Resumo: | Introduction: The aging of the population increases the need for prosthetic rehabilitation and the cost of dental care. To rehabilitate with quality and low cost is necessary to know the dental materials of this process, such as impression materials. The most used in Brazil is condensation silicon, which has limitations. However, the manufacturer modified the formula to improve dimensional stability. Objective: To evaluate the dimensional stability of Speedex condensation silicon with the new DCP technology at different casting times in fixed prosthesis moldings. Material and methods: A standard metal model with two cylinders of the same diameters and the same height was made to simulate a fixed prosthesis. A standard metal tray with drawers and insertion guides was developed. This metal tray was duplicated using reversible alginate. From this, four colorless acrylic trays were reproduced. In total, 20 impressions were made, with 5 impressions per group. The groups were cast with type IV gypsum at different times: group 1 (n = 5): immediate; Group 2 (n = 5): 30 min; group 3 (n = 5): 36h; group 4 (n = 5): 72h. The standard model and all gypsum models of groups 1, 2, 3 and 4 were measured by two researchers blindly using a digital caliper. The external and internal distances between the reference points of the cylinders were analyzed. The groups were compared by Student's t test, the significance level considered was p <0.05. Results: no statistically significant difference was found between researcher 1 and 2 by (p <0.05). There were no differences between groups 1 and 2 and 1 and 3; however, there was a significant difference between 1 and 4. Conclusion: Speedex condensing silicone does not change dimensional stability with leakage within 36 hours. |

Para reabilitar com qualidade e baixo custo é necessário conhecer os materiais odontológicos desse processo, como os materiais de moldagem. O mais utilizado no Brasil é a silicona de condensação, que possui limitações. Porém, o fabricante modificou a fórmula com o intuito de melhorar a estabilidade dimensional. Objetivo: avaliar a estabilidade dimensional da silicona de condensação Speedex com a nova tecnologia DCP, em diferentes tempos de vazamento nas moldagens para prótese fixa. Material e métodos: Foi confeccionado um modelo padrão metálico com dois cilindros de mesmos diâmetros e mesma altura para simular uma prótese fixa. Foi elaborada uma moldeira metálica padronizada com retenções e guias de inserção. A partir dessa, outras quatro, em acrílico incolor, foram reproduzidas pelo alginato reversível. No total, foram realizadas 20 impressões, sendo 5 impressões por grupo. Os grupos foram vazados com o gesso tipo IV em diferentes tempos: grupo 1 (n=5): imediato; grupo 2 (n=5): 30 min; grupo 3 (n=5): 36h; grupo 4 (n=5): 72h. O modelo padrão e todos os modelos de gesso do grupo 1, 2, 3 e 4 foram medidos por dois pesquisadores de forma cega com auxílio de um paquímetro digital. Foram analisadas as distâncias externas e internas entre os pontos de referência dos cilindros. Os grupos foram comparados pelo teste t de Student, o nível de significância considerado foi p<0,05. Resultados: não se observou diferença estatística entre as medidas do pesquisador 1 e 2 (p>0,05). Não houveram diferenças entre os grupos 1 e 2 e 1 e 3; porém houve diferença significativa entre o 1 e 4. Conclusão: A silicona de condensação Speedex, não altera a estabilidade dimensional com o vazamento em até 36 horas.Editora UFJF2019-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtOrapplication/pdfhttps://periodicos.ufjf.br/index.php/hurevista/article/view/2683410.34019/1982-8047.2019.v45.26834HU Revista; v. 45 n. 2 (2019); 156-1641982-80470103-3123reponame:HU Revista (Online)instname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFporhttps://periodicos.ufjf.br/index.php/hurevista/article/view/26834/19279Vidal Capelupi, RebecaSalvato de Souza, Viviam Tarcísio Martins, MarceloGouvêa Chagas, Júlio Marcos Teodoro de Aquino, Rogério dos Reis Furlani Zouain-Ferreira, ThalytaAparecida Mayrink de Oliveira, Fabiana info:eu-repo/semantics/openAccess2019-11-28T12:40:34Zoai:periodicos.ufjf.br:article/26834Revistahttps://periodicos.ufjf.br/index.php/hurevistaPUBhttps://periodicos.ufjf.br/index.php/hurevista/oairevista.hurevista@ufjf.edu.br1982-80470103-3123opendoar:2019-11-28T12:40:34HU Revista (Online) - Universidade Federal de Juiz de Fora (UFJF)false |
