| 目的 探讨纤维桩核冠和铸造金属桩核冠在后牙牙体大面积缺损修复中的应用价值。 方法 选取需要桩核冠修复的病人98例118颗牙,经完善根管治疗后,采用随机数字表法随机分为纤维桩核冠组和铸造金属桩核冠组,两组患牙均用烤瓷全冠修复,恢复病人的美观和咀嚼功能。随访1~2年,观察两组修复效果。 结果 纤维桩核冠组成功56颗,成功率94％,失败3例,2例为桩核松动脱落,1例桩核折断；铸造金属桩核冠组成功46颗牙,成功率77％,其中,5例出现桩核松动脱落,3例桩核折断,3例牙龈不良反应,2例牙根折断。两组修复的成功率比较差异有统计学意义(χ2=7.230,P=0.007)。两组在桩核松动脱落、桩核折断、牙龈炎性反应及根折方面均差异无统计学意义(P>0.05)。 结论 纤维桩核是修复后牙牙体大面积缺损比较理想的桩核材料,临床使用安全可靠,具有推广应用价值。 |

| Objective To investigate the application value of fiber post and cast meta post core in the restoration of large area of defective molar tooth. Methods One hundred and eighteen molar tooth (from 98 patients) were treated with post crown,after root canal treatment,which were randomly divided into fiber pile nuclear crown group and cast metal pile nuclear crown group acording to the random number table methods,two groups of dental porcelain treated with full crown restoration.Followed up for 1~2 years,repairing effect in two groups were observed. Results There were 56 tooth success in fiber pile nuclear crown group.The success rates were 94%,and only three cases failed,in which two cases were pile nuclear mobility and one case was pile nuclear break.Fourty six tooth had successed in cast metal pile nuclear crown group,the success rate were 77%.Among them,there were five cases of pile nuclear mobility,three cases of pile nuclear break,three cases of gum adverse reactions and two cases of root fracture.The repair success rates were statistically significant between the two groups(χ2=7.230,P=0.007).There was no statistical significance in pile nuclear mobility,pile nuclear break,gingival inflammatory reaction and root fold (P>0.05). Conclusions The clinical applications of fiber post are more satisfactory in the restoration of large area of molar tooth defect,with safety and reliability during the clinical use,which valued for the popularization and application. |
