Evaluation of Different Post Lengths’ Effect on Fracture Resistance of a Glass Fiber Post System
OBJECTIVES The purpose of this in vitro study was to evaluate the influence of different post lengths upon root fracture resistance. METHODS 78 maxillary central teeth with similar dimensions were mounted in acrylic blocks with artificial silicone periodontal ligaments. Combinations of post lengths of 6 mm (shorter than 1/1 clinical crown length), 9 mm (1/1 clinical crown length), and 12 mm (...
متن کاملFracture Resistance of Endodontically Treated Teeth Restored by Glass Fiber Post and Carbon Post Systems
known that these teeth are generally weak because of dental structure loss, cavities, filling preparation, and root canal instrumentation. These teeth are thus rendered weak. Moreover, the decrease in the dentin moisture further lowers their strength properties, thus making them more susceptible to fractures. Therefore, it is necessary to take utmost care while selecting the most efficient way ...
متن کاملEffect of length and diameter of fiber reinforced composite post (FRC) on fracture resistance of remaining tooth structure
Introduction: Post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. Recently fiber reinforced composite posts (FRC post) have been used in the treatment of endodontically treated teeth. Because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...
متن کاملIn vitro evaluation of glass fiber post
STATEMENT OF PROBLEM Techniques and recommendations for the restoration of endodontically treated teeth have changed from the use of custom cast metal post and core system to glass fiber-reinforced (GFRC) post and composite core system. Has this latest prefabricated glass fiber reinforced post and composite core system increased the fracture resistance of teeth and reduced the incidence of unre...
متن کاملComparison of fracture resistance of bonded glass fiber posts at different lengths.
PURPOSE To evaluate in vitro the fracture resistance of quartz fiber posts for three different dowel lengths. METHODS 30 single-rooted human premolars with similar root length and diameter were endodontically treated and randomly divided into three experimental groups (n = 10) according to the post space depth created: (1) 5 mm; (2) 7 mm; (3) 9 mm. Quartz fiber posts (Endo Light post) were ce...
