Resumo(s)
Os alinhadores ortodônticos oferecem diversas vantagens em relação aos aparelhos fixos tradicionais, como aceitabilidade, eficiência, facilidade de higiene e versatilidade. Torna-se relevante salientar que eles também apresentam algumas limitações e desafios, como a necessidade de cooperação do paciente, dificuldade de controlo da rotação e inclinação dos dentes posteriores, entre outros movimentos, além do custo elevado e falta de evidências científicas quanto à durabilidade dos resultados a longo prazo. Desta forma, o presente estudo pretende avaliar a eficácia imediata e a estabilidade dos resultados alcançados com o uso de alinhadores ortodônticos no tratamento de maloclusões dentárias no formato scoping review. Para tal, a pesquisa foi conduzida utilizando o motor de busca de acesso livre PubMed, as bases de dados Cochrane, periódicos da CAPES, e Medline, com foco em estudos publicados de 2019 a 2023. A metodologia seguiu as diretrizes PRISMA e o modelo PICO. Foram analisados 89 artigos, tendo sido selecionados 18 para uma avaliação abrangente. Entre os resultados obtidos encontrou-se que os alinhadores transparentes demonstraram eficácia na correção de maloclusões simples a moderadas, com menos dor e impacto na qualidade de vida, alcançando bons resultados de médio e longo prazo. Entretanto as revisões selecionadas neste scoping review também revelaram alguma limitação dos alinhadores transparentes em alcançar os mesmos resultados que os aparelhos fixos nos tratamentos mais complexos, sendo necessária a utilização de recursos adicionais (como botões, elásticos, mini-implantes, etc) para tal. Desta forma percebe-se que, identificando suas limitações e dominando a técnica, os alinhadores ortodônticos mostram-se eficazes nos tratamentos de pequena e média complexidade, e que, quando utilizados de forma híbrida com outros dispositivos ortodônticos, possuem potencial em alcançar bons resultados mesmo em casos mais complexos, embora sejam necessários mais estudos que corroborem isso.

It is important to note that they also present some limitations and challenges, such as the need for patient cooperation, difficulty in controlling the rotation and inclination of the posterior teeth, among other movements, as well as the high cost and lack of scientific evidence as to the long-term durability of the results. Therefore, this study aims to evaluate the immediate effectiveness and stability of the results achieved with the use of orthodontic aligners in the treatment of dental malocclusions in a scoping review format. To this end, the research was conducted using the open-access search engine PubMed, the Cochrane databases, CAPES journals, and Medline, focusing on studies published from 2019 to 2023. The methodology followed the PRISMA guidelines and the PICO model. A total of 89 articles were analyzed and 18 were selected for a comprehensive evaluation. Among the results obtained, it was found that transparent aligners showed efficacy in correcting simple to moderate malocclusions, with less pain and impact on quality of life, achieving medium- and long-term good results. However, the reviews selected in this scoping review also revealed some limitations of transparent aligners in achieving the same results as fixed appliances in more complex treatments, requiring the use of additional resources (such as buttons, elastics, mini-implants, etc.) to do so. In this way, it can be seen that, by identifying their limitations and mastering the technique, orthodontic aligners are effective in small and medium complexity treatments and that, when used in a hybrid way with other orthodontic devices, they have the potential to achieve good results even in more complex cases, although more studies are needed to corroborate this.
