OBJETIVO: Os autores estudam as características do fio de poliéster (ethibond) após o contato com o metilmetacrilato (cimento ortopédico) no laboratório de resistência de materiais. MÉTODOS: Avaliam a força necessária para a ruptura bem como a elasticidade e a deformidade provocadas durante a tração no aparelho Instron 4482. Realizam análise estatística através do teste "t-student". RESULTADOS: Não encontram diferença estatisticamente significativa entre os grupos estudados. CONCLUSÃO: Concluem que o contato do metilmetacrilato com o poliéster não acarreta mudanças na suas propriedades elásticas e de resistência à tração.
OBJECTIVE: The authors studied the physical properties of polyester thread (ethibond) following methyl methacrylate contact in a biomechanics laboratory. METHODS: Strain at rupture, elasticity and traction deformity were evaluated using an Instron 4482 machine. The student-t test was used for the statistical analysis. RESULTS: There were no statistical differences between the two groups. CONCLUSION: It is concluded that methy metacrylate contact with polyester does not affect its elastic properties and traction resistance.
