玻璃纤维桩树脂核修复末端第二磨牙残冠临床效果评价

Clinical assessment of repair of free second molar residual crowns by glass fiber post and resin core

用玻璃纤维桩树脂核（观察组）和铸造钻铬合金桩核（对照组）分别修复末端第二磨牙残冠各37颗。1-5年成功率,观察组分别为100%、100%、91.9%、86.5%、81.1%;对照组分别为97.3%、91.9%、83.8%、81.1%、73.0%,在5个时间点,2组桩核冠修复成功率差异均无统计学意义。

37 free second molar residual crowns were repaired by glass fiber post and resin core（GF group）,and another 37 by cobalt chromium alloy casting post and core（CCA group）.The success rate of 1 -5 years of GF group was 100%,100%,91.9%,86.5%and81.1%;that of CCA group 97.3%,91.9%,83.8%,81.1%and 73.0%,respectively（P〉0.05）.
