摘要：

背景：在非贵金属烤瓷合金中，钴铬烤瓷合金在生物相容性、耐腐蚀性以及金属稳定性方面都优于镍铬烤瓷合金和含钛烤瓷合金，被广泛的应用于临床。
目的：通过与德国BEGO钴铬合金对比，评价自制钴铬烤瓷合金的金瓷结合性能。
方法：制作25 mm×3 mm×0.5 mm规格的德国BEGO钴铬合金与自制钴铬烤瓷合金两种合金的金属试条，分别熔附8 mm× 3 mm×1 mm的VITA MK 95瓷粉，采用三点弯曲的方法测试金瓷结合力，利用扫描电镜观察金属氧化界面。
结果与结论：加力后国产和德国BEGO钴铬合金样本随着力量的增加瓷层开裂同时完全脱落，表面成灰黑色氧化膜，无明显瓷残余；自制钴铬烤瓷合金与德国BEGO钴铬合金的金瓷结合力差异无显著性意义[(41.26±2.68), (41.35±2.59) MPa，   P > 0.05]。说明自制钴铬烤瓷合金的金瓷结合强度高于ISO所要求的基本值25 MPa，且与德国BEGO钴铬合金相比无差异，可满足临床要求。

Abstract:

BACKGROUND: Co-Cr alloy has better biocompatibility, anti-corrosion and stability than Ni-Cr and Ti alloy. It is more and more used extensively.
OBJECTIVE: Compared to the Germany BEGO cobalt-chromium alloy, to make initial evaluation to the combination of ceramic to metal of the new-type Co-Cr alloys.
METHODS: VITA MK95 porcelain powder of 8 mm×3 mm×1 mm was fused to the two types of alloys of 25 mm×3 mm×0.5 mm and the combination of ceramic to metal of the two types of alloys was tested using three-point flexure bond test and scanning electron microscope.
RESULTS AND CONCLUSION: For two kinds of alloys after strength loading, ceramic layer cracked and detached completely at the same time, gray-black oxide film formed on the alloy surface, and there was no significant residual porcelain (P > 0.05). The bonding of ceramic to metal of the new type Co-Cr alloys is greater than the basic value of the required ISO (25 MPa), which do not different from that of the Germany BEGO and meet the clinical requirements.
