摘　　要：目的:比较两种桩核材料用于磨牙冠缺损的修复效果。方法:临床选择45例患者共61颗患牙的磨牙缺损,按照随机数字表法分为两组,分别进行铸造插销式分体桩核和银汞-银粉玻璃离子桩核金瓷冠修复,3年后对修复效果进行评价。结果:铸造插销式分体桩核组共20例患者25颗患牙,未出现桩冠脱落、根折和桩折等,成功率100%;银汞-银粉玻璃离子桩核组共25例患者36颗患牙,出现桩折1颗患牙,未出现桩冠脱落、根折等,成功率97.2%。两组成功率比较差异无统计学意义(P>0.05)。结论:对于重度磨牙缺损病例,选用铸造插销式分体桩核和银汞-银粉玻璃离子桩核金瓷冠修复均可,但对于患者希望减少就诊次数、经济费用以及临床操作简便的,选用银汞-银粉玻璃离子桩核更合适。Objective：To compare the effect of two post and core materials in restoration of severely defected molars.Method：Forty-five patients with 61 severely defect molars were randomly divided into two groups,and they were treated with cast metal post-core and amalgam-silver alloy-glass ionomer post-core respectively.The repair effect after 3 years was evaluated.Result：In the 20 patients with 25 teeth in cast metal post-core was no crown off,root fracture and pile fracture,the success rate was 100%;In the 25 patients with 36 teeth in amalgam-silver alloy-glass ionomer post-core group,one tooth appeared post fracture,no shedding,crown root fracture,the success rate was 97.2%.There was no significant difference between the two groups（P0.05）.Conclusion：For severe molar defect cases,both cast metal post-core and amalgam-silver alloy-glass ionomer post-core can be used,but amalgam-silver alloy-glass ionomer post-core cost less.
