“…Fatigue is considered as one of the main causes of structural failure in restorative dentistry [21][22][23][24] . It has been reported that dental restorations fail more frequently under cyclic loading tests that are well below the ultimate flexural strength of these materials, versus the application of a single, relatively higher, external force 25) . Fatigue tests can reveal the resistance level of each type of post under cyclic loading, which simulates the normal occlusal and masticatory function 16,26,27) .…”

The study aimed at assessing and estimating the fatigue resistance of different fiber posts and to observe their ultrastructures through SEM. Six types of fiber posts were used: GC Fiber Post (Group 1), ParaPost Fiber White (Group 2), FibreKor (Group 3), DT Light-Post radiopaque (Group 4), FRC Postec (Group 5), and Luscent Anchors (Group 6). Ten out of 15 posts within each group were used for the fatigue test, and the other five were processed for SEM evaluation. The fatigue test revealed that Groups 1, 4, and 5 performed better than all the other groups, and that their performance differed significantly from the other tested groups from a statistical standpoint. For SEM analysis, Groups 1, 4, and 5 also obtained better results. Through correlation analysis, an absence of correlation between fatigue resistance and structural characteristics suggested that the latter reflected more of the divergence inherent in the manufacturing process of fiber posts.

“…Como promedio es conveniente que el orificio para el poste sea de unos 2 mm de diámetro. Se puede mejorar la retención a expensas del diámetro del diente pero el riesgo de fractura aumenta notablemente (2,(5)(6)(7).…”

El propósito del presente estudio fue determinar la resistencia a la fractura frente a cargaestática transversal de piezas dentarias tratadas endodonticamente, restauradas con espigomuñóncolado, postes de fibra de carbono(C-Post®, ©Bisco Inc) y postes de aleación de titanio(Parapost®, ©Coltène/Whaledent Inc.). Se utilizó el adhesivo All Bond 2® (©Bisco, Inc) comomaterial adhesivo y el cemento de resina Duolink® (©Bisco Inc) para cementar los postes. Laprueba de anova unifactorial encontró que las piezas dentarias restauradas con espigo-muñóncolado tuvieron una mayor resistencia frente a carga estática transversal que las piezas dentariasrestauradas con postes de fibra de carbono(C-Post®, ©Bisco Inc) y postes de aleación de titanio(Parapost ®, ©Coltène/Whaledent Inc).

“…A expansão do revestimento foi feita pela técnica convencional da expansão térmica, utilizando-se uma célula de carga número 2 (100Kg) e velocidade de 0,5mm/min (KAHN et al, 1994;MONDELLI et al, 1980). Os corpos-de-prova receberam uma força de compressão incidindo em ângulo de 135º com o longo eixo da raiz (ângulo de 45º em relação ao plano horizontal), simulando um contato oclusal do dente antagonista em classe I de Angle (Figura 11).…”
