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 observe the clinical effect of finished screw pile, cast cobalt-chromium alloy post core and fiber post to repair residual root. Methods: Ninety residual root crowns of 90 patients were randomly divided into three groups, respectively. Group A finished screw pile, Group B cast cobalt-chromium alloy post, and Group C fiber post were repaired. After 18 months of follow-up, Three groups of patients after treatment compared the success rate. Results: The successful rate of finished screw pile group was 73.33%, the successful rate of casting cobalt-chromium alloy post-core pile group was 60.00%, and the success rate of fiber pile group was 96.67%. The differences among the three groups were statistically significant Significance (P <0.005). CONCLUSIONS: Compared with the finished screw pile and the cast cobalt-chromium alloy post core, the fiber post has better cohesiveness and bending resistance.
