摘要：

背景：对于一些要做后牙烤瓷全冠但又不宜或不愿多磨牙齿的患者来说，做全金属边缘烤瓷全冠是一种较好的解决办法。但金属烤瓷冠有很多种类，每种材料的性能及对人体的影响也不一样，文章选择3种常用的材料进行研究，希望能给临床医生提供参考。
目的：探讨使用镍铬合金、钴¬铬合金、高金合金3种金属制作的全金属边缘烤瓷冠修复后牙的临床应用效果。
方法：制作150个后牙全金属边缘烤瓷冠，分为镍铬合金组、钴¬铬合金组、高金合金组，每组50个冠。2年后比较龈缘染色和边缘密合情况。
结果与结论：龈缘染色情况高金合金组 < 钴铬合金组 < 镍铬合金组，边缘密合情况高金合金组最好，钴¬铬合金组稍优于镍铬合金组，但差异无显著性意义。结果提示后牙全金属边缘烤瓷冠最好使用高金合金，钴¬铬合金次之，最好不要选用镍铬合金。

Abstract:

BACKGROUND: As for patients candidate for porcelain complete veneer crown of posterior teeth but are unwilling to grind teeth, full metal edge porcelain crown is a better solution. However, there are many types of porcelain to metal, the performance of each material may affect human body to different degrees. The article aims to compare three kinds of commonly used materials, and to hopefully give clinicians a reference.
OBJECTIVE: To study the clinical application effects of three kinds of full metal edge porcelain to metal based on Ni-Cr alloy, Co-Cr alloy and high gold alloy for the repair of posterior teeth. 　
METHODS: A total of 150 full metal edge porcelain to metal in posterior teeth were prepared and then divided into 3 groups: Ni-Cr alloy group, Co-Cr alloy group and high gold alloy group. There were 50 crowns in each group. Two years later, gingival color and edge compactness were observed.
RESULTS AND CONCLUSION: The gingival color changes were high gold alloy group < Co-Cr alloy group < Ni-Cr alloy group. The edge compactness was the best in high gold alloy group, then Co-Cr alloy group and last Ni-Cr alloy group, but the latter two groups had no statistical significance. The high gold alloy is suggested to apply on full metal edge porcelain to metal, then Co-Cr alloy, and Ni-Cr alloy is not suggested.
