Effect of Cyclic Loading on Fracture Strength of Endodontically Treated Teeth Restored with Conventional and Esthetic Posts
INTRODUCTION Esthetic post and core systems were recently introduced. There are few reports regarding their behavior under cyclic loading. OBJECTIVES This study compared the effect of cyclic loading on survival rate, residual strength and mode of fracture of endodontically treated teeth restored with esthetic and direct metallic post systems subjected to mechanical cyclic loading. MATERIALS...

متن کاملFracture Resistance of Endodontically Treated Teeth Restored with Fibre or Cast Posts
The purpose of this study was to determine the fracture resistance of 4 post and core systems. 40 extracted maxillary canines (for orthodontic reason) were used for this study. The samples were divided into 4 groups, which were: Group (1) Cast post luted with Rely X ARC; Group (2) Cast post cemented with zinc phosphate; Group (3) Fibre post luted with Rely X + Filtek Z-250 as core material; Gro...
متن کاملComparison of fracture resistance of endodontically treated teeth restored with two different fiber posts
Background: The aim of this study was to determine and compare the fracture resistance of endodontically treated teeth restored with two different glass fiber posts. Materials and methods: Thirty extracted intact human premolar teeth were selected for the study. All the teeth were decoronated maintaining root length of 15mm from apex. Root canals were enlarged using protaper rotary file. Obtura...
