“…In the present study, the survival rate from overall fracture in ETT restored with full‐coverage crowns was higher than those restored with resin composite restorations. The outcome was consistent with the results of other studies that showed that ETT with a significant loss of tooth structure should be restored with crowns …”

“…ETT are weakened by the loss of tooth structure from dental caries, tooth fracture, or pre‐existing restoration, but not from endodontic procedures . With a significant loss of tooth structure, ETT should receive a cuspal‐coverage restoration to prevent unrestorable fracture . ETT restored with crowns within 4 months had a significantly higher survival rate than ETT with delayed restoration placement …”

Aim The aim of the present study was to investigate survival rates from fracture of endodontically treated posterior teeth (ETT) restored with or without crowns with recall periods of up to 5 years. Methods ETT with single‐unit crown or resin composite restorations were studied based on the inclusion criteria. Restoration, tooth structure loss, adjacent teeth, fracture, and restorability were recorded. Survival rates from fracture were calculated, and risk factors were identified. Results Overall, survival rate of ETT with crowns (92.2%) was significantly higher than resin composites (77.4%) (P < 0.05). ETT with one or two surface loss/es and two adjacent teeth had a high survival rate of 86.9%, which was not significantly different to ETT with crowns (P ≥ 0.05). Restoration and adjacent teeth were identified as significant factors. The majority of fractured ETT with resin composites were restorable, whereas those with crowns were unrestorable. Survival rates from unrestorable fracture were not significantly different between the crown (93.1%) and resin composite (96%) (P ≥ 0.05). Conclusions The survival rate from the fracture of ETT restored with crowns was significantly higher than ETT restored with resin composites, but was not significantly different to ETT with one or two ETT with one or two surface loss/es and two adjacent teeth. ETT restored with resin composites had mostly restorable fracture, whereas ETT with unrestorable fracture were similar between the two restorations.

“…Hence, dental composites are most often the material of choice in the restoration of endodontically treated teeth 6) . Also, finishing the therapy in one session is considerably more comfortable for the patient 18) . Further, the finantial aspect plays a very important role in the choice of reconstruction, and longer chair time or laboratory procedures elevate the costs of the intervention 19) .…”

“…Most of the available in vivo, in vitro and FEA literature on the survival and success of postendodontic restorations investigates the classical crown restoration, so the results cannot be fully comparable to the present study. However, certain in vivo studies showed equally good or better performance of direct composite restorations as compared to metalocramic crowns after a 5 and 9-year follow-up, respectivelly 18,22) . Cusp reduction was the most influential factor in the maximum von Mises stress value changes in the enamel.…”

Influence of restorative procedures on endodontically treated premolars: Finite element analysis of a CT-scan based three-dimensional model

An endodontically treated tooth with mesial-occlusal-distal (MOD) cavity is often restored with composite resin. Palatal and buccal cusp reduction (MODP, MODPB), and/or fiber-reinforced composite posts (P), are used in an attempt to improve the longevity of the restoration. The aim of this study was to determine the effects of these procedures on von Mises stress values and distribution in dental tissues and restorative materials using finite element analysis. Based on CT scans of an extracted second upper premolar, six 3D endodontically treated tooth models (MOD, MODP, MODPB, MOD+P, MODP+P, MODPB+P) were created. Each model was subjected to a summary force of 150 N on the occlusal surface simulating the normal biting pattern and maximal von Mises stresses were calculated. MODP seems to reduce von Mises stress values in dental tissues and P seems to transfer some of the stresses from dental tissues to the composite filling.
