自制钴铬烤瓷合金机械性能的实验研究

Experimental Study on the Combining Strength about Homemade Co-Cr Ceramic Alloys as Basal Metals and Porcelain Systems

目的:测试自制钴铬烤瓷合金的机械性能,为其临床应用提供参考。方法:实验分2组,A组自制钴铬烤瓷合金,B组BEGO钴铬烤瓷合金,金属规格均为12mm×4.7mm×5mm,瓷层规格均为4.4mm×3.8mm×2mm,采用剪切强度测试法观察金瓷结合力。结果:A组金瓷结合破坏力为(33.31±1.30)Mpa,B组金瓷结合破坏力为(34.60±1.12)MPa,统计分析二者差异无显著性(P>0.05)。结论:自制钴铬烤瓷合金具有较强的金瓷结合力,值得在临床中广泛应用。

Objective：To compare the combining strength between different basal metals which were homemade Co-Cr Ceramic alloys and Imported materials and porcelain systems and to provide a reference for clinical applications.Methods：The combining strength of interfaces between different metals and porcelain systems were tested through shear bond strength assay.Results：There was no significant difference on shear bond strength between A（homemade Co-Cr Ceramic alloys） and B（Imported materials）（P0.05）.Conclusion：Homemade Co-Cr Ceramic alloys have good shear bond strength and can be used in clinic.
