制作方法对钴铬合金金瓷结合性能的影响
目的比较铸造钻铬合金与选区激光熔化（SLM）钴铬合金金瓷结合强度的差异。方法用铸造法和SLM技术制作钴铬合金试件各10个，在中间1／3区域熔附瓷粉，采用剪切力试验测试金瓷结合强度并观察断裂类型。采用SPSS13．0软件中的t检验对结果进行统计学分析。结果铸造组、SLM组剪切力分别为（33．11±4．98）、（30．94±5．98）MPa，二者间差异无统计学意义（P〉0．05）。样本的断裂类型为复合断裂。结论SLM钴铬合金修复体精密度较高，其金瓷结合强度与铸造钴铬合金相近。...

| Abstract_FL | Objective To compare the shear bond strength(SBS) of cast Co-Cr alloys and selective laser melting(SLM) Co-Cr alloys with those of dental porcelain. Methods A dental porcelain (Vita) was applied on cast and SLM Co-Cr alloy specimens(n=10). SBS test was conducted, and fracture mode analysis was determined. Student’s t-test by SPSS 13.0 soft- ware was employed to analyze the data. Results The SLM Co-Cr alloy specimens had lower SBS values than the cast Co-Cr alloy specimens (P>0.05). The metal-porcelain bond strength value of the cast group was (33.11±4.98) MPa, and that of the SLM group was (30.94±5.98) MPa. The specimens in both test groups exhibited mixed failure. Conclusion The metal-porcelain system processed by SLM exhibit a bond strength that is similar to that of the cast group. This system also display a high precision. |
