This study examined the effect of four different post systems, Cast Post, Para Post, Flexi-post and Fil Post, on the fracture resistance of crowned endodontically treated teeth. The Flexi-post and Para Post groups showed significantly higher resistance to fracture than the others. Horizontal root fractures were seen in the prefabricated post groups compared with vertical root fractures in the Cast Post group. Findings of this study suggest that the choice of prefabricated post systems is important in determining maximum resistance to fracture in teeth that have been endodontically treated.
本研究考察了四种不同的桩系统，即铸造桩、帕拉桩、弹性桩和菲尔桩，对经根管治疗后带冠牙齿抗折性的影响。弹性桩组和帕拉桩组的抗折性明显高于其他组。与铸造桩组出现的垂直根折相比，预成桩组出现了水平根折。本研究结果表明，在确定经根管治疗牙齿的最大抗折性时，预成桩系统的选择很重要。
