摘　　要：目的:探讨纯钛成品桩应用于后牙不平行根管修复的可行性和优越性。方法:选择后牙严重缺损伴有不平行根管的患牙180例,进行完善的根管治疗术后,随机分为3组,分别采用纯钛成品桩联合树脂核(A组)、纤维桩联合树脂核(B组)、镍铬铸桩核(C组)桩核材料联合烤瓷熔附金属全冠进行桩核全冠修复。分别于修复后1月、6月及12月复诊,评价3组的修复效果。结果:修复后1个月时3组成功率均为100.0%;修复后6个月、12个月时,A组成功率无变化,仍为100.0%,B组略有下降,但与A组比较,差异无统计学意义(P>0.05),而C组修复后6个月、12个月时成功率均明显下降,与B组和A组同时期比较,均有显著性差异(P<0.05)。结论:纯钛成品桩应用于不平行根管的后牙修复具有可行性和一定的优越性。AIM：To investigate the clinical effect of titanium post core in restoring posterior teeth with non-parallel root canal. METHODS：180 cases of the massive defect of posterior teeth with non-parallel root canal were selected after root canal therapy. The cases were divided into 3 groups,with 60 cases in each group. Titanium-reinforced post core （ group A） ,glass fiber-reinforced post core （ group B） and elinvar post core（ group C） were used to restore the defects. Evaluation of the clinical outcomes was performed at the 1 month,6 month and 12 month follow-up. RESULTS：After one month,the success rate of all three groups are 100. 0%. After 6 and 12 month,the success rate of group A was 100. 0%. The success rate of group B decreased a little but there was no significant difference between group B and group A. The success rates of group C at 6 month and 12 month were significantly lower than that of Group A and Group B. CONCLUSION：The titanium post is worth being promoted in restoring posterior teeth with non-parallel root canal because of its good biocompatibility and restoration outcome.
