“…Cohen et al, reported that the glass ionomer demonstrated a lower fatigue resistance than composite and silver amalgam which is similar to the results of our study [15]. Bonilla et al, compared five core materials and concluded that titanium-reinforced composite resin, had greater resistance followed by amalgam and gic but according to our study the Miracle Mix had more resistance followed by Composite and reinforced GIC [16].…”

“…It has to be pointed out that the results shown in this work have to be taken with care, because of the S-N curves that have been estimated. The magnitude and direction of the force applied are comparable with values reported in the literature for premolars [21][22][23] . The analysis of the factor of safety (under a static load) revealed that the failure would occur at the crown, in the area where the load is applied.…”

“…The study was undertaken with a model of a maxillary premolar restored using the ParaPost Fiber White and the ParaPost Stainless Steel, and with the definitive crown added. A 50 N load was applied to the palatal side of the tooth at a 30° angle to the radicular axis, in the vestibular direction, in order to simulate real biting force's direction [21][22][23] . An unfavourable situation of malocclusion has been considered, i.e., the force was applied to the buccal incline of the palatal cusp.…”

Premolars restored with posts of different materials: fatigue analysis

et al. 2011

Previous works studied the effect of the material and the dimensions of the post on the biomechanical performance (fracture strength and stress distribution) of restored teeth, under static loads. The aim of this work was to study the effect of the post material (glass fibre and stainless steel) on restored teeth, which have the final crown, under dynamic conditions. The use of a biomechanical model, including a fatigue analysis from FEA, is presented as a powerful method to study the effect of the material of the intraradicular post. The inclusion of the fatigue analysis allows for a more realistic study that takes into account the dynamic nature of masticatory forces. At the same time, the results obtained are easier to interpret by both dentists and mechanical engineers. No differences were found, with the load and number of cycles considered, between glass fibre and stainless steel as material for the intraradicular post used in premolars restorations.

“…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) . On fiber posts, they are in essence composite materials.…”

Fatigue resistance and structural integrity of different types of fiber posts

et al. 2008

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.
