摘要目的分析前牙美容修复中二氧化锆全瓷冠对牙龈健康的影响。方法49例患者共73颗前牙采用二氧化锆全瓷冠修复，设为二氧化锆组；对照组选择25例患者共32颗前牙采用铸造全瓷冠修复。分别在修复后1d和3、6、12个月参照美国加利福尼亚州牙科协会制定的标准，观察牙龈健康状况。结果二氧化锆组在修复完成第1天及第3、6个月时，牙龈健康分级I、Ⅱ级均分别为72、1颗；修复后12个月，I、Ⅱ级分别为70、3颗。对照组在修复完成第1天及第3、6、12个月时，牙龈健康分级I、Ⅱ级均分别为72、1颗。2种全瓷冠的临床效果差异无统计学意义（P〉0．05）。结论二氧化锆全瓷冠在前牙美学修复中对牙龈健康影响很小，与铸造全瓷冠较接近。 Objective To compare the effect of anterior teeth clinical restoration with zirconia all-ceramic crowns and cast all-ceramic crowns. Methods All 49 patients with 73 crowns were enrolled in zirconia group. Those anterior teeth were restored with zirconia all-ceramic crowns. The control group were selected with 32 crowns from 25 patients with cast all-ceramic crowns. One day, 3 months, 6 months, 1 year after restoration were the time points. Marginal integrity was observed according to the standards specified by the California Dental Association. Results All 73 zirconia ceramic crowns repairs were completed on day 1 and 3 months, 6 months after restoration in zirconia group. 72 anterior teeth got grade I , 1 anterior tooth got grade Ⅱ ; 1 year after the repair, 70 anterior teeth got grade I and 3 anterior teeth got grade Ⅱ. All 32 casting all-ceramic crowns restorations were completed in one day, 3 months, 6 months, 1 year after the restoration. 31 anterior teeth got grade I , 1 anterior teeth got grade Ⅱ. The clinical effects of the two types of all-ceramic crown showed no statistical difference. Conclusion Zirconia all ceramic crown has the similar gingival effect as the cast all-ceramic crowns and both of those kinds of restorations are ideal for anterior teeth repair.
