摘　　要：目的 比较金属铸造桩核冠与螺纹钉银汞合金桩核冠修复第一磨牙残冠的临床疗效.方法 选取第一磨牙残冠患者52例（患牙98颗）,采用随机数字表法分为A组[金属铸造桩核冠27例（患牙49颗）]和B组[螺纹钉银汞合金桩核冠组25例（患牙49颗）].经1年的随访,比较两组的成功率.结果 A组桩折断为0颗,B组桩折断为3颗,A组成功率为93.88％,B组成功率为79.59％,两组差异有统计学意义（χ2=4.346,P〈0.05）.结论 金属铸造桩核冠的固位性、抗力性、耐用性明显优越于螺纹钉银汞桩核冠,是更为理想的修复方法. Objective To compare the applicatied effect of two kinds of post core porcelain fused to metal crown for restoration of residual crown of first molar .Methods 52 patients with residual crowns of first molars （98 teeth） were selected.According to the random numerical table method ,they were divided into group A[post core crown of metal casting in 27 cases （ 49 teeth ） ] and group B [ post core crown of screw thread amalgam in 25 cases （49 teeth）].After a year of follow -up,the success rate of the two groups was compared .Results Metal casting core crown pile was broken at 0 in group A and at 3 in group B,the success rate of group A was 93.88%,and the success rate of group B was 79.59%,the difference was statistically significant between the two groups （χ2 =4.346, P〈0.05）.Conclusion The retention,resistance and durability of post core crown of metal casting is far superior to post core crown of screw thread amalgam ,and it is a more ideal repair method .
