Methods Four three-dimensional finite element models were constructed by the data of spiral CT:1Mandibular second premolar restored directly by full crown;2Fill the perforating cavity with resin material and full crown restoration;3Cast nickel chromium alloy post core plus full crown restoration;4Fiber post and resin core plus...

方法采用螺旋式CT扫描获取数据，建立下颌第二前磨牙4种情况下的三维有限元模型：1直接全冠修复；2用树脂材料充填开髓洞形后全冠修复；3铸造镍铬合金桩核与全冠修复；4纤维桩树脂核与全冠修复。

Methods: The color of all veneered samples that were put on noble metal,NiCr alloy,AgHg alloy and resin background was measured with chromatism instrument.

采用色差计测量各组饰瓷后试样在贵金属、镍铬合金、银汞合金和树脂背景上的色度值并计算组间色差值。

Objective To compare the adaptation of porcelain fused-to-metal restorations made from Ni-Cr alloy, precious alloy and galvanized forming copings after cementation and to provide a theory guidance for their ap-plication.

目的 对镍铬合金烤瓷冠、贵金属合金烤瓷冠和金沉积烤瓷冠的边缘适合性进行研究，为临床应用提供一定的理论依据和指导。

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。

Material: Metal die-cast, basic material zinc alloy, surface chrome plated mat

锌合金压铸，表面铬合金，用螺丝把皮绳和金属固定在一起。
