摘要：

目的 比较前磨牙残根桩核单冠修复与残根桩核联冠修复的临床效果。方法 对2000年1月至2004年1月在哈尔滨医科大学口腔医学院修复科就诊的患者203例共238颗患牙（上前磨牙残根126颗，下前磨牙残根112颗），根据患牙残根邻牙的牙体情况分别采用烤瓷单冠修复（A组，116颗残根）、与邻牙联合烤瓷冠修复（B组，122颗残根）。结果 经过3、5年的随访观察，3年时单冠修复成功率为89.38%，联合烤瓷冠修复成功率为91.45%，两组差异无统计学意义（P ＞ 0.05）;5年时，单冠修复成功率为71.43%，联合烤瓷冠成修复成功率为88.60%，两组比较差异有统计学意义（P ＜ 0.05）。结论 前磨牙残根桩核联冠修复具有更好的临床效果。

Methods A total of 203 cases were randomly divided into two groups according to two different treatments. Among 238 teeth with residual roots of premolar ， 116 teeth were restored with single porcelain fused to metal crown and 122 teeth were restored with combined porcelain fused to metal crown. Results With 3 to 5 years of follow-up study ， single crown applied to the restoration for residual roots of premolar group had 89.38%to 71.43% success rate， combined crown 91.45% to 88.60%. The success rate had no difference in 3 years of follow-up study and no significant difference in 5 years of follow-up study with χ2 test. Conclusion Combined crown has better clinical effect than single crown used to restore residual roots of premolar .
