Abstract(s)
Nos últimos anos, temos assistido a uma verdadeira revolução no campo da medicina dentária protética, graças ao desenvolvimento de novas tecnologias. Atualmente, o método convencional de realização de impressões para o planeamento em prótese fixa consiste na realização impressões com elastómeros. A precisão da impressão depende de vários fatores: o material, tipo e técnicas de impressão. Cada passo introduz potenciais erros humanos e/ou do material. A evolução dos sistemas informáticos para a produção de coroas, associadas ao desenvolvimento de novas microestruturas dos materiais cerâmicos, causou uma mudança importante no fluxo de trabalho clínico dos profissionais, bem como nas opções de tratamento oferecidas aos pacientes. Deste modo, com o avanço tecnológico é possível a obtenção de work flow digital e/ou misto, quer seja na obtenção de modelos, enceramento de diagnóstico, mock-up ou na confeção das coroas definitivas. Este trabalho tem como objetivo realizar uma revisão bibliográfica narrativa de modo a perceber/avaliar/comparar as vantagens/limitações do método convencional versus método digital no planeamento com prótese fixa até à fase da seleção do material cerâmico a utilizar na reabilitação.
In recent years, we have seen a real revolution in the field of prosthetic dentistry, thanks to the development of new technologies. Currently, the conventional method of making impressions for planning in fixed prosthesis consists of making impressions with elastomers. Impression accuracy depends on several factors: the material, type and impression techniques. Each step introduces potential human and/or material errors. The evolution of computer systems for the production of crowns, associated with the development of new microstructures of ceramic materials, has caused an important change in the clinical workflow of professionals, as well as in the treatment options offered to patients. Thus, with technological advances it is possible to obtain digital and/or mixed work flow, whether it be in obtaining models, diagnostic waxing, mock-up or in the making of the definitive crowns. This work aims to carry out a narrative bibliographic review in order to understand/evaluate/compare the advantages/limitations of the conventional versus digital method in planning with fixed prosthesis until the selection phase of the ceramic material to be used in the rehabilitation.
