摘　　要：目的了解前磨牙残根单冠与联冠修复的疗效,选择优良的前磨牙残根修复方法,为临床实践提供分析依据。方法将我科收治的前磨牙残根患者176例分为单冠修复组与联冠修复组,分别采用桩核单冠与邻牙联冠两种方法进行修复,通过修复后的随访观察各自的疗效,并进行比较分析。结果所有患者修复后均获得随访,随访时间2～4年。单冠修复组成功率为82.8%(77/93),联冠修复组成功率为93.5%(101/108),两组成功率比较有显著性差异(P<0.05)。结论联冠修复组的成功率显著高于单冠修复组,值得临床进一步推广应用。修复前必须严格把握其临床适应证,有利于获得更高的成功率。Objective To find out the therapeutic effects of single post-core-crown and combined crown applied to restoration for residual root of premolar teeth,select high quality repair method for residual root restoration of premolar teeth,and provide analytical basis for clinical practice.Methods 176 premolar residual root patients treated in our department were divided into single crown group and combined crown group,the residual roots were repaired by single post-core-crown and combined crown,therapeutic effects were observed by follow-up and were comparative analysised.Results All patients were followed up for 2 to 4 years after the repair.The repair success rate of single crown group was 82.8%（77/93）;combined crown group was 93.5%（101/108）.There was a significant difference in the two groups（P0.05）.Conclusions The success rate of combined crown group was significantly higher than single crown group,worthy of further clinical application.Before restoration its clinical indications must be strictly holded,and a higher success rate was conducive to obtained.
