摘要： 目的探讨CAD/CAM氧化锆、银钯合金和钴铬合金烤瓷全冠的修复效果及对牙周影响。方法随机选择全冠修复患者46例49颗受试牙,采用3种材料进行修复（CAD/CAM氧化锆、银钯合金、钴铬合金）。修复前、后进行GCF含量、TNF-α、IL-6检测,并对修复效果进行评价。采用SPSS 18.0软件包对数据进行统计学分析。结果对照各组修复后效果,修复体颜色匹配和牙龈状况指标CAD/CAM氧化锆全瓷冠组均显著优于其他2组（P<0.05）。各组修复后GCF含量、TNF-α和IL-6检测结果,CAD/CAM氧化锆全瓷冠组均显著优于其他2组（P<0.01）。结论CAD/CAM氧化锆全瓷冠修复体修复效果好,且对患者牙周组织的破坏较小,优于银钯和钴铬合金烤瓷全冠修复体。

Abstract: PURPOSE: To investigate the clinical efficacy and effects of CAD/CAM zirconia all-ceramic crown, cobalt-chromium alloy and silver-palladium alloy porcelain-fused-to-metal crown restorations on periodontal tissues. METHODS: Forty-nine teeth with crowns in 46 patients were randomly assigned into CAD/CAM zirconia all-ceramic crown group, cobalt-chromium alloy porcelain-fused-to-metal crown group and silver-palladium alloy porcelain-fused-to-metal crown group. The amounts of GCF, TNF-α and IL-6 were analyzed before and 12 months after restorations, and the clinical efficacy was evaluated. RESULTS: Comparing the clinical efficacy within 3 groups, indicators such as color match and the status of gums in CAD/CAM zirconia all-ceramic crown group were significantly better than other 2 groups (P<0.05). The amounts of GCF, TNF-α and IL-6 in CAD/CAM zirconia all-ceramic crown group were also significantly better than other 2 groups (P<0.01). CONCLUSIONS: CAD/CAM zirconia all-ceramic crown restoration had better clinical efficacy than cobalt-chromium alloy and silver-palladium alloy porcelain-fused-to-metal crown restorations with no apparently damage to periodontal tissues.
