镍铬合金

Nickel chromium alloy was cheaper than nickel, and its sputtering aggradation velocity was more than that of nickel, so the immediacy costs of sputtering nickel chromium alloy electrode was less than that of sputtering nickel electrode.

镍铬合金价格低于镍金属，溅射沉积速率也比镍金属要快，所以溅射镍铬电极的直接成本低于溅射镍电极。

The amount of Ni and Cr released from specimens coated with gold was much fewer than those from unplated specimens (P .05), which meant the stability of Ni-Cr alloy on the surface was improved. The biocompatibilities of gold-coated Ni-Cr alloy were better than the uncoated alloy, though there was no difference in biological ranking.

说明其耐电化学腐蚀能力明显提高；镀金后镍铬合金试件的镍离子、铬离子析出量降低，表面稳定性有了显著性提高；无氰镀金法镀金的镍铬合金生物相容性良好，从数据上比较优于未镀金镍铬合金，但生物学评级上无显著性差异。

Roast a porcelain hat according to inside hat material different, mainly is divided into Nie chrome the metal alloy roast a porcelain hat, titanium cobalt the metal alloy roast porcelain hat, gold leaf metal alloy to roast porcelain hat and gold deposition to roast a porcelain hat.

烤瓷冠根据内冠材料不同，主要分为镍铬合金烤瓷冠、钛钴合金烤瓷冠、金铂合金烤瓷冠以及金沉积烤瓷冠。

GCF was collected from labial and lingual of mesial site and distal site before the tooth preparation by filter paper. At the point of 6 month after cementation, GCF was collected at the same sites. The level of was collected at the same sites. The level of TNF-α was detected by enzyme-linked-immunoadsorbent assay method, and analyzed the variation between the pre-restoration and post-restoration.

选择临床病例24例，采用镍铬合金烤瓷冠和金铂合金烤瓷冠修复，分别在修复前、修复后6个月进行临床检查和取GCF，进行GCF量和TNF-α水平的测定。

Results: Compared with pre-restoration, all indexes had significant difference between the Ni-Cr alloy group and the Au-Pt alloy group after 6 month.

结果 6个月时镍铬合金组与金铂合金组在指标上均有明显差异。
