A etapa clínica da seleção de cor dos dentes do paciente, para posterior confecção da prótese pelo técnico em prótese dentária determina o resultado estético das coroas protéticas em cerâmica. Objetivo:Este trabalho teve como objetivo avaliar a fidelidade da cor de diferentes cerâmicas feldspáti-cas: Porcelain EX-3 (Noritake, Japão), StarLight (Dentsply, Brasil) e HeramCeram (Heraeus, Alemanha) com as respectivas escalas de cor: Shade Guide (Noritake, Japão), Vita Clássica(Vita, Alemanha) e Pala (Heraeus, Alemanha). Metodologia: foram confeccionadas facetas cerâmicas reproduzindo os aspectos estéticos (forma, ma-tiz, croma e valor). Os corpos de prova foram padronizados no momento da estratificação e aplicação laboratorial da cerâmica. Resultados: As facetas confeccionadas após a determinação da cor foram comparadas à escala origi-nal do fabricante de cada cerâmica e apresentaram grandes diferenças nos aspectos estéticos avalia-dos que ratifica a importância do conhecimento das cerâmicas e o tipo de escala utilizada. Conclusão: A falta do conhecimento no momento da seleção da cor influencia no registro e mapea-mento da cor dos dentes pelo o cirurgião dentista. Isto poderá levar a insucessos na transmissão da informação com o laboratório de Prótese DentáriaIntroduction: Dental ceramics are considered the best materials for the preparation of veneers and pros-thetic crowns in anterior and posterior teeth. In addition to reproducing the color of the teeth with greater fidelity, they present aesthetic and biomechanical characteristics similar to dental tissues. The clinical stage of selecting the color of the patient’s teeth - for the subsequent fabrication of the prosthesis by the dental technician - determines the aesthetic result of ceramic prosthetic crowns.Objective: To evaluate the fidelity of the color of different feldspathic ceramics: Porcelain EX-3 (Noritake, Japan), StarLight (Dentsply, Brazil) and HeramCeram (Heraeus, Germany) with their respective color scales: Shade Guide (Noritake, Japan), Vita Classical (Vita, Germany) and Pala (Heraeus, Germany).Methodology: We made ceramic veneers that reproduced the aesthetic aspects (shape, shade, chroma and value). The veneers were standardized at the time of stratification and application of ceramics in the laboratory.Results: The veneers elaborated after determining the color were compared with the original scale of the manufacturer of each ceramic dental brand. They presented great differences in the esthetic aspects eva-luated. This confirms the importance of having knowledge of the ceramics and the type of scale that will be used.Conclusion:The lack of knowledge when selecting the color of the dental ceramic affects the registration and mapping of the color of the teeth that the oral surgeon will rehabilitate. This can cause failures in the transmission of information to the prosthesis laboratoryporUniversidade Federal de Minas GeraisUFMGBrasilFAO - DEPARTAMENTO DE ODONTOLOGIA RESTAURADORAFAO - DEPARTAMENTO DE ODONTOPEDIATRIA E ORTODONTIARevista Nacional de OdontologíaPrótese dentáriaCerâmicaCorDenteceramicFidelity colorComparação da fidelidade da cor de cerâmicas quando comparadas com as suas respectivas escalasComparación de la fidelidad del color de las cerámicas en relación con sus escalas respectivasComparison of the color fidelity of dental ceramics in relation to their respective scalesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://revistas.ucc.edu.co/index.php/od/article/view/2341Frederico dos Reis GoyatáJoão Batista Novaes JúniorIvan Doche BarreirosCélia Regina Moreira LanzaAmalia MorenoMaría Esperanza Cortés SeguraElissa TalmaAmanda Nascimento de Aguiarapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/49152/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALComparação da fidelidade da cor de cerâmicas quando comparadas com as suas respectivas escalas.pdfComparação da fidelidade da cor de cerâmicas quando comparadas com as suas respectivas escalas.pdfapplication/pdf5053099https://repositorio.ufmg.br/bitstream/1843/49152/2/Compara%c3%a7%c3%a3o%20da%20fidelidade%20da%20cor%20de%20cer%c3%a2micas%20quando%20comparadas%20com%20as%20suas%20respectivas%20escalas.pdf8ede701b580ae3d1b8c6783bb517d655MD521843/491522023-01-25 19:04:48.138oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-01-25T22:04:48Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
