| 目的：观察成品螺纹桩、铸造钴铬合金桩核、纤维桩修复残根残冠的临床应用效果。方法：将90 例患者90 颗残根残冠，随机
分成3 组，分别采用A 组成品螺纹桩，B 组铸造钴铬合金桩核，C 组纤维桩进行修复，并随诊18 个月后，比较3 组患者治疗后的
成功率。结果：3 组患者经过治疗后，成品螺纹桩组的成功率为73.33%，铸造钴铬合金桩核组的成功率为60.00%，纤维桩组的成功
率为96.67%，三组差异有统计学意义(P<0.005)。结论：与成品螺纹桩和铸造钴铬合金桩核相比，纤维桩具有更好的粘结性及抗折
能力。 |

| Objective: To study the clinical effect of prefabricated screw post, cast CoCr (chromium-cobalt) alloy post-core and fiber
post in the restoration of residual crown and root. Methods: 90 cases of patients (90 teeth) in our hospital were divided into three
groups randomly. Each group was restored by prefabricated screw post, cast CoCr alloy post-core and fiber post, respectively. After 18
months, all patients were examined and the success rates were compared. Results: The effects of the three groups were evaluated after
the treatment. The success of the fiber post group was 96.67% ，which was higher those that of the prefabricated screw post group
(73.33%) and the cast CoCr alloy post-core group(60.00%).It showed significant difference(P＜0.005). Conclusions: Compared with the
prefabricated screw post and the cast CoCr alloy post-core, the fiber post had better bond strength and fracture resistance. |
