Post-retained single crowns performance linked to amount of coronal structure

shutterstock_134851484

This review of post-retained crowns on endodontically treated teeth included 9 RCTs. Findings suggest that that the number of remaining coronal walls and the use of posts are key factors for the success/ survival of these restorations. However the quality of the available evidence is low.

This review of the impact of eugenol-based sealers on the bond strengths for fibre posts cemented to root canals included 9 in-vitro studies. The eugenol-based sealants reduced the bond strength by 0.8 MPa.

Root canal posts: review suggests no difference in root fracture incidence between metal-and fibre posts

This review compared root fracture rates of metal and fibre root canal posts and found not difference. While 14 studies were included only 7 were randomised trials and all were of low quality so higher quality studies are needed.

Study suggests increased failure risk in root treated teeth with less coronal structure restored with fibre post

The aim of this study was to assess whether the amount of residual coronal structure and the type of cement used for fibre post luting (self-adhesive cement vs. composite core material) affected the four-year survival of root-filled premolars. Patients requiring endodontic treatment and single-unit crown restoration of premolars were eligible.  Patients were divided into two [read the full story…]

Similar performance from glass fibre–reinforced epoxy resin posts and titanium posts in endodontically treated teeth at 7 years

Yesterday (Dental Elf 14th Jan 2012) we looked at a review that compared cast and fibre posts in-vitro. Here we are looking at a trail that compares the use of more flexible, dentine-like (low Young modulus) glass fibre–reinforced epoxy resin posts (GFREPs) with rather rigid, stiff (higher Young modulus) titanium posts (TPs) in order to [read the full story…]

Review of in-vitro studies shows greater fracture resistance for cast posts

shutterstock_25133602 - Cast post & core on model

Endodontically treated teeth (ETT) are considered to be more brittle and subject to fracture. Posts are frequently used to restore ETT and use of the appropriate post material is considered important to a successful restoration.  The aim of this review of in-vitro studies was to compare the fracture load of ETT restored with cast of [read the full story…]
