“…Stress analysis showed FRC post and core to have the most similar stress pattern to natural tooth. This result is similar to other studies that have shown fiber posts in non-weakened teeth to exhibit normal tooth like stresses 19,20 . This may be due to similar modulus of elasticity which allowed the post to transmit the stresses like normal dentin and avoid areas of extreme stress concentration 21 .…”

“…Endodontic treatment causes further loss of tooth structure due to endo procedures that weaken the tooth. Extensive loss of tooth structure presents a problem in retention of coronal restoration as well as fracture proneness due to weakened state 2 . In many cases, posts combined with cores are the solution to the retention problem especially when most or all of the coronal portion is lost.…”

Aim: This study aimed to investigate the stress patterns in weakened teeth restored with three different types of post core restorations under a vertical load using the finite element method. Methods: Four axisymmetric models were created by computer software to simulate the lower second permanent premolar in different situations. Situation 1: natural unrestored tooth, 2: weakened tooth restored with fiber reinforced composite post and core, 3: weakened tooth restored with gold alloy post and core, and 4: weakened tooth restored with zirconia post and core. The models included a post and core without a crown, gutta percha, resin cement and supporting structures. Models were considered isotropic, and exhibiting complete adhesion. A vertical static load of 40N/mm 2 was applied to the occlusal surface. Von Mises tensile stresses were calculated in the model and presented in the form of a colored stress map. Results: Stress patterns in the fiber reinforced composite were closest to the stress pattern of natural tooth with most stresses found in the coronal area dissipating as they travel apically. Zirconia and gold post and cores had more stress concentration areas within the post and more apical than natural tooth or fiber reinforced composite. All post systems showed an area of stress concentration in dentin around the end of the post especially the zirconia post and core, however they were within the range of dentin tensile strength. Conclusion: zirconia posts are more likely to cause fracture in the root in weakened teeth when compared to fiber reinforced composite post and core. Fiber reinforced composite exhibits the closest biomechanical behavior to normal teeth.

“…However, using GFP in enlarged roots can be a challenge since the post is not completely adapted at coronal level. The thick layer of resin cement in this condition increases the risk to failure as a consequence of debonding or decementation (6).…”

This study evaluated the stress distribution in endodontically treated teeth, weakened (W) or not weakened (NW), restored with different materials of prosthetic crown using 3D-FEA. Models of a maxillary canine were constructed based on micro-CT images and divided into the groups: G1 (control) -sound tooth; G2 to G7 -endodontically treated teeth restored with glass fiber post (GFP); which G2 to G4 simulated NW root and G5 to G7 simulated W root. For crown material the teeth were restored with: G2 and G5: metallic coping and ceramic veneering, G3 and G6: zirconia coping and ceramic veneering, G4 and G7: alumina coping and ceramic veneering. Load of 180 N was applied at the incisal third of lingual surface at 45º. Models were supported by the periodontal ligament (x=y=z=0). The von Mises stress (VMS) values were calculated. The W teeth presented higher VMS at coping when compared to NW teeth and group G1 showed lower VMS value. For crown material, for both W or NW teeth, increasing VMS was found at metallic, zirconia and alumina coping, respectively. Metallic coping showed a better performance despite its unfavorable esthetics, suggesting as an appropriate material for prosthetic restoration of endodontically treated teeth.

“…The most common mode of failure for FRC posts is still loss of retention e.g. debonding from the post space 25,26) . Besides the difficulties of light transmission when luting FRC posts, there are many other problems related to the bonding of FRC posts.…”

The aim of this in vitro study was to explore light transmission through an individually formed fiber-reinforced composite (FRC) post compared with two prefabricated FRC posts. Three different glass FRC posts from different manufacturers were used: two groups included prefabricated glass FRC posts (RelyX and GC Fiber Posts) and one group consisted of individually formed E-glass FRC posts with semi-interpenetrating polymer network (semi-IPN) polymer matrix (everStick Post). Various lengths of posts and lightprotected cylinders were made. The specimens were light-polymerized on the test tray of a light radiance testing device (MARC Resin Calibrator). Light transmission in the direction of fibers was registered. Light transmission decreased with increasing post length (p≤0.001; ANOVA) up to 12 mm in all post groups. The individually formed FRC post showed highest light transmission in all cylinder lengths (p<0.001) compared to prefabricated FRC posts, which could benefit polymerization of post material and luting cement.
