摘　　要：目的探究计算机辅助设计/计算机辅助制作(CAD/CAM)氧化锆全瓷冠修复体对全冠修复患者牙周组织健康状况及炎症反应的影响。方法选择2020年8月至2021年12月本院收治的全冠修复患者82例,按随机数表法分为两组,各41例。对照组采用镍铬合金烤瓷冠修复,观察组采用CAD/CAM氧化锆全瓷冠修复,于修复12个月后评估。比较两组牙周组织健康状况、炎症反应。结果修复前,两组牙周组织健康状况、炎症反应比较差异无统计学意义(P>0.05);修复12个月后,观察组牙周探诊深度(PD)(2.02±0.31)mm、牙龈出血指数(SBI)(1.33±0.16)分、菌斑指数(PLI)(1.05±0.12)分均低于对照组,龈沟液量(1.57±0.23)μl少于对照组,肿瘤坏死因子-α(TNF-α)(322.61±28.56)ng/L、白细胞介素-6(IL-6)(245.76±15.24)ng/L、C反应蛋白(CRP)(52.43±6.19)mg/L均低于对照组,差异有统计学意义(P<0.05)。结论与镍铬合金烤瓷冠修复相比,CAD/CAM氧化锆全瓷冠修复能够更为有效地改善全冠修复患者牙周组织的健康状况,减轻炎症反应。Objective To explore the effect of computer aided design/computer aided manufacturing(CAD/CAM)zirconia all-ceramic crown prosthesis on the periodontal tissue health and inflammatory reaction of patients with complete crown restoration.Methods From August 2020 to December 2021,a total of 82 patients with complete crown restoration were selected and divided into two groups according to random number table,41 patients in each group.The control group was repaired with nickel-chromium alloy porcelain fused to metal crown,and the observation group was repaired with CAD/CAM zirconia all-ceramic crown,which was evaluated after 12 months of repair.The health status and inflammatory reaction of periodontal tissue in the two groups were compared.Results Before restoration,there was no significant difference between the two groups in periodontal health and inflammatory reaction(P>0.05);After 12 months of restoration,the periodontal probing depth(PD)(2.02±0.31)mm,gingival bleeding index(SBI)(1.33±0.16)points and plaque index(PLI)(1.05±0.12)points in the observation group were lower than those in the control group,and the gingival crevicular fluid volume(1.57±0.23)μl Less than the control group,tumor necrosis factor-α(TNF-α)(322.61±28.56)ng/L,interleukin-6(IL-6)(245.76±15.24)ng/L,C-reactive protein(CRP)(52.43±6.19)mg/L were significantly lower than those in the control group(P<0.05).Conclusion Compared with Ni-Cr alloy porcelain fused to metal crown,CAD/CAM zirconia all-ceramic crown can more effectively improve the periodontal health and reduce inflammation in patients with full crown restoration.
