不同桩核全冠修复磨牙残冠疗效对比

Residual crowns with different pile nuclear crown molars,long-term curative effect contrast

目的:对比分析不同桩核全冠修复磨牙残冠的近、远期疗效。方法:选择完善根管治疗的215颗磨牙残冠,利用铸造桩核全冠、螺纹桩树脂核全冠与螺纹银汞合金核全冠实施磨牙残冠修复,并观察其治疗结果。结果:铸造桩核全冠修复组1年内无失败例数,5年的失败率是1.23%,明显比其他两组低,差异有统计学意义(P<0.05);螺纹桩树脂核全冠修复组与螺纹桩银汞合金核全冠修复组之间的失败率均较大,差异无统计学意义(P>0.05),但其时间差异有统计学意义(P<0.05)。结论:在不同桩核全冠修复的磨牙残冠中,螺纹桩核全冠修复不如铸造桩核全冠修复的近远期疗效好。

Objective Comparative analysis of near,long-term effect of residual crowns with different pile nuclear crown molar.Methods The perfect 215 molar residual crown and root canal therapy,casting post core and crown,post and light-cure resin crown with screw amalgam crown of molar residual crown repair,and observe the results of treatment.Results Casting post core and crown group of 1 years without failure cases,failure rate at 5 years was 1.23%,significantly lower than the other two groups,the difference was statistically significant（P〈0.05）;between the screw pile nuclear crown repair resin screw pile group and silver amalgam restoration of crown group were higher failure rate,difference was not statistically significant（P〉0.05）,but there was a statistically significant difference（P〈0.05） time.Conclusion In the residual molar crown of different pile nuclear crown repair,screw pile nuclear crown repair as casting short-and long-term effect of pile nuclear crown repair.
