Influence of Post Length, Post Material, and Substance Loss on the Fracture Resistance of Endodontically Treated Teeth: A Laboratory Study

Fracture resistance of maxillary premolars restored with different endocrown designs and materials after artificial ageing

“…The post materials were formerly believed to have a direct impact on the teeth mechanical behaviour and mode of failure. The recent studies reported that the post materials showed no influence on the fracture strength [42] nor the mode of failure [43]. Nowadays, the most important factors are the ferrule presence [44] and the post bonding condition [45].…”

Fracture Resistance of Titanium and Fiber Dental Posts: A Systematic Review and Meta‐Analysis

“…This finding is consistent with the results of other studies. 4,9,21,[23][24][25][26][27][28] However, the results of our review do not appear to be consistent with another systematic review 46 that investigated the fracture resistance of cast and fiber posts. This is because the included studies were RCT and most of them used Ni-Cr alloy for cast post.…”

“…2,3,7 Opposite findings have also been reported. [15][16][17][18][19][20][21][22] Meanwhile, some studies concluded no significant difference between the two post materials. 4,9,21,[23][24][25][26][27][28] Dietshi et al, 29 I of their systematic review, emphasized the use of post and core materials that have physical properties similar to the natural dentin because of, according to the review, the limitations of the currently followed adhesive procedures.…”

The results of a systematic review by Theodosopoulou et al 30 revealed that the success rate of glass fiber posts was significantly better than prefabricated metal posts and moderately better than quartz fiber posts.…”
