Rebuilding teeth after root canal treatment. Choosing between a ...posts and cores - What are they? When are ... The flexural strength of dentin (the hard, calcified tissue that makes up the bulk of a tooth) is likely reduced by the various chemical agents frequently used during the cleaning phase of root canal therapy (Eliyas 2015). ... The following survival rates were observed for teeth with the following types of restorations: cast restoration (dental crown) - 92%, amalgam restorations ("silver" filling) - 67%, composite restorations (tooth bonding) - 35%.
Root Fortification - Journal of EndodonticsOne group has found that a thick intermediate composite layer between the root wall and a thin metal post could significantly increase the fracture resistance of weakened roots compared with a custom cast metal post bonded to the enlarged canal (75, 76). The idea of the thick ... This anatomically thin region represents a functionally graded zone where the enamel and dentin close to the interface have slightly different microstructures and properties than the more distant bulk phases.
Restoration of the Endodontically Treated ToothThe potential for root weakening from post preparation tends to outweigh any possible benefits. Uncrowned anterior teeth with access restoration and no post provided greater resistance to fracture under cyclic loading in vitro than even crowned teeth with post-core restorations.40-42 Optimally bonded composite restorations are appropriate. Intra-coronal and/or extra- coronal bleaching can be considered for the relatively sound, but discoloured, anterior tooth to avoid the need.
MultiCore & Tetric EvoCeram Bulk Fill - Ivoclar VivadentFOR THE MATRIX TECHNIQUE. MultiCore Flow. Self-curing core build-up composite with light-curing option. Dentists who like to use the matrix technique to fabricate core build-ups will appre- ciate the flowable MultiCore Flow composite. MultiCore Flow can also be used for the adhesive cementation of glass-fibre reinforced root posts, e.g. FRC postec Plus. Practical automix tip. The automix tip and the intraoral tip ensure excellent mixing of the contents and precise application.
In vitro evaluation of the shear bond strength between fiber posts ...11 Jul 2016 ... Sixty #3 FP (Exacto Translúcido) were divided into six experimental groups (n = 10), according to the surface treatment used: G1Filtek Z250; G2Filtek P90; G3Filtek bulk fill restorative; G4Scotchbond Universal adhesive + Filtek ... The depth polymerization capability and lower polymerization shrinkage of this group of composite resins could aid in obtaining the most root-wall-fit personalization of the fiber post within the customization post technique,

A small irregularity remains at the CEJ and is treated with a composite restoration.
Influence of Different Restorative Techniques on the Strength of ...14 May 2012 ... Crowns of 100 single-rooted teeth were sectioned and 10 roots were kept as negative control group (Group 1). Remaining roots were instrumented and divided into one and positive control group of 10 samples (Group 2) and 4 experimental groups of 20 samples each. Group 3: roots were obturated with gutta-percha; Group 4: roots were restored with gutta-percha, composite, and glass fiber post; Group 5: roots were obturated with Resilon; Group 6: roots were ...

Ceramic Veneers and Root Coverage - StyleitalianoImg. 2 The old crowns were removed and a new composite core build up was done for 1.1. The rest of the teeth were minimally prepared. All Class V lesions were restored with flowable composite, Filtek Supreme, 3M ESPE. Fig. 3. Img. 3 The Class V restorations were treated as a part of the tooth while preparing the teeth. TIP#1: once the Class V restorations are done the final curing cycle should be carried out with a water soluble oxygen blocking gel that eliminates the oxygen ...
