摘要：

目的：分析非贵金属烤瓷冠引起牙龈变色、炎症的原因，对镀金方法作出改进,为临床应用镀金烤瓷冠提供参考。方法：选择2005年6月?006年12月来本科就诊的患者240例，介绍镍铬合金、镀金镍铬合金、以及高金合金烤瓷冠的区别，按患者自愿选择烤瓷冠（PFM）类型的要求分为3组。镀金组: 镀金烤瓷冠80例；镍铬合金组:镍铬合金烤瓷冠80例；高金合金组：高金合金烤瓷冠80例。对3组烤瓷冠的牙龈变色及牙龈健康情况进行观察、比较。结果：初戴时,镍铬合金组有3例出现牙龈变色，而镀金组和高金合金组均无1例出现牙龈变色，但组间比较差异无显著性(P>0.05)。3组烤瓷冠均无牙龈炎症出现。1年后,镍铬合金组共出现12例牙龈变色,与镀金组及高金合金组(无1例) 比较差异有显著性 (P<0.01)。镍铬合金组出现13例、镀金组出现3例牙龈红肿现象，经秩和检验，镍铬合金组与镀金组、高金合金组比较差异有显著性(均P<0.01)，镀金组与高金合金组比较差异无显著性(P>0.05)。结论：从龈缘的美学效果和适中的价格来看，高度抛光镀金烤瓷冠是临床修复比较理想的选择。

Abstract:

Abstract:Objective To analyze the reason of dyeing and inflammation of gum caused by the non- precious metal porcelain crown,make improvements on the methods of gold-plated and provide a reference for the clinical application of gold-plated porcelain crown.Methods 240 patients who needed porcelain-fused-to-metal crown(PFM) repair from June,2005 to December,2006 were selected.The differences of nickel-chromium alloy,gilded nickel-chromium alloy,and aurum alloy (PFM) were introduced to patientsThe patients were divided into three groups according to their voluntary choice of PFM.Gilded Ni-Cr alloy PFM group: 80 cases of gilded Ni-Cr alloy PFM; Ni-Cr alloy PFM group: 80 cases of Ni-Cr alloy PFM; Aurum alloy PFM group: 80 cases of aurum alloy PFM.Then the gum discoloration and gingival health in these groups were observed and compared.Results After the first wearing of PFM,three cases of gum discoloration occurred in Ni-Cr alloy group while no cases occurred in other two groups;but there was no significant difference between Ni-Cr alloy PFM and gilded Ni-Cr alloy PFM and aurum alloy PFM groups(P>0.05)；and there was no gingival inflammation in the three groups.One year later,there were twelve cases of gum discoloration in Ni-Cr alloy PFM group,while no cases occurred in gilded Ni-Cr alloy PFM and aurum alloy PFM groups,there was significant difference between them(P<0.01).　Thirteen cases of gingival redness and swelling symptoms appeared in Ni-Cr alloy group and three cases occurred in gilded Ni-Cr alloy PFM group;by means of rank sum test,the difference between them was significant (P<0.01);there was no cases occurred in in aurum alloy PFM group;the difference between Ni-Cr alloy group and aurum alloy PFM group was significant,too(P<0.01),but the difference between gilded Ni-Cr alloy PFM group and aurum alloy PFM group was not significant(P>0.05).Conclusion In view of the esthetic effects of gingival margin and moderate price,highly gilded Ni-Cr alloy PFM is an ideal choice in clinical rehabilitation.
