Abstract
Aim: To compare the retention and fracture resistance of three different pre-fabricated posts systems in endodontically treated anterior tooth.
Materials and Methods: Root canal treatment was performed for all the 90 samples used in the study. After the completion of obturation, post space preparation was done accompanied by post cementation. The samples were divided into three groups depending on the post cemented (Stainless Steel, Glass fiber and Ceramic post). The samples were first evaluated for retention with a help of a three-jaw chuck, which grasped the post and tried to pull it out. The force required to dislodge each post was recorded in Newtons. To evaluate the fracture resistance, the samples were subjected to compressive loads at an angle. The load required was then recorded in Newtons.
Results: The mean retention values for Stainless Steel post were significantly greater than those for Glass fiber post and Ceramic post. The mean retention values of glass-fiber post and ceramic post were not statistically different. The fracture load of the post system, it was revealed that highest mean value was seen in Stainless Steel post and was significant than ceramic post and glass-fiber post.
Conclusion: Within the limitation of this study, it can be concluded that the pre-fabricated stainless steel post exhibits a significantly higher fracture resistance and also the retention was more as compared to Glass fiber post and Ceramic post.
