Introdução: A crescente digitalização na medicina dentária tem impulsionado o uso de scanners intraorais como alternativa aos métodos convencionais de moldagem para o planeamento de tratamentos ortodônticos. Essa tecnologia permite a aquisição de modelos digitais tridimensionais da arcada dentária, proporcionando maior conforto ao paciente, redução do tempo clínico e integração com softwares de planeamento virtual. No entanto, a precisão desses dispositivos é essencial para garantir diagnósticos confiáveis e a execução correta dos planos de tratamento.
Objetivo: Esta revisão sistemática, tem como objetivo avaliar a precisão dos scanners intraorais utilizados na ortodontia, comparando-os com métodos tradicionais e entre diferentes modelos de scanners disponíveis no mercado, com base em estudos publicados entre 2014 e 2024.
Materiais e métodos: A pesquisa bibliográfica foi realizada nas bases de dados PubMed, ScienceDirect e Scopus, tendo sido incluídos doze estudos que cumpriram os critérios de elegibilidade. Resultados: Os resultados revelaram que os scanners intraorais oferecem alta precisão e reprodutibilidade na captura da anatomia dentária, especialmente em digitalizações parciais e em arcos únicos. O scan intraoral pode ser o método ideal de obtenção de impressões e o futuro das impressões em ortodontia.
Conclusão: Futuramente, dever-se-ão elaborar estudos que permitam avaliar um grupo de crianças e adolescentes em comparação com um par de adultos para observar se há diferenças de confiabilidade entre grupos populacionais. São necessários também mais estudos que avaliem juntamente os vários dispositivos de scanner intraoral em conjunto com as impressões convencionais de forma a validar a sua precisão.
Introduction: The increasing digitalization of dentistry has driven the use of intraoral scanners as an alternative to conventional impression methods for orthodontic treatment planning. This technology allows the acquisition of three-dimensional digital models of the dental arch, providing greater patient comfort, reduced clinical time and integration with virtual planning software. However, the accuracy of these devices is essential to ensure reliable diagnoses and the correct execution of treatment plans. Objective: This systematic review aims to evaluate the accuracy of intraoral scanners used in orthodontics, comparing them with traditional methods and between different scanner models available on the market, based on studies published between 2014 and 2024. . Materials and methods: The literature search was carried out in the PubMed, ScienceDirect and Scopus databases, and twelve studies that met the eligibility criteria were included. Results: The results revealed that intraoral scanners offer high accuracy and reproducibility in capturing dental anatomy, especially in partial and single-arch scans. Intraoral scanning may be the ideal method for obtaining impressions and the future of impressions in orthodontics. Conclusion: In the future, studies should be conducted to evaluate a group of children and adolescents in comparison with a matched group of adults to observe whether there are differences in reliability between population groups. Further studies are also needed to evaluate the various intraoral scanner devices together with conventional impressions in order to validate their accuracy.
