摘　　要：目的对比研究镍铬合金与金沉积对前牙烤瓷熔附金属(porcelain-fused-to-metal crown,PFM)全冠修复患者的应用效果以及对龈沟液(gingival crevicular fluid,GCF)炎症因子的影响。方法选入2020年9月-2022年2月在本院接受前牙PFM全冠修复的患者86例(86颗牙),根据修复材料不同分为镍铬合金组和金沉积组,每组43例(43颗牙)。比较两组的治疗效果、GCF炎症因子水平等指标。结果金沉积组修复体颜色、边缘密合度、边缘着色及继发龋均显著优于镍铬合金组(P<0.05),在修复体折裂瓷崩方面,两组无明显差异(P>0.05);修复6个月后,金沉积组GI、PD、GCF和GCF中TNF-α、IL-6、IL-1β和MMP-2水平水平均显著低于镍铬合金组(P<0.05);金沉积组满意度显著高于镍铬合金组(93.02%vs.74.42%,P<0.05)。结论镍铬合金与金沉积均是前牙PFM全冠修复的常用材料,而后者对患者局部牙周组织影响较小,在减轻GCF炎性因子水平、提高修复美观度及患者满意度方面优于前者。Objective To compare the effect of nickel chromium alloy and gold deposition on the restoration of porcelain fusion-to-metal crown(PFM)and gingival crevicular fluid(GCF)inflammation factors.Methods 86 patients(86 teeth)who received porcelain fused to metal crown restoration of anterior teeth in our hospital from September 2020 to February 2022 were selected.According to different restoration materials,they were divided into Ni-Cr alloy group and gold deposition group,with 43 cases(43 teeth)in each group.The therapeutic effect and the level of inflammatory factors in gingival crevicular fluid were compared between two groups.Results The restoration color,edge fit,edge coloration and secondary caries in the gold deposition group were significantly better than those in the nickel-chromium alloy group(P<0.05).After 6 months of repair,the levels of TNF-α,IL-6,IL-1βand MMP-2 in GI,PD,GCF and GCF in the gold deposition group were significantly lower than those in the nickel-chromium alloy group(P<0.05).The satisfaction degree of gold deposition group was significantly higher than that of the nickel-chromium alloy group(93.02%vs.74.42%,P<0.05).Conclusion Nickel chromium alloy and gold deposit are commonly used materials for PFM crown restoration of anterior teeth.The latter has little impact on the local periodontal tissue of patients,and is superior to the former in reducing the level of GCF inflammatory factors,improving the restoration aesthetics and patient satisfaction.
