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.
目的
探讨CAD/CAM氧化锆全瓷冠、钴铬合金及银钯合金烤瓷熔附金属冠修复对牙周组织的临床疗效及影响。
方法
将46例患者的49颗带冠牙齿随机分为CAD/CAM氧化锆全瓷冠组、钴铬合金烤瓷熔附金属冠组和银钯合金烤瓷熔附金属冠组。分别在修复前及修复后12个月分析龈沟液（GCF）、肿瘤坏死因子-α（TNF-α）和白细胞介素-6（IL-6）的含量，并评估临床疗效。
结果
比较3组的临床疗效，CAD/CAM氧化锆全瓷冠组的颜色匹配度和牙龈状况等指标明显优于其他2组（P<0.05）。CAD/CAM氧化锆全瓷冠组的GCF、TNF-α和IL-6含量也明显优于其他2组（P<0.01）。
结论
CAD/CAM氧化锆全瓷冠修复的临床疗效优于钴铬合金和银钯合金烤瓷熔附金属冠修复，且对牙周组织无明显损害。
