Resumo: | The objective of this study was to clinically evaluate the marginal and internal fit of veneered ceramic crowns and compare to the adaptation obtained on the plaster die of the working cast. Twenty-five molar layered crowns were made of zirconia (IPS e.max ZirCAD) and lithium disilicate glass-ceramic (IPS e.max Press). The marginal and internal fit, both clinically (on the preparation in the mouth) and on the plaster cast of the working cast, were evaluated using the silicone replica technique. The replicas were cut into two segments, resulting in four fragments, and digitized in high resolution. Four points were evaluated: margin (MG), axial wall (AW), axio-occlusal angle (AO) and occlusal area (CO). Data were analyzed by paired and unpaired Student's t-test (α = 5%). Considering each of the evaluated points, clinically (on the preparation in the mouth), there was no significant difference when comparing the zirconia and glassceramic crowns [MG (p = 0.212), AW (p = 0.918), AO (p = 0.765), CO (p = 0.897)]. Comparing the marginal and internal fit on die and clinically, for glass-ceramic crowns, there was no significant difference [MG (p = 0.975), AW (p = 0.406), AO (p = 0.493), CO (p = 0.844)]. For zirconia, there was no significant difference in 3 of the 4 points [MG (p = 0.727), AW (p = 0.209), CO (p = 0.212)], except for the AO point (p = 0.017, in mouth 151.5 ±57.1 μm and on the die 191.8±47.9 μm). It can be concluded that, clinically, the marginal and internal fit of lithium disilicate glass-ceramic and zirconia crowns was similar in all assessed points. On the other hand, when comparing the marginal and internal fit of the crowns on plaster die of the working model and clinically, in the mouth, the zirconia crowns presented greater clinical misfit at the axioocclusal angle. |

Vinte e cinco coroas estratificadas em molares foram confeccionadas em zircônia (IPS e.max ZirCAD) e vitrocerâmica a base de dissilicato de lítio (IPS e.max Press). A adaptação marginal e interna, tanto clinicamente (sobre o preparo em boca), como sobre o troquel de gesso do modelo de trabalho, foi avaliada pela técnica da réplica em silicone. As réplicas foram cortadas em dois segmentos, resultando em quatro fragmentos e digitalizadas em alta resolução. Foram avaliados quatro pontos: margem (MG), parede axial (AW), ângulo áxio-oclusal (AO) e área oclusal (CO). Os dados foram analisados por teste-t de Student pareado e não pareado (α = 5%). Considerando-se cada um dos pontos avaliados, clinicamente (sobre o preparo em boca), não houve diferença significante quando comparadas as coroas de zircônia e vitrocerâmica [MG (p = 0,212), AW (p = 0,918), AO (p = 0,765), CO (p = 0,897)]. Comparando-se a adaptação marginal e interna sobre troquel e clinicamente, para coroas em vitrocerâmica, não houve diferença significante [MG (p = 0,975), AW (p = 0,406), AO (p = 0,493), CO (p = 0,844)]. Para zircônia, não houve diferença significativa em 3 dos 4 pontos [MG (p = 0,727), AW (p = 0,209), CO (p = 0,212)], com exceção do ponto AO (p = 0,017, em boca 151,5±57,1μm e sobre o troquel 191,8±47,9 μm). Pode-se concluir que clinicamente, a adaptação marginal e interna de coroas cerâmicas de vitrocerâmica de dissilicato de lítio e zircônia foi semelhante em todos os pontos analisados. Já na comparação da adaptação marginal e interna das coroas sobre troquel de gesso do modelo de trabalho e clinicamente, em boca, as coroas de zircônia apresentaram maior desadaptação no ângulo áxio-oclusal.Universidade PositivoBrasilOdontologiaPPG1UPGonzaga, Carla Castigliahttp://lattes.cnpq.br/0246614895218572Serpa, Gabriela Andrade2022-10-06T18:07:10Z20212022-10-06T18:07:10Z2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://repositorio.cruzeirodosul.edu.br/handle/123456789/4075porinfo:eu-repo/semantics/openAccessreponame:Repositório do Centro Universitário Braz Cubasinstname:Centro Universitário Braz Cubas (CUB)instacron:CUB2022-10-06T18:07:59Zoai:repositorio.cruzeirodosul.edu.br:123456789/4075Repositório InstitucionalPUBhttps://repositorio.brazcubas.edu.br/oai/requestbibli@brazcubas.edu.bropendoar:2022-10-06T18:07:59Repositório do Centro Universitário Braz Cubas - Centro Universitário Braz Cubas (CUB)false |
