ABSTRACT

Resumo O tratamento com alinhadores ortodônticos já uma realidade na prática ortodôntica, em especial para casos de baixa complexidade. Em muitos desses casos, a falta de espaço, caracterizada pelo apinhamento, faz parte do problema. Assim, com intuito de prover espaços, dentre inúmeros recursos existentes, pode-se também considerar o desgaste interproximal, a depender de cada caso. Com a finalidade de reduzir o diâmetro mesiodistal dos dentes, os desgastes interproximais precisam ser feitos de forma criteriosa. O objetivo desse artigo é apresentar um protocolo seguro de desgastes interproximais considerando diferentes situações cínicas. (AU)


Abstract Treatment with orthodontic aligners is already a reality in orthodontic practice, especially for low complexity cases. In many of these patients, the lack of space, characterized by crowding, is part of the problem. Thus, in order to provide spaces, among numerous available resources, interproximal reduction may be considered, depending on each case. In order to shorten mesiodistal teeth width, interproximal reduction should be done carefully. This paper aims to present a reliable protocol for interproximal reduction considering different clinical situations. (AU)

ABSTRACT

O correto posicionamento dos acessórios ortodônticos é de suma importância para uma boa finalização. Com o uso da tecnologia CAD-CAM na Ortodontia, hoje é possível posicionar os acessórios virtualmente e avaliar a repercussão desse posicionamento após o alinhamento e nivelamento dos dentes. Com os acessórios colados na posição desejada, é confeccionada uma guia de transferência virtual e, em seguida, impressa por meio de uma impressora 3D. Dessa forma, é possível minimizar erros, o que demandaria maior necessidade de confecção de dobras nos fios e maior tempo de tratamento. A proposta desse artigo é, por meio de um caso clínico, apresentar um protocolo laboratorial e clínico de colagem indireta virtual. (AU)


Correct brackets positioning is very important for appropriate finishing. The use of CAD/CAM technology in Dentistry today allows brackets virtual positioning and assessment of this position after teeth alignment and leveling. Brackets can therefore be positioned according to their final estimated position. When brackets are bonded in the desired position, a virtual transfer guide is created, and 3D printed. Thus, it is possible to minimize errors, which would require bends in the wires and possibly increase treatment time. The aim of this paper is to describe a clinical case, presenting laboratorial and clinical protocol of a virtual indirect bonding. (AU)

ABSTRACT

Resumo O tratamento ortodôntico com alinhadores é algo desejado cada vez mais pelos pacientes. Sabe-se que esses dispositivos carregam consigo vantagens e desvantagens quando comparados ao aparelho fixo convencional. Em uma tentativa de potencializar os movimentos planejados virtualmente, na grande maioria dos casos attachments são necessários. Nesse sentido, é de suma importância um protocolo seguro de instalação dos attachments, conferindo assim uma maior estabilidade e estética desses. O objetivo deste artigo é descrever o momento de instalação dos attachments em uma paciente, destacando os materiais utilizados (AU)


Abstract Today, many patients demand orthodontic treatment using aligners. It is widely known that that these devices have both advantages and disadvantages compared to conventional brackets. In order to produce better results attachments are generally needed to accomplish most dental movements. Thus, it is of upmost importance to have a safe and sound protocol to install attachments. This allows greater stability to their bonding and adequate esthetics to the patient. The aim of this clinical report is to describe how to add attachments to a patient, depicting all the materials needed for that purpose (AU)

ABSTRACT

INTRODUCTION: In this study, we aimed at evaluating the maturation stage of the midpalatal suture based on its morphology, using cone-beam computed tomography images in young postadolescents. METHODS: The sample comprised 112 patients, 68 female and 44 male, aged 16 to 20 years, consecutively selected from 2 private orthodontic clinics. They had cone-beam computed tomography images in their initial orthodontic files, requested for orthodontic planning purposes. These images were exported to the Invivo 5 program (Anatomage, San Jose, Calif), where axial sections were obtained from the midpalatal suture for morphologic evaluation. Two previously calibrated examiners interpreted the images to establish the stage of sutural maturation of each patient according to its morphologic characteristics in 5 maturational stages (A, B, C, D, and E). The kappa coefficient was applied for intraexaminer and interexaminer agreements, and their values were 0.87 and 0.89, respectively. RESULTS: The maturational stages most often observed in this study were C, D, and E, (91.9%). In males, stage C was present in 52.3%; for females this prevalence was 39.7%. CONCLUSIONS: The high prevalence of stage C in this age group may justify a clinical study to confirm the good prognosis for rapid maxillary expansion in postadolescents.

ABSTRACT

Pattern II may require different therapeutic approaches. When the face is at least acceptable, treatment may be restricted to dentoalveolar region. However, when the is unpleasant, correction should involve performing orthognathic surgery, in addition to the orthodontic treatment. And that is exactly the synergic union of all specialties - Implant, prosthesis, surgery and orthodontics - which ensures the construction of a more aesthetic and healthy smile and with significant face improvements. The aim of this study is to describe a case of an adult patient, black, malocclusions class II, severe mandibular deficiency, unpleasant face. The treatment involved descompensatory orthodontics, prosthetic rehabilitation, orthognathic surgery and finally aesthetic reanatomization the upper front teeth, which allowed the patient a normality condition of occlusion and face.(AU)


As más oclusões do Padrão II podem demandar diferentes abordagens terapêuticas. Quando a face é no mínimo aceitável, o tratamento poderá se restringir a região dentoalveolar. No entanto, quando a face é desagradável a correção deve envolver a realização de cirurgia ortognática, além do tratamento ortodôntico. E é exatamente à união sinérgica de todas as especialidades - Implante, Prótese, Cirurgia e Ortodontia ­ que garante a construção de um sorriso mais estético e saudável e com melhorias significativas na face. O objetivo desse trabalho é descrever um caso clínico de um paciente adulto, negro, Padrão II, deficiência mandibular grave, face desagradável. O tratamento envolveu ortodontia descompensatória, reabilitação protética, cirurgia ortognática e por fim, reanatomização estética dos dentes anteriores superiores, o que permitiu ao paciente uma condição de normalidade oclusal e facial.

ABSTRACT

INTRODUCTION: We used cone-beam computed tomography to evaluate the maturation stages of the midpalatal sutures in children aged 11 to 15 years old. Maxillary expansion is successful for most patients in this age group, so we sought to identify the status of suture maturation in these subjects to use as a comparison for the prognosis of rapid maxillary expansion in older patients. METHODS: Tomographic images in axial sections of the midpalatal sutures from 84 children (40 boys, 44 girls; ages, 11-15 years) were classified using a scale denoting the maturation stage of the midpalatal suture (A, B, C, D, and E). The chi-square test was applied to evaluate suture stages by sex and age groups. RESULTS: Stage A was observed in only one 11-year-old girl. Stage B was present at all ages but was more prevalent in those less than 13 years of age. Stage C was the most prevalent in all evaluated ages. Stages D and E showed low prevalence rates. There were higher prevalences of the early stages of maturation in boys. CONCLUSIONS: The results of this study, which showed dominant prevalence of stage C, suggest that conventional, nonsurgical rapid maxillary expansion performed in patients over 15 years old is justified by a satisfactory prognosis when assessment of the sutural status indicates stage C.

ABSTRACT

Introdução: O objetivo deste trabalho é apresentar, por meio da análise de um caso clínico, um protocolo para diagnóstico e tratamento de pacientes portadores de deformidade dentofacial, candidatos ao tratamento ortodôntico-cirúrgico. Esse tratamento exige cautelosa análise da estética facial, da oclusão e do padrão respiratório do paciente. Um diagnóstico preciso é fundamental para a construção de um plano de tratamento adequado, elaborado conjuntamente por cirurgiões e ortodontistas. Os avanços nos exames de imagens 3D na última década permitiram um aumento sem precedentes da precisão no diagnóstico e na execução do planejamento cirúrgico. Atualmente, o planejamento virtual constitui uma importante ferramenta para a realização do tratamento orto-cirúrgico. A cirurgia virtual possui maior precisão, melhorando a capacidade de reprodução do plano de tratamento na sala de cirurgia. Entretanto, é importante que protocolos para o tratamento virtual sejam estabelecidos e aprimorados

ABSTRACT

The aim of this clinical report is to describe the complex treatment of an adult Class III malocclusion patient who was disappointed with the outcome of a previous oral rehabilitation. Interdisciplinary treatment planning was performed with a primary indication for implant removal because of marginal bone loss and gingival recession, followed by orthodontic and surgical procedures to correct the esthetics and skeletal malocclusion. The comprehensive treatment approach included: (1) implant removal in the area of the central incisors; (2) combined orthodontic decompensation with mesial displacement and forced extrusion of the lateral incisors; (3) extraction of the lateral incisors and placement of new implants corresponding to the central incisors, which received provisional crowns; (4) orthognathic surgery for maxillary advancement to improve occlusal and facial relationships; and finally, (5) orthodontic refinement followed by definitive prosthetic rehabilitation of the maxillary central incisors and reshaping of the adjacent teeth. At the three-year follow-up, clinical and radiographic examinations showed successful replacement of the central incisors and improved skeletal and esthetic appearances. Moreover, a Class II molar relationship was obtained with an ideal overbite, overjet, and intercuspation. In conclusion, we report the successful esthetic anterior rehabilitation of a complex case in which interdisciplinary treatment planning improved facial harmony, provided gingival architecture with sufficient width and thickness, and improved smile esthetics, resulting in enhanced patient comfort and satisfaction. This clinical case report might be useful to improve facial esthetics and occlusion in patients with dentoalveolar and skeletal defects.

ABSTRACT

Consistently performed by most orthodontists, the orthopedic treatment involves rapid maxillary expansion (RME) combined with maxillary protraction (MP). When this treatment protocol is performed up to the intertransitional period of the mixed dentition (around 9 years of age), it allows a positive influence on the maxilla and zygomatic projection, even though there are also effects on the dentition. The ideal orthopedic treatment should influence the growth and spatial arrangement of bone bases (maxilla and mandible), so as to achieve balance and maintain it until growth completion. This goal may seem utopic, especially when the problem involves the mandible; and, assuming some genetic influence for such disorder, it is difficult to predict its future magnification during the growth period. Notwithstanding, despite the uncertain prognosis, the search for function and better facial esthetics, though temporary, should be considered This paper discusses this topic, based on the treatment progress of a youngpatient with Class III, with monitoring ofgrowth from the deciduous dentition up to adulthood, and treatment performed in two periods, using the RME and MPprotocol. Positive outcomes were achieved.

ABSTRACT

INTRODUCTION: Cone-Beam Computed Tomography (CBCT) is essential for tridimensional planning of orthognathic surgery, as it allows visualization and evaluation of bone structures and mineralized tissues. Tomographic slices allow evaluation of tooth inclination and individualization of movement performed during preoperative decompensation. The aim of this paper was to assess maxillary and mandibular incisors inclination pre and post orthodontic decompensation in skeletal Class III malocclusion. METHODS: The study was conducted on six individuals with skeletal Class III malocclusion, surgically treated, who had Cone-Beam Computed Tomographic scans obtained before and after orthodontic decompensation. On multiplanar reconstruction view, tomographic slices (axial, coronal and sagittal) were obtained on the long axis of each incisor. The sagittal slice was used for measurement taking, whereas the references used to assess tooth inclination were the long axis of maxillary teeth in relation to the palatal plane and the long axis of mandibular teeth in relation to the mandibular plane. RESULTS: There was significant variation in the inclination of incisors before and after orthodontic decompensation. This change was of greater magnitude in the mandibular arch, evidencing that natural compensation is more effective in this arch, thereby requiring more intensive decompensation. CONCLUSION: When routinely performed, the protocols of decompensation treatment in surgical individuals often result in intensive movements, which should be reevaluated, since the extent of movement predisposes to reduction in bone attachment levels and root length.

Introdução: a tomografia computadorizada de feixe cônico (TCFC) é essencial para o planejamento tridimensional de cirurgias ortognáticas, pois permite a visualização e avaliação de estruturas ósseas e tecidos mineralizados. Os cortes tomográficos permitem avaliar a inclinação dos dentes e individualizar o movimento realizado durante a descompensação dentária.Objetivo: o objetivo do presente estudo foi avaliar a inclinação dos incisivos superiores e inferiores antes e depois da descompensação ortodôntica da má oclusão de Classe III esquelética.Métodos:o estudo foi realizado em seis indivíduos com má oclusão de Classe III esquelética que passaram por tratamento cirúrgico e apresentaram exames de TCFC feitos antes e depois da descompensação ortodôntica. A reconstrução multiplanar foi feita a partir dos cortes tomográficos (axial, coronal e sagital) adquiridos no eixo longitudinal de cada incisivo. O corte sagital foi usado para a realização de medições, e as referências usadas para avaliar a inclinação dentária foram o eixo longitudinal dos dentes superiores em relação ao plano palatino e o eixo longitudinal dos dentes inferiores em relação ao plano mandibular.Resultados:houve uma variação significativa entre a inclinação dos incisivos antes e depois da descompensação ortodôntica. A alteração foi maior na arcada inferior, evidenciando que a compensação natural é mais efetiva nessa arcada, o que exige uma descompensação mais extensa.Conclusão:quando realizados rotineiramente, os protocolos de tratamento para descompensação em pacientes cirúrgicos geralmente resultam em movimentação extensa, que deve ser reavaliada, já que a extensão do movimento predispõe à perda de inserção e à redução do comprimento da raiz.

ABSTRACT

Controlling the eruption and development of dentitions is fundamental for a good oral health. The early diagnosis and adequate treatment of occasional developmental disorders are essential to achieve occlusal, functional and esthetic harmony. Abnormality is the term used for classification of alterations and is the most common developmental anomaly in humans. Even though several factors causing tooth malformations have been identified, many are still partially understood, thus requiring a more thorough study. Anyway, the available knowledge provides bases to attempt the early diagnosis of tooth abnormalities, to allow the adoption of preventive and effective therapeutic approaches.

ABSTRACT

There has always been concern in determining the relationship between orthodontic tooth movement and the consequent biological costs to the periodontium and tooth root. The possibility of evaluating the tooth and bone morphology by CBCT allows more accurate analysis of qualitative and quantitative aspects of these processes. This paper presents a case report of a 20-year-old male patient with Class III malocclusion and hyperdivergent facial pattern, who was surgically treated. A significant amount of labial movement of mandibular incisors was performed during orthodontic treatment before surgery. CBCT was used for evaluation of buccal and lingual bone plates before and after tooth decompensation. The changes in the bone insertion level of maxillary and mandibular incisors in the present case encourage a reflection on the treatment protocol in individuals with dentoskeletal discrepancies.

ABSTRACT

The contemporary orthodontics should highlight the periodical control of growth and dental development in order to intercept possible disorders in facial growth and tooth eruption. This may allow avoidance or simplification of corrective orthodontic treatment, making it faster and less aggressive. Tooth transposition, a genetically determined eruptive disturbance, presents a relatively low prevalence in the world population and primarily affects maxillary canines and premolars. This paper presents an option for interceptive treatment of bilateral transposition of maxillary canine and premolar diagnosed early in a young individual. Longitudinal follow-up of RME performed in adequate timing to redirect the eruption pathway of permanent maxillary canines is presented.

ABSTRACT

O programa de extrações seriadas (PES) é baseado na extração de dentes, inicialmente decíduos, e, então, permanentes, em pacientes com relação oclusal de Classe I que apresentam discrepância de modelo negativa grave. O tratamento tem início na dentição mista, com a extração de molares ou, até mesmo, de caninos decíduos, e, posteriormente, a extração dos primeiros pré-molares, na dentição permanente. A sequência das extrações pode sofrer algumas variações e demanda um longo período de acompanhamento entre as fases do tratamento, até que o programa de extrações seja finalizado e o paciente esteja apto para a fase corretiva. O presente artigo tem como objetivo apresentar, por meio de um caso clínico, o tratamento de uma paciente Padrão Face Longa subtipo médio, que foi submetida ao PES e, em seguida, ao tratamento ortodôntico compensatório

ABSTRACT

A prática da Odontologia de acompanhamento, de modo contemporâneo, exige dos ortodontistas conhecimento para controlar a erupção e o desenvolvimento da dentição, considerando o padrão de crescimento. Atualmente, pacientes procuram orientação ortodôntica cada vez mais cedo, dando a devida importância ao diagnóstico precoce de uma possível doença (má oclusão). De modo geral, e desde há muito tempo, a atenção primordial da prática ortodôntica foi à fase ativa do tratamento, em geral realizada com aparelho fixo. No contexto cultural em que está inserida a maior parte dos pacientes ortodônticos, não parece adequado continuar com esse foco. A busca pela saúde positiva, ou algo a mais que a simples ausência de doença, torna oportunos estudos relacionados à metas terapêuticas preventivas individualizadas e planos de tratamentos customizados. O presente artigo tem por objetivo ilustrar, por essa perspectiva, o caso clínico de um paciente Padrão Face Longa que foi acompanhado desde os 7 anos de idade e que possibilitou a atuação do profissional em duas fases, sempre considerando o prognóstico e a melhor época para tratamento dos problemas envolvidos.

ABSTRACT

O aumento do número de pacientes adultos buscando tratamento ortodôntico exigiu mudanças nos protocolos de tratamento. O desenvolvimento de novas modalidades terapêuticas, como os dispositivos de ancoragem absoluta, permite ao profissional resultados previsíveis nos casos de recuperação de espaço para reabilitação protética de dentes perdidos. A perda de um dente na região posterior prejudica a função mastigatória do lado envolvido. Além disso, essa ausência dentária propicia o movimento de sobre-erupção dos dentes antagonistas, agravando o desarranjo oclusal. O presente artigo apresenta um caso clínico onde foi realizada intrusão de primeiro e segundo molar superior direito, por meio de cadeia elástica apoiada em mini-implantes instalados por vestibular e por palatina, promovendo o nivelamento dentário desta região e permitindo a reabilitação protética dos dentes inferiores perdidos.


The increasing number of adult patients seeking for orthodontic treatment has demanded modifications in treatment protocols. The development of new therapeutic modalities, such as absolute anchorage devices, allows predictable results in cases of space recovery for prosthetic rehabilitation of missing teeth. The loss of a posterior tooth impairs masticatory function of the involved site. In addition the absence of a tooth propitiates over eruption of antagonist teeth, aggravating occlusal derangement. This article presents a case report of intrusion of maxillary first and second right molars using elastic chain supported by mini-implants placed vestibular and palatal, promoting dental leveling and allowing prosthetic rehabilitation of absent mandibular teeth.

ABSTRACT

No caso de pacientes com deformidades dentoesqueléticas, a agradabilidade facial é o fator primário que irá determinar se o tratamento será de caráter compensatório ou cirúrgico. Portanto, o diagnóstico deverá priorizar a face, identificando a localização e gravidade do problema, de acordo com o sexo, idade e etnia. Sendo assim, o tratamento ortodôntico cirúrgico das más oclusões do Padrão Face Longa tem como objetivo corrigir não somente a oclusão, mas especialmente o erro facial. A ação descompensatória exige uma atenção maior no planejamento de movimentações vestibulolinguais dos dentes anteriores superiores e inferiores, pois esses exibem uma relação exígua com suas respectivas bases ósseas. Esse artigo tem por objetivo ilustrar, por meio de um caso clínico, essa perspectiva de tratamento, onde a Ortodontia descompensatória eliminou a excrescência dentária localizada e a essência do problema — o erro esquelético — foi corrigida por meio de cirurgia ortognática.

ABSTRACT

O tratamento ortodôntico compensatório das más oclusões do Padrão III pode ser adotado quando a face do paciente apresenta características aceitáveis. O protocolo de tratamento para esses pacientes tem como objetivo melhorar as relações dentárias, removendo as excrescências e manter as relações faciais. O presente trabalho objetiva ilustrar, por meio de um caso clínico, a sequência de tratamento ortodôntico compensatório de um paciente do gênero masculino, com idade de 18 anos e 5 meses, Padrão III, que apresentava má oclusão de Classe III, caracterizada pela deficiência maxilar moderada, sendo que o tratamento foi finalizado em 18 meses com a correção da relação oclusal.


The compensatory orthodontic treatment of Pattern III malocclusions may be adopted when the facial features of the patient is esthetically acceptable. The objective of this treatment perspective is essentially to improve the dental relations, removing the excrescenses, and maintaining the facial relationships. The present paper aims to illustrate, through a clinical case, a therapeutic sequence of compensatory orthodontic treatment of a young male adult Pattern III patient, showing moderate maxilla deficiency. The treatment time persisted for 18 months to reach the proper oclusal relationship.
