RESUMO

OBJECTIVE: The aim of this study is to assess the microbial contamination of three different brands of esthetic elastomeric ligatures. MATERIALS AND METHODS: Different brands of esthetic ligatures (Unistick Pearl [American Orthodontics, Sheboygan, WI, USA], Power Sticks Pearl [Ortho Technology, Tampa, FL, USA], and Ease [Obscure, 3M Unitek, Monrovia, CA, USA]) were randomly assigned to permanent canines of 25 patients (aged 11-18 years) undergoing corrective orthodontic treatment. After 30 days, the ligatures were removed, processed, and the biofilm composition was analyzed by checkerboard DNA-DNA hybridization for 40 bacterial species. The microbiological data were analyzed using a nonparametric mixed model. RESULTS: The ligatures presented intense microbial contamination after 30 days, but no statistically significant differences were observed among the three groups (p > 0.05). The levels of the evaluated individual species and proportions of the microbial complexes showed no statistically significant differences among the ligature groups (p > 0.05). CONCLUSIONS: Esthetic elastomeric ligatures became multicolonized by several bacterial species after 30 days of exposure to the oral cavity. However, no relevant differences were observed among the biofilm composition formed on the different ligature brands.

RESUMO

ABSTRACT Introduction: Extraction vs. non-extraction is a crucial decision in orthodontic therapy. Objective: The aim of the present study was to investigate the changes in the dental arch width and buccal corridor after orthodontic treatment using extraction and non-extraction therapy with Damon self-ligating system. Material and Methods: This retrospective study consisted of 35 patients (20 female and 15 male patients with median age of 12.5 years), treated by extracting 4 or 2 premolars, and 37 patients (16 female and 21 male patients with the median age of 12.8 years), treated without premolar extraction. Both groups were treated with Damon self-ligating system. Plaster models before (T0) and after (T1) treatment were measured, and the arch width values were determined at the level of the first molars, second premolars, canines and palatal rugae. Buccal corridor width was measured using the extraoral images at T0 and T1. Paired t-test was used for the analysis of the normally distributed data, and Wilcoxon Mann-Whitney U test was used for the data with non-normal distribution. Values of p<0.05 were set as statistically significant. Results: The upper intercanine width increased significantly in both groups (p<0.01). In the non-extraction group, the arch width increased significantly in the maxillary second premolar and first molar region (p<0.01) as well as in the region of the canines (p=0.04), second premolars (p=0.01) and first molars (p<0.01) of the mandible. The buccal corridor decreased significantly in the non-extraction group (p<0.01). Conclusion: Premolar extraction in combination with Damon self-ligating system did not lead to reduction of the dental arch width in the maxilla, nor did it increase the size of the buccal corridors.

RESUMO Introdução: Extrair ou não extrair dentes é uma decisão crucial no tratamento ortodôntico. Objetivo: O objetivo do presente estudo foi investigar as alterações na largura da arcada dentária e no corredor bucal após o tratamento ortodôntico com extração e o tratamento sem extração com o sistema autoligável Damon. Material e Métodos: Esse estudo retrospectivo consistiu de 35 pacientes (20 do sexo feminino e 15 do sexo masculino, com idade média de 12,5 anos), tratados com extração de 4 ou 2 pré-molares; e 37 pacientes (16 do sexo feminino e 21 do sexo masculino, com idade média de 12,8 anos), tratados sem extração de pré-molares. Ambos os grupos foram tratados com o sistema autoligável Damon. Os modelos de gesso antes (T0) e depois (T1) do tratamento foram medidos, e os valores de largura da arcada foram determinados ao nível dos primeiros molares, segundos pré-molares, caninos e rugas palatinas. A largura do corredor bucal foi medida usando as imagens extrabucais em T0 e T1. O teste t pareado foi usado para a análise dos dados com distribuição normal, e o teste U de Wilcoxon Mann-Whitney foi usado para os dados com distribuição não normal. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados: A distância intercaninos superiores aumentou significativamente em ambos os grupos (p<0,01). No grupo sem extração, a largura da arcada aumentou significativamente na região dos segundos pré-molares e primeiros molares superiores (p<0,01), bem como na região dos caninos (p=0,04), segundos pré-molares (p=0,01) e primeiros molares (p<0,01) inferiores. O corredor bucal diminuiu significativamente no grupo sem extração (p<0,01). Conclusão: A extração de pré-molares em combinação com o sistema autoligável Damon não levou à redução na largura da arcada dentária superior, nem aumentou o tamanho dos corredores bucais.

RESUMO

Aim: The aim of this review was to systematically assess and report the effectiveness of chlorhexidine (CHX) mouthwash in preventing plaque accumulation and gingivitis in patients undergoing orthodontic treatment. Material and Methods: The review was prepared according to the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines and registered under PROSPERO database (CRD42020170776). Four electronic databases were systematically searched along with a complimentary manual search of orthodontic journals until June 2022. Only Randomized Control Trials (RCTs) reporting on antiplaque and antigingivitis efficacy of Chlorhexidine mouthwash compared with placebo or control in orthodontic patients were included. Risk of bias assessment was done using Cochrane ROB-2. Quantitative analysis (Random-Effects Model and Standard Mean Difference (SMD)) with 95 % confidence interval was used. Results: Six RCTs were included for qualitative analysis and four were included for quantitative analysis with a total of 211 participants. Out of six studies, 3 were judged to have a low risk of bias, two had some concerns and one of them had high risk of bias. Random effects meta-analysis performed for anti-plaque effect reported a significant reduction of -1.2 SMD for CHX at 4 to 6 weeks with low heterogeneity (I2-35%). The anti-gingivitis effect at 4 to 6 weeks was significant for CHX with a SMD of -1.03 and a moderate heterogeneity (I2-65%). Conclusion: On analyzing the available evidence a moderate level of certainty supports a short-term reduction in plaque accumulation and gingivitis in orthodontic patients subjected to rinsing with chlorhexidine oral rinse.

RESUMO

RESUMEN Introducción: En sus inicios la mayoría de los aparatos funcionales fueron removibles, pero cada día más se incrementan los fijos. Su combinación puede incrementar la eficacia en el tratamiento del retrognatimo mandibular. Objetivo: Presentar los resultados del tratamiento con el botón de Nance modificado en una paciente con retrognatismo mandibular. Caso clínico: Paciente femenina de 13 años de edad, que presenta perfil convexo, disfunción neuromuscular, dentición permanente en ambos maxilares con presencia de ligero apiñamiento anterior, relación molar bilateral de distoclusión de ½ unidad, resalte y sobrepase incisivos de 6 mm, mala relación intermaxilar causada por retrognatismo de la mandíbula y escaso remanente de crecimiento mandibular activo. La primera etapa del tratamiento, incluyó psicoterapia, mioterapia y avance mandibular con un aparato funcional fijo (botón de Nance modificado para la propulsión mandibular). A los nueve meses de iniciar el tratamiento se comprobó el cambio en las relaciones intermaxilares en sentido antero-posterior, con disminución del ángulo ANB hasta 20 e incremento del SNB a 78, como reflejo de una buena relación de las bases ósea por crecimiento mandibular. Conclusiones: El tratamiento realizado a la paciente con el botón de Nance modificado para la propulsión mandibular, permitió la obtención de relaciones intermaxilares favorables.

ABSTRACT Introduction: In the beginning, most of the functional appliances were removable, but the fixed ones are increasing every day. Their combination can increase the effectiveness in the treatment of mandibular retrognathymus. Objective: To present the results of the treatment of a patient with mandibular retrognathism treated with the modified Nance button. Case report: A 13-year-old female patient with convex profile, neuromuscular dysfunction, permanent dentition in both jaws with the presence of slight anterior crowding, bilateral distoclusion molar ratio of ½ unit, incisor protrusion and overhang of 6 mm, poor intermaxillary relationship caused by retrognathism of the mandible and little remnant of active mandibular growth. The first stage of treatment included psychotherapy, myotherapy and mandibular advancement with a fixed functional appliance (modified Nance button for mandibular propulsion). Nine months after starting the treatment, the change in the intermaxillary relationships in the anteroposterior direction was verified, with a decrease in the ANB angle to 20 and an increase in the SNB to 78, as a reflection of a good relationship of the bone bases due to mandibular growth. Conclusions: One year after treatment with the modified Nance button for mandibular propulsion, a correct relationship of the patient's bone bases was achieved.

RESUMO

Com intuito de pontuar os paralelos entre as técnicas ortodônticas com aparelhagem fixa e alinhadores transparentes, este estudo propôs revisar a literatura científica sobre alinhadores ortodônticos removíveis versus aparelhos ortodônticos fixos. Foram selecionados artigos de 2005 a 2021, utilizando as bases de dados PubMed, Scopus, Web of Science, Cochrane Library, Clinical Trials e Opengrey. Os artigos abordavam temáticas como sensação dolorosa, saúde periodontal, higiene, microbiota, reabsorção radicular, qualidade de vida e efetividade do tratamento. Os alinhadores apresentaram maior aceitabilidade pelos pacientes e vantagens claras em relação à dor, higiene, qualidade de vida, reabsorção radicular e saúde periodontal, sendo inferior aos aparelhos ortodônticos fixos na efetividade do tratamento e na interferência na fala.

In order to point out the parallels between orthodontic techniques with fixed appliances and transparent aligners, this study proposed to review the scientific literature on removable orthodontic aligners versus fixed orthodontic appliances. Articles from 2005 to 2021 were selected, using the PubMed, Scopus, Web of Science, Cochrane Library, Clinical Trials and OpenGrey databases. The articles addressed issues such as pain, periodontal health, hygiene, microbiota, root resorption, quality of life and treatment effectiveness. Aligners showed greater acceptability by patients and clear advantages in relation to pain, hygiene, quality of life, root resorption and periodontal health, being inferior to fixed orthodontic appliances in terms of effectiveness and speech capacity.

RESUMO

Introduction: Dental malocclusion is a public health problem and orthodontics is the specialty in charge of diagnosing and treating it, aesthetic brackets are an alternative, the costs are varied, which makes its precision doubtful. Objective: Evaluate the measurement and geometry of the slot of three brands of aesthetic brackets and verify their precision. Material and Methods: Twenty-four aesthetic Roth prescription 0.022" slot polycrystalline ceramic brackets were evaluated in three brands: American Orthodontics (United States), Morelli (Brazil) and Class One (China). Eight samples were measured per group in a specialized laboratory certified in measurement and calibration, the measurements of internal and external height were verified, per mesial and distal; and the parallelism of the slot of each bracket. The results were processed with SPSS 22 and tests of variance (ANOVA), Tukey and Student's t were used. Results:The measurements of the brackets' grooves do not correspond to the measurements announced by the manufacturers, these are greater, however, American Orthodontics is within the tolerance range (p<0.01); the slots in the mesio-distal direction and the lingual vestibule are not parallel in Morelli and Class One. Conclusion: The results of this study indicate that the slots of the supports are oversized, their geometry is not precise and varies greatly between brands and prices. The three-dimensional control of the tooth could be compromised.

RESUMO

La evolución de la ortodoncia, desde sus inicios, ha demostrado hechos destacables como el surgimiento de la técnica de arco recto, el desarrollo de prescripciones variadas, el uso de ranuras con diferentes dimensiones, sistemas de anclaje esquelético, tomografía... A pesar de ello, los diseños y las características que presentaban los brackets eran siempre los mismos y limitados. La historia de las grandes ideas es vasta, pero debían estar unidas en una sola pieza. Esto es lo que hicieron los autores de este artículo, al desarrollar un nuevo diseño de bracket que cuenta con dos slots centrales y cada una con diferentes dimensiones, un slot tiene dimensiones de 0.018 "X 0.030" y el otro 0.022 "X 0.028", abriéndse una gama de posibilidades. A partir de ahora contamos con una herramienta de trabajo con varios recursos, que genera grandes beneficios para profesionales y pacientes, y que gana cada día más seguidores (AU)

RESUMO

Com o intuito de obter resultados clínicos cada vez mais precisos nos tratamentos ortodônticos, as novas tecnologias de colagem in- direta têm assumido um papel relevante na Ortodontia. Com o desenvolvimento dos meios de obtenção e manipulação das imagens digitais, surgiu a possibilidade de realizar o planejamento ortodôntico no ambiente virtual, simulando o resultado desejado, bem como o melhor posicionamento dos acessórios ortodônticos nos dentes para atingir esse objetivo. A possibilidade de impressão tridimensional a partir da tecnologia CAD/CAM permitiu que a guia para a transferência dos bráquetes, na colagem indireta, fosse confeccionada diretamente no software após planejamento digital da posição dos mesmos. Atualmente, algumas empresas têm disponibilizado pro- gramas ou ofertado a possibilidade de executar planejamento digital, bráquetes customizados, arcos personalizados e guias para a colagem indireta. Este artigo tem o objetivo de realizar uma revisão de literatura reunindo informações recentes sobre colagem indireta utilizando o sistema CAD/CAM em relação à precisão de colagem e tempo do tratamento ortodôntico. Conclui-se que a colagem indireta por meio de sistemas CAD-CAM apresenta confiabilidade em relação à precisão do posicionamento dos bráquetes.Em relação ao tempo de tratamento, diversos estudos sugerem que este foi reduzido com o método, porém, a variedade de técnicas e softwares existentes, além da diversidade dos métodos científicos, indicam a necessidade de mais investigações. Apesar disso, a colagem indireta digital tem se mostrado uma opção interessante a ser incorporada ao tratamento ortodôntico.

New indirect bonding technologies have assumed an important role in Orthodontics to obtain increasingly accurate clinical results in orthodontic treatments. With the development of means of obtaining and manipulating digital images, the possibility to carry out orthodontic planning in the virtual environment arose, simulating the desired result, as well as the best positioning of orthodontic accessories on teeth to achieve this goal. The possibility of three-dimensional printing using CAD/CAM technology allowed the guide for the transfer of brackets, in indirect bonding, to be made directly in the software after digital planning of their position. Currently, some companies have made programs available or offered the possibility of executing digital planning, customized brackets, personalized arches and guides for indirect bonding. This article aims to perform a literature review, gathering recent information on indirect bonding using the CAD/CAM system in relation to bonding accuracy and time of orthodontic treatment. It is concluded that the indirect bonding using CAD/CAM systems presents reliability in relation to the precision of the positioning of brackets. Regarding the treatment time, several studies suggest that it was reduced with the method, however, the variety of existing techniques and software, in addition to the diversity of scientific methods, indicate the need for further investigations. Despite this, indirect digital bonding has proved to be an interesting option to be incorporated into orthodontic treatment.
