The adhesion between prefabricated FRC posts and composite resin cores: microtensile bond strength with and without post-silanization.
OBJECTIVES Aim of the study was to measure the adhesion between two types of translucent prefabricated FRC posts (FRC Postec, Ivoclar-Vivadent, FRC; Light-Post, RTD, LP), and two types of flowable composites used as core materials (UnifilFlow, GC, UF; Tetric Flow, Ivoclar-Vivadent, TF), with or without the application of a silane (Monobond-S, Ivoclar-Vivadent, S) on the post surface. METHODS ...
متن کاملComparison of the Fracture Resistance of Endodontically Treated Teeth Restored with Prefabricated Posts and Composite Resin Cores with Different Post Lengths
OBJECTIVE This study evaluated the fracture strengths of endodontically treated teeth restored with prefabricated posts with different post lengths. MATERIAL AND METHODS Thirty freshly extracted canines were endodontically treated. They were randomly divided into groups of 10 teeth and prepared according to 3 experimental protocols, as follows; Group 1/3 PP: teeth restored with prefabricated ...
متن کاملMicro-Shear Bond Strength of Indirect Composite Resin to Three Different Computer-Milled Cores After Thermocycling
Background and Aim: The aim of this study was to evaluate the micro-shear bond strength of an indirect composite resin to three different types of cores. Materials and Methods: In this in-vitro study, 14 blocks (5×5×2 mm) were designed and milled by computer from cobalt-chromium (Co-Cr) alloy, zirconia, and polyether ether ketone (PEEK). Each sample was treated according to the manufacturer’s ...
متن کاملEffect of the ferrule on fracture resistance of teeth restored with prefabricated posts and composite cores.
BACKGROUND The ferrule effect in root treated teeth requiring cast posts and cores has been shown to greatly improve fracture resistance. Studies have also shown that in the case of a cast post and core, the longer the ferrule, the greater the fracture resistance. However few studies have considered the effect of different ferrule designs on prefabricated post and composite core systems. AIM ...
متن کاملComparison of Thermal Stress on Various Restorative Post and Core Materials Generated by Oral Temperature Changes Using Three Dimensional Finite Element Analysis
Background and Aim: The purpose of this study was to compare thermal stress on various restorative post and core materials generated by oral temperature changes using three dimensional finite element analysis. Materials and Methods: Three dimensional model of a mandibular right first premolar restored with a metal-ceramic crown and a dowel – core system was constructed. The thermal load applied...
