ABSTRACT

Abstract Objective The aim of this retrospective study was to evaluate the long-term effects of orthodontic traction on root length and alveolar bone level in impacted canines and adjacent teeth. Material and Methods Sample consisted of 16 patients (nine males and seven females), mean initial age 11 years and 8 months presenting with unilaterally maxillary impacted canines, palatally displaced, treated with the same surgical and orthodontic approach. Teeth from the impacted-canine side were assigned as Group I (GI), and contralateral teeth as control, Group II (GII). The mean age of patients at the end of orthodontic treatment was 14 years and 2 months and the mean post-treatment time was 5 years and 11 months. Both contralateral erupted maxillary canines and adjacent teeth served as control. Root length and alveolar bone level (buccal and palatal) were evaluated on cone-beam computed tomography (CBCT) images. The comparison of root length and alveolar bone level changes between groups were assessed by applying paired t-test, at a significance level of 5% (p<0.05). Results There were no statistically significant differences in root length and buccal and palatal bone levels of canines and adjacent teeth among groups. Conclusions Impacted canine treatment by closed-eruption technique associated with canine crown perforation, has a minimal effect on root length and buccal and palatal alveolar bone level in both canine and adjacent teeth, demonstrating that this treatment protocol has a good long-term prognosis.

ABSTRACT

Objective: This study aimed at assessing the relationship between facial morphological patterns (I, II, III, Long Face and Short Face) as well as facial types (brachyfacial, mesofacial and dolichofacial) and obstructive sleep apnea (OSA) in patients attending a center specialized in sleep disorders. Methods: Frontal, lateral and smile photographs of 252 patients (157 men and 95 women), randomly selected from a polysomnography clinic, with mean age of 40.62 years, were evaluated. In order to obtain diagnosis of facial morphology, the sample was sent to three professors of Orthodontics trained to classify patients' face according to five patterns, as follows: 1) Pattern I; 2) Pattern II; 3) Pattern III; 4) Long facial pattern; 5) Short facial pattern. Intraexaminer agreement was assessed by means of Kappa index. The professors ranked patients' facial type based on a facial index that considers the proportion between facial width and height. Results: The multiple linear regression model evinced that, when compared to Pattern I, Pattern II had the apnea and hypopnea index (AHI) worsened in 6.98 episodes. However, when Pattern II was compared to Pattern III patients, the index for the latter was 11.45 episodes lower. As for the facial type, brachyfacial patients had a mean AHI of 22.34, while dolichofacial patients had a significantly statistical lower index of 10.52. Conclusion: Patients' facial morphology influences OSA. Pattern II and brachyfacial patients had greater AHI, while Pattern III patients showed a lower index.


Objetivo: o objetivo deste estudo foi avaliar a associação entre os padrões morfológicos faciais e tipos faciais (braquifacial, mesofacial e dolicofacial) com a Apneia Obstrutiva do Sono (AOS) em pacientes de um centro especializado em distúrbios do sono. Métodos: foram utilizadas fotografias faciais de frente, perfil e sorriso de 252 indivíduos, selecionados aleatoriamente entre pacientes que procuraram uma clínica especializada em polissonografia. Para o diagnóstico morfológico facial, a amostra foi enviada a três professores de Ortodontia treinados na classificação do padrão facial, e cada um recebeu a orientação para classificar o padrão facial da seguinte forma: 1 = Padrão I, 2 = Padrão II, 3 = Padrão III, 4 = Padrão Face Longa e 5 = Padrão Face Curta. A concordância interexaminadores foi avaliada por meio do Índice Kappa. O diagnóstico do tipo facial foi estabelecido por meio de um índice facial que leva em consideração a proporção entre a largura e altura da face. Resultados: no modelo de regressão linear múltipla, ficou evidenciado que o Padrão II teve a capacidade de agravar o índice de apneia e hipopneia (IAH) em 6,98, enquanto os pacientes do Padrão III tinham esse índice atenuado em 11,45. Para o tipo facial, os pacientes braquifaciais apresentaram um IAH médio de 22,34, enquanto o grupo classificado como dolicofacial mostrou um índice menor, de 10,52, com significância estatística. Conclusão: o desenho morfológico facial se mostrou um considerável fator de agravamento ou proteção da SAOS, onde os indivíduos Padrão II e braquifaciais tiveram IAH maiores, enquanto nos pacientes Padrão III esse índice foi reduzido.

ABSTRACT

Nos últimos anos, o percentual de pacientes que tiveram indicação de extrações como parte do tratamento ortodôntico diminuiu consideravelmente. Acreditamos que um dos motivos desta diminuição, seja a utilização do sistema autoligável na prática ortodôntica. Com este sistema a Ortodontia retornou à filosofia expansionista idealizada por Angle, e isto talvez, traga consigo as mesmas preocupações de Tweed na primeira metade do século passado. O emprego de forças leves, nunca antes praticadas no manejo terapêutico das más oclusões, tem se mostrado seguro para o periodonto e um diagnóstico morfológico facial acurado tem poupado as alterações inadvertidas no perfil. O objetivo deste trabalho é, através de casos clínicos, mostrar a eficiência dos sistemas autoligáveis para soluções de apinhamento moderados e severos, sem extrações em faces compatíveis com metas terapêuticas expansionistas.


In recent years, the percentage of patients who were referred to extractions as part of orthodontic treatment has decreased considerably. We believe that one of the reasons for this decrease is the use of self ligating system in orthodontic practice. With this system orthodontics has returned to expansionist philosophy devised by Angle, which may bring with it the same Tweed’s concerns from the first half of the last century. The use of light forces, never before practiced in the therapeutic management of malocclusions, hasproven to be safe for periodontal, and an accurate facial morphology diagnosis has avoided inadvertent changes in the profile. The objective of this study is to show, through clinical cases, the effectiveness of self-ligating systems, for moderate and severe crowding solution without extractions in faces compatible with expansionist therapeutic goals.

ABSTRACT

Objetivo: identificar as condições de higiene bucal, principalmente em relação ao uso do fio dental, em pacientes submetidos ao tratamento ortodôntico fixo. Material e métodos: um questionário sobre as atuais práticas de higiene bucal foi respondido por 200 indivíduos entre 11 e 25 anos de idade, sendo 100 do sexo feminino e 100 do sexo masculino, em fase ativa de tratamento ortodôntico fixo. Resultados: os resultados avaliados pela estatística, por meio de teste de comparação entre as faixas etárias, correlação, associação e distribuição de frequência, revelaram que a maioria dos pacientes (66%) escova os dentes duas vezes ao dia; utiliza escovas de dente convencionais (100%), ao invés de escova elétrica, e apenas 35,55% utiliza rotineiramente fio dental.


Objective: this study analyzed the oral hygiene status, especially concerning the use of dental floss, in patients submitted to fixed orthodontic treatment. Material and methods: a questionnaire on the current oral hygiene practices was responded by 200 individuals aged 11 to 25 years, being 100 females and 100 males, in active stage of fixed orthodontic treatment. Results: the results were statistically analyzed by comparison between age ranges, correlation, association and frequency distribution, and revealed that; there is positive correlation between age and frequency of toothbrushing; there is association between age and use of dental floss. Conclusions: analysis of the oral hygiene practice of orthodontic patients revealed that most patients (66%) brush their teeth twice a day; use conventional toothbrushes (100%) rather than electric toothbrushes and only 35.55% make routine use of dental floss.

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

A mordida aberta anterior apresenta-se com grande incidência em pacientes jovens, sendo de fácil solução quando interceptada precocemente. Essa má oclusão está relacionada a hábitos deletérios, como sucção de dedo e chupeta, sendo mantida posteriormente pela interposição lingual. Entretanto, a literatura é escassa em tratamento desta maloclusão em dentição permanente. Existem diferentes terapias ortodônticas que podem ser empregadas para correção da mordida aberta. O objetivo deste artigo é descrever uma forma de tratamento com o mínimo de efeitos colaterais e cooperação do paciente.


The anterior open bite presents a high incidence in young patients, it hás been easily resolved when intercepted early. This malocclusion is related to harmful habits such as thumb-sucking and pacifier, and maintained thereafter by the thong interposition. However, the literature is poor on treatment of this malocclusion in permanent dentition. There are different orthodontic therapies that can be used to open bite correction. The aim of this paper is to describe a form of treatment with minimal collateral effects and patient cooperation.
