7、价标准 85例患者进行了636个月的随访观察,观察内容包括修复体有无松动脱落,牙根有无折裂,边缘密合性及龈缘有无色素沉着。经过0.5、1、2、3年随访观察,对两种桩核的临床修复效果作对比分析,对照总结满意率。 2.2 评价效果 见表1。 表1 修复后0.5、1、2、3年的患牙复诊情况(颗) 分组附访时间年复诊牙数桩冠脱落牙根折裂牙龈着色满意数满意率% 纤维桩树脂核组0.59000090100 【摘要】 目的 比较纤维桩树脂核与金属铸造桩核修复前牙缺损的临床效果。方法 临床分别选择90颗前牙患者,年龄1962岁,已经过完善的根管治疗,分别采用纤维桩树脂核与金属铸造桩核材料制作烤瓷桩冠修复,6个月

8、3年后对修复效果进行临床对比评价。结果 经过6个月3年的随访观察,结合临床检查和X线检查,纤维桩树脂核组90颗患牙修复体良好,无松动,无折裂,烤瓷冠边缘密合。金属铸造桩核组2颗患牙根折,2颗患牙桩核松动脱落,10颗患牙龈缘出现灰色素沉着,其余78颗患牙修复良好。结论 使用纤维桩树脂核可以达到满意的修复效果,较金属铸造桩核更适于前牙缺损的修复。 【关键词】 纤维桩树脂核;牙齿缺损;金属铸造桩核 The comparision of the clinical effect of glass fiber post and core cast metal post and core in the re
