Fracture resistance and primary failure mode of endodontically treated teeth restored with a carbon fiber-reinforced resin post system in vitro.

摘要: Purpose This study was undertaken to characterize the fracture resistance and mode of endodontically treated incisors restored with cast post-and-core, prefabricated stainless steel post, or carbon fiber-reinforced composite post systems. Materials methods Ten teeth each technique were subjected a compressive load delivered at 130-degree angle long axis until first sign failure noted. The recorded. Results loads registered in three groups not significantly different. Between 70%, 80% from any displayed fractures that located above simulated bone level. Conclusion use posts did change central compared metallic posts.
