Resumo: Purpose: The aim of this study was to evaluate the vertical marginal misfit of the metal framework of an implant-supported prosthesis. Methods: Ten frameworks were made of cobalt-chromium alloy (Co-Cr), simulating a three-element fixed prosthesis on two implants. Five frameworks were constructed using prefabricated cylinders, and the other five were constructed using calcinable cylinders. All frameworks were cast by the induction technique and laser-welded. Marginal misfit was measured by means of scanning electron microscopy with the frameworks subjected to the single-screw test. Twenty-five measurements of marginal fit were recorded per abutment and averaged for statistical analysis (ANOVA, α=0.05). Results: There was no statistically significant difference in marginal fit between the groups tested. The only difference found was when comparing the abutments with and without screw. Conclusion: It was concluded that there is no difference in marginal fit between frameworks cast in Co-Cr with calcinable and prefabricated cylinders using induction casting, laser-welding, and single-screw test. Key words: Dental implants; passive fit; manual rectification

Metodologia: Foram confeccionadas 10 infra-estruturas em liga de cobalto-cromo (Co-Cr), simulando uma prótese fixa de três elementos sobre dois implantes, com o auxílio de uma matriz metálica. Cinco infra-estruturas foram confeccionadas com cilindros pré-usinados. Outras cinco foram confeccionadas com cilindros calcináveis. Todas as infra-estruturas foram fundidas pela técnica de indução e soldadas a laser. As leituras do desajuste marginal foram realizadas através de microscopia eletrônica de varredura, utilizando a técnica do parafuso único, totalizando 25 medições em cada cilindro. As médias de desajuste marginal de cada cilindro foram utilizadas para a análise estatística (ANOVA, α=0,05). Resultados: Não houve diferença estatística no grau de desajuste marginal entre os grupos testados. Apenas houve diferença quando comparados os cilindros com e sem parafuso. Conclusão: Foi concluído que não há diferença de adaptação marginal entre as infra-estruturas fundidas em Co-Cr com cilindros calcináveis e pré-usinados, utilizando fundição por indução, soldagem a laser e teste do parafuso único.
