摘　　要：目的:评价镍铬合金、钛合金和钴铬合金烤瓷冠对牙周组织的影响。方法:选择需要制作镍铬合金、钛合金和钴铬合金烤瓷冠的患者各50例,分别于修复前、戴牙3、6、12个月后提取其龈沟液进行检测。结果:1镍铬烤瓷冠组戴牙3、6、12个月龈沟液值高于牙体预备前,有显著性差异;2钴铬烤瓷冠组、钛合金烤瓷冠组戴牙3、6、12个月龈沟液值与牙体预备前无显著性差异;3镍铬烤瓷冠组龈沟液值均高于其他两组,有显著性差异。Objective： to investigate the Ni-Cr casted porcelain fused crown, titanium alloy and Co-Cr alloy casted porcelain fused crown on periodontal tissue. Method： need to make Ni-Cr casted porcelain crown, titanium alloy and Co-Cr alloy porcelain crowns each 50 cases of patients, respectively, before the fix, 3,6 and 12 months to extract the GCF detection. Date were statistically. Result：the Ni-Cr group after restoration GCF quantitily was changed significantly, the 3 months, 6 months, 12 months is higher than before the tooth preparation; the group of Co-Cr and titanium alloy casted porcelain fused crown teeth 3 months, 6 months, has no significant difference in the 12 months before the tooth preparation. Ni-Cr each time period were higher than the other two groups, there is a significant difference.
