2种桩核材料的临床应用

Clinical use of two kinds of post-core materials

目的 探讨2种桩核材料的临床效果。方法 选择了588名牙体缺损患者805颗患牙,采用螺纹桩加树脂核心或铸造桩核制作桩核后,再进行冠桥修复并进行随访观察。结果 螺纹桩加树脂核心系统失败率较高,成功率仅为69.9％;铸造桩核系统修复成功率较高,达95.3％。结论 铸造桩核的远期修复效果较螺纹桩核好,值得推广。

Objective This study is to determine the clinical use of two kinds of post-core systems. Methods 805 defective teeth of 588 patients were chosen. These teeth were restored with screw post-resin core system or cast post and core system, then restored with crown or bridge and the clinical effect was observed periodically. Results The success rate of screw post-resin core system was 69.9%, while the rate of cast post and core system was 95.3%. Conclusion The long-term clinical effect of cast post and core system is better than screw post-resin core system, which is worthy of wide use.
