos desenvolvimentos tecnológicos nos últimos anos dentro da Ortodontia, a busca por tratamentos mais eficientes não cessou. Assim, o presente artigo visa analisar, de maneira lógica, como otimizar uma das fases do tratamento ortodôntico que mais demandam tempo: a correção da sobremordida exagerada. Pretende-se demonstrar como realizá-la concomitantemente ao alinhamento inicial, por meio de uma técnica denominada correção vertical precoce (CVP). Essa técnica utiliza dois cantilevers associados ao primeiro fio de alinhamento ortodôntico, mas não restritos a ele, a fim de iniciar a planificação da curva de Spee o mais cedo possível. Assim, o tempo de tratamento pode ser diminuído, já que duas fases do tratamento, normalmente realizadas de forma independente, podem ser realizadas ao mesmo tempo. Além disso, tanto o sistema de forças quanto os efeitos colaterais e os passos da execução da técnica serão devidamente apresentados e discutidos.

ABSTRACT

INTRODUCTION: Combined treatment offers advantages for partially edentulous patients. Conventional implants, used as orthodontic anchorage, enable previous orthodontic movement, which provides appropriate space gain for crown insertion. OBJECTIVE: This case report describes the treatment of a 61-year and 10-month-old patient with negative overjet which made ideal prosthetic rehabilitation impossible, thereby hindering dental and facial esthetics. CASE REPORT: After a diagnostic setup, conventional implants were placed in the upper arch to anchor intrusion and retract anterior teeth. Space gain for lateral incisors was achieved in the lower arch by means of an orthodontic appliance. CONCLUSIONS: Integrated planning combining Orthodontics and Implantology provided successful treatment by means of conventional implant-supported anchorage. The resulting occlusal relationship proved stable after 10 years. .


INTRODUÇÃO: tratamentos combinados podem oferecer vantagens em casos de edentulismo parcial. O uso de implantes convencionais como ancoragem ortodôntica permite a movimentação ortodôntica prévia, fornecendo os espaços apropriados para inserção das coroas. OBJETIVO: este relato de caso descreve o tratamento de uma paciente, com 61 anos e 10 meses de idade, que possuía um overjet negativo que tornava impossível uma reabilitação protética ideal, comprometendo a estética dentária e facial. RELATO DO CASO: após um setup diagnóstico, os implantes convencionais foram colocados na mandíbula para ancorar a intrusão e retração dos dentes anteriores. Espaços para os incisivos laterais foram abertos na maxila, usando-se aparelho ortodôntico. CONCLUSÕES: o planejamento integrado entre Ortodontia e Implantodontia propiciou um tratamento bem-sucedido, usando implantes convencionais como ancoragem. A relação oclusal obtida apresenta estabilidade 10 anos pós-tratamento. .

ABSTRACT

Anterior spaces may interfere with smile attractiveness and compromise dentofacial harmony. They are among the most frequent reasons why patients seek orthodontic treatment. However, midline diastema is commonly cited as a malocclusion with high relapse incidence by orthodontists. Objectives: This study aimed to evaluate the stability of maxillary interincisor diastemas closure and the association of their relapse and interincisor width, overjet, overbite and root parallelism. Material and Methods: Sample comprised 30 patients with at least a pretreatment midline diastema of 0.5 mm or greater after eruption of the maxillary permanent canines. Dental casts and panoramic radiographs were taken at pretreatment, posttreatment and postretention. Results: Before treatment, midline diastema width was 1.52 mm (SD=0.88) and right and left lateral diastema widths were 0.55 mm (SD=0.56) and 0.57 mm (SD=0.53), respectively. According to repeated measures analysis of variance, only midline diastema demonstrated significant relapse. In the overall sample the average relapse of midline diastema was 0.49 mm (SD=0.66), whilst the unstable patients showed a mean space reopening of 0.78 mm (SD=0.66). Diastema closure in the area between central and lateral incisors showed great stability. Multivariate correlation tests showed that only initial diastema width (β=0.60) and relapse of overjet (β=0.39) presented association with relapse of midline diastema. Conclusions: Midline diastema relapse was statistically significant and occurred in 60% of the sample, while lateral diastemas closure remained stable after treatment. Only initial diastema width and overjet relapse showed association with relapse of midline diastema. There was no association between relapse of interincisor diastema and root parallelism. .

ABSTRACT

Angle Class III malocclusion is characterized by an inadequate anteroposterior dental relationship which may or may not be accompanied by skeletal changes. In general, patients are distressed by a significantly compromised facial aspect which, when associated with a deficient middle third, encourages patients to seek treatment. This article reports a two-phase treatment carried out in a female patient aged six years and six months with a tendency towards a Class III skeletal pattern. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO). It is representative of the Discrepancy Index (DI) category, and fulfills part of the requirements for obtaining BBO Diploma.


A má oclusão de Classe III de Angle é caracterizada por uma relação dentária anteroposterior inadequada, que pode ou não estar acompanhada de alterações esqueléticas. Em geral, o aspecto facial fica bastante comprometido, principalmente quando associado à deficiência no terço médio, sendo esse, na maioria das vezes, o principal fator que motiva o paciente a procurar pelo tratamento ortodôntico. Este artigo relata o tratamento realizado em duas fases, de uma paciente do sexo feminino, com seis anos e seis meses de idade, com tendência a um padrão esquelético de Classe III. Este caso foi apresentado à diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO), representando a categoria com índice de grau de complexidade (IGC) igual ou acima de dez pontos, como parte dos requisitos para obtenção do título de Diplomada pelo BBO.

ABSTRACT

INTRODUCTION: The aim of this retrospective study was to compare the occlusal outcomes, duration and efficiency of Class I malocclusion treatment carried out with and without premolar extractions in patients with different degrees of initial malocclusion severity. METHODS: Complete records of 111 patients were obtained and divided into two groups: Group 1 consisted of 65 patients at an initial mean age of 13.82 years old treated with four premolar extractions; whereas Group 2 consisted of 46 patients at an initial mean age of 14.01 years old treated without extractions. Two subgroups were obtained from each group (1A, 1B, 2A and 2B) with different degrees of malocclusion severity according to the initial values of PAR index. Compatibility was assessed using chi-square and t-tests. The subgroups were compared by means of Analysis of Variance (ANOVA).The variables that might be related to treatment duration and efficiency were assessed using the multiple linear regression analysis. RESULTS: Initial malocclusion severity was positively related to the amount of occlusal correction and consequently to a higher efficiency index. Moreover, extraction protocol showed a positive relationship with treatment duration and a negative relationship with treatment efficiency. CONCLUSION: Extraction and non-extraction protocols for correction of Class I malocclusion provide similar satisfactory results; however, the extraction protocol increases the overall treatment duration. Orthodontic treatment is more efficient in cases with high initial malocclusion severity treated with a non-extraction protocol. .


INTRODUÇÃO: o objetivo desse estudo retrospectivo foi comparar os resultados oclusais, o tempo e o grau de eficiência do tratamento da má oclusão de Classe I realizado com e sem extrações em pacientes que apresentavam diferentes tipos de severidade oclusal inicial. MÉTODOS: a amostra foi composta pelas documentações de 111 pacientes, divididas em dois grupos: Grupo 1 (n = 65), com idade inicial média de 13,82 anos, tratados com extrações; Grupo 2 (n = 46), com idade inicial média de 14,01 anos, tratados sem extrações. De cada grupo, foram obtidos dois subgrupos (1A, 1B, 2A e 2B) com severidades oclusais diferentes (alta e baixa), de acordo aos valores iniciais do índice PAR. A avaliação da compatibilidade foi realizada por meio do teste qui-quadrado e do teste t. Os subgrupos foram comparados por meio da análise de variância (ANOVA) e foi realizada a análise de regressão linear múltipla para avaliação das variáveis que poderiam estar relacionadas com o tempo e com a eficiência do tratamento. RESULTADOS: a severidade oclusal inicial esteve diretamente relacionada à quantidade de sua correção e, consequentemente, à obtenção de um maior índice de eficiência; por outro lado, a utilização do protocolo de extrações de pré-molares mostrou uma relação direta com o tempo de tratamento e inversa com a eficiência do tratamento. CONCLUSÃO: no tratamento da má oclusão de Classe I, podem ser obtidos resultados oclusais satisfatórios com uma maior quantidade de correção das alterações oclusais nos casos com maior severidade inicial, e um maior tempo de tratamento quando o tratamento envolve extrações dentárias. .

ABSTRACT

INTRODUCTION: Orthodontics, just as any other science, has undergone advances in technology that aim at improving treatment efficacy with a view to reducing treatment time, providing patients with comfort, and achieving the expected, yet hardly attained long-term stability. The current advances in orthodontic technology seem to represent a period of transition between conventional brackets (with elastic ligatures) and self-ligating brackets systems. Scientific evidence does not always confirm the clear clinical advantages of the self-ligating system, particularly with regard to reduced time required for alignment and leveling (a relatively simple protocol), greater comfort for patients, and higher chances of performing treatment without extractions - even though the number of extractions is more closely related to patient's facial morphological pattern, regardless of the technique of choice. Orthodontics has recently and brilliantly used bracket individualization in compensatory treatment with a view to improving treatment efficacy with lower biological costs and reduced treatment time. OBJECTIVE: This paper aims at presenting a well-defined protocol employed to produce a better treatment performance during this period of technological transition. It explores the advantages of each system, particularly with regards to reduced treatment time and increased compensatory tooth movement in adult patients. It particularly addresses compensable Class III malocclusions, comparing the system of self-ligating brackets, with which greater expansive and protrusive tooth movement (maxillary arch) is expected, with conventional brackets Capelozza Prescription III, with which maintaining the original form of the arch (mandibular arch) with as little changes as possible is key to yield the desired results. .


INTRODUÇÃO: a Ortodontia passa, como toda ciência, por constantes evoluções tecnológicas que buscam aumentar a efetividade da abordagem terapêutica, visando a diminuição do tempo de tratamento, o aumento do conforto para os pacientes, bem como a obtenção da tão almejada, e pouco alcançada, estabilidade em longo prazo. O estágio atual de desenvolvimento tecnológico da Ortodontia representa, ao que tudo indica, uma fase de transição entre os sistemas convencionais de ligação (com módulos elásticos) e os chamados autoligáveis. As evidências científicas nem sempre consubstanciam a clara percepção clínica das vantagens desse sistema, no que diz respeito a um menor tempo de alinhamento e nivelamento, uma relativa simplificação técnica, maior conforto para os pacientes, além do aumento da capacidade de tratamento sem extrações - embora essa indicação esteja mais ligada à avaliação do padrão morfológico facial, e menos a qualquer escolha técnica. Desde um passado recente e não menos brilhante, a Ortodontia vem utilizando a individualização de braquetes para tratamentos compensatórios, buscando aumentar a efetividade da abordagem terapêutica, com menores custos biológicos e menor tempo de tratamento. OBJETIVO: o presente artigo tem como objetivo apresentar um protocolo bem definido de melhor aproveitamento dessa fase de transição tecnológica, buscando explorar o que cada sistema tem de melhor, principalmente sob a óptica da redução do tempo de tratamento e aumento da capacidade de movimentação dentária compensatória em pacientes adultos. Especificamente, serão abordadas as más oclusões de Classe III compensáveis, usando o sistema de braquetes ...

ABSTRACT

OBJECTIVE: The aim of this study was to cephalometrically assess the skeletal and dentoalveolar effects of Class II malocclusion treatment performed with the Jones Jig appliance followed by fixed appliances. METHODS: The sample comprised 25 patients with Class II malocclusion treated with the Jones Jig appliance followed by fixed appliances, at a mean initial age of 12.90 years old. The mean time of the entire orthodontic treatment was 3.89 years. The distalization phase lasted for 0.85 years, after which the fixed appliance was used for 3.04 years. Cephalograms were used at initial (T1), post-distalization (T2) and final phases of treatment (T3). For intragroup comparison of the three phases evaluated, dependent ANOVA and Tukey tests were used. RESULTS: Jones Jig appliance did not interfere in the maxillary and mandibular component and did not change maxillomandibular relationship. Jones Jig appliance promoted distalization of first molars with anchorage loss, mesialization and significant extrusion of first and second premolars, as well as a significant increase in anterior face height at the end of treatment. The majority of adverse effects that occur during intraoral distalization are subsequently corrected during corrective mechanics. Buccal inclination and protrusion of mandibular incisors were identified. By the end of treatment, correction of overjet and overbite was observed. CONCLUSIONS: Jones Jig appliance promoted distalization of first molars with anchorage loss represented by significant mesial movement and extrusion of first and second premolars, in addition to a significant increase in anterior face height. .


OBJETIVO: a proposta desse estudo foi avaliar cefalometricamente os efeitos esqueléticos e dentoalveolares do tratamento da má oclusão de Classe II com o distalizador Jones jig, seguido do uso do aparelho fixo corretivo. MÉTODOS: a amostra constituiu de 25 pacientes com má oclusão de Classe II, tratados com o distalizador Jones Jig, seguido do uso de aparelho fixo corretivo, com média de idade inicial de 12,90 anos. O tempo médio de tratamento ortodôntico total foi de 3,89 anos. A fase de distalização durou 0,85 anos, e a fase de aparelho fixo pós-distalização foi de 3,04 anos. Foram utilizadas as telerradiografias nos tempos inicial (T1), pós-distalização (T2) e final do aparelho fixo (T3). Para comparação intragrupo nos três tempos avaliados, foram utilizados os testes ANOVA dependente e de Tukey. RESULTADOS: os resultados demonstraram que o Jones Jig não interferiu no componente maxilar e mandibular, e não promoveu alterações na relação maxilomandibular. O Jones Jig promoveu distalização dos primeiros molares, com perda de ancoragem, mesialização e extrusão significativa dos primeiros e segundos pré-molares, e aumento significativo da altura facial anteroinferior ao final do tratamento. A maioria dos efeitos adversos ocorridos na fase de distalização intrabucal são posteriormente corrigidos durante a mecânica corretiva. Verificou-se vestibularização e protrusão dos incisivos inferiores. Ao final do tratamento, foi observada a correção dos trespasses horizontal e vertical. CONCLUSÕES: o distalizador Jones Jig promoveu a distalização dos primeiros molares, com perda de ancoragem, representada pela mesialização e extrusão significativa dos primeiros e segundos pré-molares, e aumento significativo ...

ABSTRACT

Angle Class I malocclusion with bimaxillary protrusion is characterized by severe buccal tipping of incisors, which causes upper and lower lip protrusion. First premolars extraction is recommended to reduce facial convexity as a result of anterior teeth retraction, which keeps canines and first molars in key to occlusion. In order to yield orthodontic results that are compatible with ideal esthetic and cephalometric outcomes, the space closure phase needs to be carried out with overbite and incisors torque control. The majority of cases also requires maximum anchorage of posterior teeth. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) as a requirement for the title of certified by the BBO.


A má oclusão de Classe I de Angle com biprotrusão é caracterizada pela inclinação acentuada dos incisivos para vestibular, o que provoca a protrusão dos lábios superior e inferior. As extrações dos primeiros pré-molares têm sido indicadas para reduzir a convexidade facial com a retração dos dentes anteriores, mantendo a relação de chave de oclusão dos caninos e dos primeiros molares. Para a obtenção de resultados compatíveis com as metas estéticas e cefalométricas idealizadas para o tratamento ortodôntico, é necessário que a fase de fechamento de espaços seja realizada com controle da sobremordida e do torque dos incisivos. Na maioria dos casos, também há necessidade de se proporcionar ancoragem máxima aos dentes posteriores. O presente caso clínico foi apresentado à Diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO) como parte dos requisitos para a obtenção do título de Diplomado pelo BBO.

ABSTRACT

OBJECTIVE: To assess skeletal and dental changes immediately after rapid maxillary expansion (RME) in Class II Division 1 malocclusion patients and after a retention period, using cone beam computed tomography (CBCT) imaging. METHODS: Seventeen children with Class II, Division 1 malocclusion and maxillary skeletal transverse deficiency underwent RME following the Haas protocol. CBCT were taken before treatment (T1), at the end of the active expansion phase (T2) and after a retention period of 6 months (T3). The scanned images were measured anteroposteriorly (SNA, SNB, ANB, overjet and MR) and vertically (N-ANS, ANS-Me, N-Me and overbite). RESULTS: Significant differences were identified immediately after RME as the maxilla moved forward, the mandible moved downward, overjet increased and overbite decreased. During the retention period, the maxilla relapsed backwards and the mandible was displaced forward, leaving patients with an overall increase in anterior facial height. CONCLUSION: RME treatment allowed more anterior than inferior positioning of the mandible during the retention period, thus significantly improving Class II dental relationship in 75% of the patients evaluated. .


OBJETIVO: avaliar, por meio de imagens de tomografia computadorizada de feixe cônico (TCFC), as mudanças esqueléticas e dentárias, imediatas e após 6 meses de contenção, causadas pela expansão rápida da maxila (ERM) em pacientes com má oclusão de Classe II, divisão 1. MÉTODOS: dezessete crianças com má oclusão de Classe II, divisão 1, e deficiência transversal da maxila, foram submetidas a ERM, de acordo com o protocolo proposto por Haas. TCFC foram realizadas antes da ERM (T1), imediatamente após a fase ativa (T2) e após 6 meses de contenção (T3). Alterações anteroposteriores (SNA, SNB, ANB, overjet e RM) e verticais (N-ANS, ANS-Me, N-Me e overbite) foram analisadas. RESULTADOS: imediatamente após a ERM, enquanto a maxila se deslocou para frente, a mandíbula se movimentou para frente e para baixo, aumentando o overjet e diminuindo o overbite. Durante o período de contenção, a maxila retornou para posterior e a mandíbula deslocou em direção anterior, aumentando a altura facial anterior. CONCLUSÃO: a realização da ERM permitiu que a mandíbula se posicionasse mais anteriormente do que inferior durante o período de contenção, melhorando a relação molar de Classe II em 75% dos pacientes avaliados. .
