Resumo: Objective: To compare the accuracy and reliability of intra- and inter-arch linear measurements obtained from 3D digital models from intraoral scanning and from scanning conventional models. Material and Methods: The sample consisted of 25 volunteers (11 and 14 women) with a mean age of 29.6 years, who had their dental models divided into three groups: Group T, digital models from scanning with a Trios® intraoral scanner; Group P, models from scanning with a Panda® intraoral scanner and Control group, models from scanning conventional models with an E3® desktopscanning, previously obtained through molding with alginate Hydrogum®. Seventy five pairs of three-dimensional digital models were analyzed. Orthoanalyzer software was used for the evaluation of measurements from this study including: Mesiodistal size of the teeth, clinical height of the crown, Intercanine, interpremolar and molar distances, perimeter and arch length, overjet and overbite. The normality of the variables was tested using the Shapiro-Wilk test. Intergroup comparisons were performed using repeated measures ANOVA and Tukey\'s tests (P<0.05). Results: The normality of the sample was confirmed. All variables showed good and excellent reliability with ICC ranging from 0.808 to 0.987 and 0.814 to 0.950 from the Intra- and inter-examiner reproducibility assessment, respectively. No significant differences were found between the three study groups. Conclusion: Both intraoral scanning devices showed similar accuracy.

Material e Métodos: A amostra foi constituída por 25 voluntários (11 homens e 14 mulheres) com idade média de 29,6 anos, que tiveram seus modelos dentários divididos em três grupos: Grupo T, Modelos digitais do escaneamento com scanner intraoral Trios®; Grupo P, modelos do escaneamento com scanner intraoral Panda® e Grupo controle: Modelos do escaneamento de modelos de gesso com scanner de bancada E3®, previamente obtidos por moldagem com alginato Hydrogum®. Setenta e cinco pares de modelos digitais tridimensionais foram analisados. O software Orthoanalyzer foi utilizado para a avaliação das medidas deste estudo, incluindo: Tamanho mesiodistal dos dentes, altura clínica da coroa, distâncias intercaninos, inter pré-molares e molares, perímetro e comprimento do arco, sobressaliência e sobremordida. A normalidade das variáveis foi testada por meio do teste de Shapiro-Wilk. As comparações intergrupos foram realizadas usando ANOVA para medidas repetidas e testes de Tukey (P <0,05). Resultados: A normalidade da amostra foi confirmada. Todas as variáveis apresentaram confiabilidade boa e excelente com ICC variando de 0,808 a 0,987 e 0,814 a 0,950 na avaliação da reprodutibilidade intra e Interexaminadores, respectivamente. Não foram encontradas diferenças significativas entre os três grupos de estudo. Conclusão: Ambos os aparelhos de escaneamento intraoral apresentaram acurácia semelhante.Biblioteca Digitais de Teses e Dissertações da USPHenriques, Jose Fernando CastanhaCavalcanti, Heloísa Nelson2023-03-21info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/25/25144/tde-18052023-173246/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPReter o conteúdo por motivos de patente, publicação e/ou direitos autoriais.info:eu-repo/semantics/openAccesseng2024-08-02T16:12:02Zoai:teses.usp.br:tde-18052023-173246Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212024-08-02T16:12:02Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false
