This study aimed to analyze two cases of fracture of the metal framework of Co-Cr-based removable partial dentures, using fractography to identify a true cause of these failures. The first case concerned the coupling between the smaller and larger connectors; the patient brought his fractured removable partial dentures to the clinic. The second case referred to a larger connector; structure of the patient fractured during the test. For failure analysis, images of two fractured metal frameworks were taken by scanning electron microscopy to identify the origin of the fracture and to determine the mechanisms involved in the process. Subsequently, energy dispersive X-ray spectroscopy was used for elemental chemical mapping of the fracture interface. The fractography indicated material fatigue as a possible cause in the first case and an error in the casting process in the second. The energy dispersive X-ray spectroscopy test, performed in the specimen of case B, showed predominant and characteristic peaks for Co and Cr, with a higher concentration of chromium. The fractures identified were associated with inclusions and with material fatigue and a number important characteristics were evidenced by the technique.
O presente trabalho tem como objetivo debater como o marketing (que ganhou muita importância no meio digital, nos últimos anos) pode melhorar a imagem da empresa, quando bem feito e respeitando a ética odontológica, e explanar sobre gestão de clínicas odontológicas – visto que organização de documentos, respeito aos cronogramas e controle de custos acarreta em maior excelência, além de diminuir gastos e amortecer riscos –, encontrando assim soluções com a finalidade de dinamizar o desempenho dos estabelecimentos. Trata-se de uma revisão da literatura, na qual foi realizada uma busca eletrônica de publicações na base de dados PubMed, Lilacs e Scielo, utilizando-se as seguintes palavras-chave, obtidas de acordo com o Medical Subject Headings (MeSH): odontologia, marketing e gestão, com o operador booleano “AND”; sendo selecionados 7 trabalhos. Conclui-se que é essencial que os cursos de graduação em odontologia adotem modelos mais efetivos sobre o assunto não técnico para a formação de novos profissionais, o que melhorará a qualidade de serviços prestados e possibilitará maiores chances de sucesso profissional e financeiro da empresa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
