“…In the study by Jindal et al 2 experimental groups with shorter post lengths showed lower fracture resistance. The study by Abdulmunem et al 52 reported that the type of luting cement affects the fracture resistance in ETT restored with titanium and fiber posts. Specifically, resin cement gives higher fracture resistance than glass ionomer cement 3,9 .…”

Purpose The fracture resistance of dental post systems is influenced by the material of the post. The purpose of this systematic review and meta‐analysis was to assess if there is a difference in fracture resistance between prefabricated dental titanium posts and fiber posts. Methods An online electronic search was performed using the PubMed, Scopus, and Web of Science databases for in vitro studies published from 2010 to 2020 in English. The retrieved eligible studies that compared the fracture resistance of titanium and fiber posts on human teeth were selected. The pooled standardized mean difference (SMD) with a 95% confidence interval was calculated. In addition, the trial sequential analysis (TSA) was performed to test if the available studies are sufficient to make conclusive evidence. Results Of the 1165 retrieved studies, 17 studies were included in the qualitative analysis, while 16 studies were included in the quantitative analysis. Because of the high heterogeneity among studies, data from 10 studies were pooled and submitted to TSA. A total of 852 teeth were evaluated for fracture of the posts in 27 independent comparison groups. The pooled effect of the residual studies revealed no significant difference between titanium and fiber posts (SMD = –0.12; 95% CI = –0.30, 0.06; p = 0.20). Results of the TSA revealed no conclusive evidence. Conclusions The results of the current evidence revealed no significant difference between fiber and titanium posts. The evidence is insufficient, and more standardized in vitro studies are required.

“…Two models were compared, one featuring an inlay restoration and the other an onlay restoration, with both restorations having the same geometry for the cervical cavity. Though some finite element studies addressing the biomechanical behavior of the cavity design on teeth restored with inlay or onlay ceramics have been published [19,22,[41][42][43][44], the work presented here is, to our knowledge, the first nonlinear analysis presenting the results of damage analysis.…”

The main purpose of this work was to analyze the stress distribution in premolars restored with indirect IPS Empress® CAD onlays or inlays. The three-dimensional geometry of a human first premolar was created using modeling software. The tooth fixation system was simulated through box geometry, comprising a cortical bone layer with 2 mm of thickness over a layer of trabecular bone with 15 mm of thickness. The tooth had the following approximated crown dimensions: 10.35 mm buccolingual length; 7.1 mm mesiodistal width; and 7.0 mm cervico-occlusal height. The mesio-occluso-distal (MOD) cavity preparations followed the suggestions available in the literature. The cement geometry was modified to include cohesive zone models (CZM) to perform the adhesive joint’s strength prediction. The loading body was created assuming contact between the food bolus and the tooth surface. Numerical solutions were obtained by performing static analysis and damage analysis using the finite element method. Von Mises stress values generated in the ceramic inlay restoration ranged from 1.39–181.47 MPa, which were on average 4.4% higher than those of the onlay ceramic restoration. The fracture strength of the onlay restoration was about 18% higher than that of the inlay restoration. The onlay design seems to contribute to higher homogenization of the adhesive resin cement strain and higher tooth structure protection.

“…Several kinds of research about dental cement have been done previously [11][12][13]. For example, Abdulmunem et al investigated the effect of two variants of dental cement on fracture resistance of endodontic-treated teeth with post-core systems [11].…”

The aim of the study was to evaluate the influence of resin cement material types on tooth with endocrown and onlay restorations. The first molar was scanned using Micro‐CT and underwent a modelling process to obtain the 3D model for computational simulation. Eight models were simulated in the current study with two loading conditions (720N vertical load and 200N oblique load), two types of restoration (onlay and endocrown restorations), and two resin cement variants (dual‐cure resin cement and light‐cure resin cement). The tooth with onlay restoration showed a significant stress reduction (up to 70%) when using light‐cure resin cement compared to dual‐cure resin cement. In contrast, types of cement did not affect stress distribution in the tooth with endocrown restoration. The current study found that dual‐cure resin cement was preferable in Endocrown and Onlay restorations, due to dual‐cure resin cement provided better bond strength compared to light‐cure resin cement.
