TLDR
EverStick/E-glass fiber posts showed significantly higher fracture resistance than the other fiber posts and can be suggested for clinical use.Abstract:
AIM To evaluate the fracture resistance under static loading of endodontically treated teeth (maxillary central incisors) restored with carbon fiber posts, glass fiber posts, and everStick posts. The objectives of this study were to check the fracture resistance of the everStick post and compare it with glass fiber posts and carbon fiber posts and evaluated their modes of failure. MATERIALS AND METHODS An estimated 80 freshly extracted human maxillary central incisors were collected for this study. The coronal portions of 60 teeth were sectioned 4 mm incisal to the cemento-enamel junction (CEJ) and 20 teeth were left intact to be used as controls. All the samples were embedded vertically in acrylic resin blocks and the groups were divided as follows. I-control group, II-carbon fiber group, III-glass fiber group, and IV-everStick (E-glass) group. Root canal treatment was completed in all the 80 teeth of 4 groups. Control group teeth were restored with a composite. In all other teeth, post and core placement was carried out. All specimens were mounted on a test block and subjected to static loading until fracture and the mode of fracture was recorded. Statistical analysis was carried out using ANOVA to calculate the mean values of all groups. An intergroup comparison was carried out using Tukey's post hoc test. RESULTS The study showed that group I showed the highest fracture resistance followed by group IV, which is everStick post group under static loading. There was a significant difference among test groups. The main mode of fracture was repairable as there was debonding of the core in all the fiber posts. CONCLUSION Teeth of the control group showed highest fracture resistance and teeth restored with everStick posts showed higher fracture resistance than those restored with glass fiber or carbon fiber posts under static loading (p < 0.05). The principal mode of fracture was debonding of core and remaining root. Teeth restored without application of a post showed the highest fracture resistance than all other groups. CLINICAL SIGNIFICANCE EverStick/E-glass fiber posts showed significantly higher fracture resistance than the other fiber posts and can be suggested for clinical use.

TL;DR: A systematic review of the literature focused to evaluate in vitro function of prefabricated fiber posts with and without customization by additional auxillary fiber posts and composite resin on the fracture strength of wide or enlarged canals and the failure pattern showed that the use of auxiliary posts produced higher mean fracture strengths than non-customized posts.

Fracture Strength and Failure Modes of Endodontically Treated Premolars Restored with Compact and Hollow Composite Posts Subjected to Cyclic Fatigue
TL;DR: Results show that composite posts increase the mechanical stability by more than 100% compared to premolars restored with particulate composite, and glass fiber hollow posts show a good trade-off between strength and a favorable type of fracture.

Finite element analysis of a glass fibre reinforced composite endodontic post
TL;DR: In this work the mechanical response to external applied loads of a new glass fibre reinforced endodontic post is simulated by finite element (FE) analysis of a bidimensional model to avoid edges that could act as undesired stress concentrators.

Fibre-based post systems: a review
TL;DR: A review of published literature examining fibre-based endodontic post systems indicated that laboratory evidence was contradictory and could not be used to inform practice reliably and controlled prospective clinical trials evaluating fibre- based posts should be undertaken to inform use for clinical practice.

A literature review on the prosthetic treatment of structurally compromised teeth.
Annika Torbjörner,Bo Fransson +1 more
TL;DR: Favorable occlusal prosthesis design is probably more important for survival of structurally compromised endodontically treated teeth than is the type of post used, and the literature points to nonaxial forces as a risk for fatigue fracture of teeth, cement, and restorative material.

In vitro evaluation of a carbon fiber post
TL;DR: There were no significant differences in the amount of force required to produce failure among the three groups with different posts and a composite build-up, and the group restored with the carbon post had no root fractures, whereas there were five fractures in each of the parallel and tapered post groups.

TL;DR: Fiber posts show more homogeneous stress distribution than metallic posts, and the post material seems to be more relevant for the stress distribution in endodontically treated teeth than the posts' external configuration.
