Anthogyr不锈钢根管桩在后牙残冠修复中的应用

The application of Anthogyr root-canal stainless steel post in molar residual crown restoration

目的比较Anthogyr不锈钢根管桩与玻璃纤维桩在后牙残冠即刻桩核修补、烤瓷永久修复后的实际疗效。方法 122例患者共130颗后牙随机分成两组,每组65颗,分别采用Anthogyr不锈钢根管桩和玻璃纤维桩修复患牙,且均采用光固化瓷化树脂修补残冠并烤瓷冠修复,对其操作时间、成功率进行对比。结果经2年随访,不锈钢桩组出现3例桩弯曲移位,其操作时间明显短于纤维桩组(P<0.01);但两组总成功率差异无统计学意义(P>0.05)。结论 Anthogyr不锈钢根管桩与玻璃纤维桩,疗效相近,前者设计独特,固位好,操作更便捷,成本更低廉,在后牙残冠修复中值得大力推广应用。

Objective To compare the practical results of two post cores （ Anthogyr root-canal stainless steel post and glass-fiber post）through the methods of instantly restoring the residual crown and then restoring the residual crown for permanent ceramic crown. Methods One hundred and twenty-two patients with 130 tooth were randomly divided into two groups, every group was 65 tooth. Two methods （Anthogyr root-canal stainless steel post and glass-fiber post） were used for restoring the molar residual crown respectively, and every group was treated through light-cure tetric ceram repairing the residual crown and then then restoring the residual crown for permanent ceramic crown. The operation time and the success rate were compared. Results Two years follow-up showed, in the group of Anthogyr root-canal stainless steel post three stainless steel post were curved and displaced, and the operation time was shorter than that of group of glass-fiber post （P 〈 0. 01 ）. But there was no statistical significance in the success rate between the two kinds of posts （P 〉 0.05）. Conclusion The anthogyr root-canal stainless steel post and the glass-fiber post have similar curative effect. But the ：Former which has advantages of special design, hard retainer, simple operation and lower cost, is worth popularizing and applying.
