摘　　要：目的比较冠延长或未运用冠延长术的龈下冠折前牙不同桩核修复方式的临床效果。方法将80例患者126颗牙冠严重缺损或外伤冠折的前牙,按是否运用牙冠延长术分为A、B 2组,A组64颗患牙,B组62颗患牙。按不同的桩核材料将A组随机分为A1、A2组,将B组随机分为B1、B2组(A1、B1组为玻璃纤维桩修复,A2、B2组为铸造金属桩核修复)。对各组临床修复效果进行分析比较。结果A、B、A1、A2、B1、B2各组治疗成功率分别为90.6%、82.2%、93.7%、87.5%、90.3%、74.2%。其中A组与B组、A1组与A2组、B1组与B2组成功率比较,差异均有统计学意义(均P<0.05)。结论牙冠延长术后纤维桩冠能有效修复龈下冠折前牙。Objective To compare the clinical effects of restoring anterior residual roots with post-core crown following surgical crown lengthening or without surgical crown lengthening.Methods Records of 80 patients with 126 anterior subgingival roots were treated with root canal treatment and restored with post-core crowns were available for review.The 126 roots were divided into 2 groups.Group A with surgical crown lengthening（n=64） and group B without surgical crown length-ening（n=62）.According to the post-core material,group A was further divided into 2 groups of A1 and A2,group B was further divided into 2 groups of B1 and B2.Group A1,B1 were restored with glassfiber post crowns and group A2,B2 were restored with cast post-core crown.All groups were conducted to evaluate and compare the clinical effects.Results The success rate of group A,B,A1,A2,B1,B2 was 90.6%,82.2%,93.7%,87.5%,90.3%,74.2% respectively.The analysis revealed statistically significant difference between the group A and B,between group A1 and group A2,between group B1 and B2（all P〈0.05）.Conclusion Glass fiber post crown restoration following surgical crown lengthening could effectively restore subgingival residual roots.
