摘　　要：目的探讨不同染色时间对氧化锆陶瓷渗透深度的影响。方法采用3Shape软件CAD/CAM获得27个烧结前或预烧结氧化锆试件,按染色时间分为5、10、15、20、30、60、120、180、240 s 9组,每组3个试件。将试件中1个10 mm×10 mm的面暴露,其他5个面用指甲油封闭,浸入A2专用染色液中染色,清洁、烧结、冷却后备用。比较各组的染色渗透深度、试件色彩和试件表面元素。结果随着试件染色时间延长,渗透深度逐渐加深,差异有统计学意义(P<0.05);随着试件染色时间延长,L^(*)值逐渐下降,a^(*)值、b^(*)值逐渐升高,差异有统计学意义(P<0.05);试件浸泡30~120 s的ΔE值均处于0.0~1.5 NBS范围内,提示与A2比色版颜色匹配;EDS分析显示,试件横断面仅发现O、Zr氧化锆陶瓷特有的金属元素,还有C元素,均未发现氧化物着色剂元素。结论浸泡染色时间会影响氧化锆陶瓷烧结后的表面色彩特征、染色渗透深度。Objective To investigate the influence of different dyeing time on the penetration depth of zirconia ceramics.Methods A total of 27 pre-sintered or pre-sintered zirconia specimens were obtained by 3Shape software CAD/CAM.According to the dyeing time,they were divided into 9 groups of 5,10,15,20,30,60,120,180,240 s,with 3 specimens in each group.One 10 mm×10 mm surface of the test piece was exposed,and the other five surfaces were sealed with nail polish,immersed in A2 special dyeing solution for dyeing,cleaned,sintered,and cooled for later use.The dye penetration depth,specimen color and specimen surface elements were compared.Results As the staining time of the specimen was extended,the penetration depth gradually deepened,and the difference was statistically significant(P<0.05).As the staining time of the specimen was prolonged,the L^(*)value gradually decreased,and the a^(*)and b^(*)values gradually increased,the difference was statistically significant(P<0.05).TheΔE values of the specimens immersed for 30-120 s were in the range of 0.0-1.5 NBS,indicated that they matched the color of A2 colorimetric plate.EDS analysis showed that only metal elements unique to O and Zr zirconia ceramics and C elements were found in the cross section of the specimen,and no oxide colorant elements were found.Conclusion The immersion dyeing time will affect the surface color characteristics and dye penetration depth of zirconia ceramics after sintering.
