In Vitro Fracture Resistance and Deflection of Pulpless Teeth Restored with Fiber Posts and Prepared for Veneers

Effect of Fiber Post and Cusp Coverage on Fracture Resistance of Endodontically Treated Maxillary Premolars Directly Restored with Composite Resin

“…Therefore, it seems that even without fiber post placement, it is possible to dissipate occlusal forces in a wide surface area as a result of micromechanical adhesion, rendering the tooth more resistant against forces. However, in contrast to our results, it has been reported that fiber posts provide significantly higher fracture resistance in incisors with indirect all-ceramic crowns or veneers (23,24). In another study, Soares et al (6) showed that glass fiber posts do not restore the lost fracture resistance in endodontically treated mandibular premolars with major tooth structure loss and actually reduce fracture resistance in cases of moderate structure loss when the tooth is restored with direct composite resin.…”

“…3). This finding agrees with those from a study by D'Arcangelo et al (21) in which similar fracture strength values were reported for intact teeth and those restored using fiber-reinforced bonded posts. In this case, the tooth fixed to the alveolar socket behaves like a cantilever beam, with tensile stresses situated in the palatal aspect and compressive stresses in the buccal aspect.…”

Fracture Resistance of Teeth Restored with Post-retained Restorations: An Overview

“…Providing a crown with adequate ferrule has more influence on the fracture resistance of dowel-restored teeth than factors related to post and core materials and designs (134,169). D'Arcangelo et al (170,171) suggested the use of fiber posts when veneer restorations were used to restore endodontically treated teeth because they found that fiber posts increased the fracture resistance of endodontically treated teeth prepared for or restored with composite or porcelain veneers.…”
