Resumo: | Traditionally, fixed prostheses based on base metal alloys were retained on their abutments with powder-liquid cement (zinc phosphate, polycarboxylate, glass ionomer). Currently, with the development of CAD-CAM, there is a tendency to make conservative dental preparations. Undoubtedly it is a very good technique, concerning healthy dental tissue. But the resulting restorations would already need cement and adhesives that capable of chemically bonding to the different substrates, so as not to peel off. Manufacturers indicate that molecules such as 10 MDP, VBDATDT, 4-META can bind to metals. METHOD. 30 CoCr cylinders were divided into 3 groups. With the first, sandblasting was carried out and an adhesive agent based on 10 MDP was immediately placed to cement 4 resin microtubes using a resinous cement. The remaining groups were sandblasted in the same way, but in them, it was decided to wait for 24 and 48 hours to perform the adhesive procedure. RESULTS. The immediate group reached the highest values of bond strength. When more time was waited after sandblasting, the lowest values were obtained, even after aging. CONCLUSIONS. CoCr alloys can be cemented with resinous cement, as long as a correct mechanical and chemical surface treatment is carried out. |

Actualmente con el desarrollo del CAD CAM, existe la tendencia a realizar preparaciones dentales conservadoras. Indudablemente es una muy buena técnica, por el respeto del tejido dental sano. Pero las restauraciones resultantes ya necesitarían de cementos y adhesivos que sean capaces de adherirse químicamente a los diferentes sustratos, para no despegarse. Fabricantes indican que, moléculas como el 10 MDP, el VBDATDT, 4-META pueden unirse a los metales. MÉTODO. 30 cilindros de CoCr fueron divididos en 3 grupos. Con el primero, se procedió a arenar e inmediatamente se colocó un agente adhesivo a base de 10 MDP para cementar 4 microtubos de resina por medio de un cemento resinoso. Con los grupos restantes de igual manera se arenó, pero en ellos se decidió esperar 24 y 48 horas para realizar el procedimiento adhesivo. RESULTADOS. El grupo inmediato alcanzó los mas altos valores de resistencia de unión. Cuando se esperó mas tiempo después de arenar se obtuvieron los más bajos valores, incluso después de envejecidos. CONCLUSIONES. Las aleaciones de CoCr pueden ser cementadas con cementos resinosos, siempre y cuando se realice un correcto tratamiento mecánico y químico de su superficie.SciELO PreprintsSciELO PreprintsSciELO Preprints2021-06-07info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/240210.1590/SciELOPreprints.2402spahttps://preprints.scielo.org/index.php/scielo/article/view/2402/4081Copyright (c) 2021 Marcelo Cascante Calderón, Lesly Chacón Flores, Karen Guevara Guamán, Michelle Celi Gonzaga, Gisella Quiroz Cevallos, Paola Cangas Bedoya, Valeria Quinapallo Lópezhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCalderón, Marcelo CascanteFlores, Lesly ChacónGuamán, Karen GuevaraGonzaga, Michelle CeliCevallos, Gisella QuirozBedoya, Paola CangasLópez, Valeria Quinapalloreponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-05-27T21:28:39Zoai:ops.preprints.scielo.org:preprint/2402Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-05-27T21:28:39SciELO Preprints - SciELOfalse |
