摘　　要：背景:全冠修复体远期疗效的维持很大程度上取决于牙周组织的健康状况。目的:探讨CAD/CAM氧化锆全瓷冠修复体对牙周组织健康状况的影响。方法:随机选择需行全冠修复的55例患者64颗基牙作为研究对象,实验组为CAD/CAM氧化锆全瓷冠修复的29例患者32颗基牙,对照组为进行镍铬合金烤瓷冠修复的26例患者32颗基牙。检测两组修复前和修复后12个月的龈沟液含量、肿瘤坏死因子α和白细胞介素6水平,以及牙龈出血指数、牙周探诊深度、菌斑指数及附着丧失。结果与结论:实验组修复前后各指标比较差异均无显著性意义(P>0.05)。对照组修复12个月后的龈沟液含量、肿瘤坏死因子α、白细胞介素6、牙龈出血指数、牙周探诊深度及菌斑指数均高于修复前(P>0.05)。修复12个月后,实验组龈沟液含量、肿瘤坏死因子α、白细胞介素6、牙龈出血指数、牙周探诊深度及菌斑指数均低于对照组(P<0.05)。表明CAD/CAM氧化锆全瓷冠修复后对牙周组织健康基本无不良影响。BACKGROUND:To maintain the long-term effect of ful crown largely depends on the health of periodontal tissues. OBJECTIVE:To explore the effect of CAD/CAM zirconia al-ceramic crown restoration on the state of periodontal health. METHODS:Sixty-four abutments of 55 patients were randomly divided into two groups:the experimental group included 32 abutments of 29 patients which would be restored by CAD/CAM zirconia al-ceramic crowns;the control ed group included 32 abutments of 26 patients which would be restored by Ni-Cr al oy porcelain-fused-to-metal restorations. The volume of gingival crevicular fluid and the levels of interleukin-6 and tumor necrosis factor-αin the two groups were examined at the pre-restoration and post-restoration stages. Meanwhile, periodontal clinical indicators, including sulcus bleeding index, probing depth, plaque index and attachment loss were recorded. RESULTS AND CONCLUSION:No difference in various indexes was found in the experimental group before and after restoration (P>0.05). At 12 months after restoration, in the control group, the volume of gingival crevicular fluid, the levels of interleukin-6 and tumor necrosis factor-α, sulcus bleeding index, probing depth, and plaque index were al increased (P>0.05);meanwhile, these indexes in the experimental group were significantly lower than those in the control group (P<0.05). Experimental findings suggest that the CAD/CAM zirconia&nbsp;al-ceramic crown restoration is more favorable to the health of periodontal tissues.
