牙龈卟啉单胞菌和变形链球在不同方法制作的钴铬合金表面粘附能力的研究

Study on the Adhesion Ability of PorPhyromonas gingivalis and Deformed Hammer SPheres on Cobalt-Chromium Alloy Surface Made by Different Methods

本文对比评价了牙龈卟啉单胞菌和变形链球菌在激光烧结与铸造两种制作工艺下的钴铬合金表面粘附能力。两种制造方式制作AB两组钴铬合金试件,经打磨后在相同的粗糙度范围内,不同试件表面两种细菌的粘附量无统计学意义。结果表明激光烧结钴铬合金(SLM)与传统铸造钴铬合金试件表面同一种细菌的粘附能力无明显差异。

To evaluate the adhesion ability of PorPhyrinomonas gingivalis and StrePtococcus mutans on the surfaces of cobalt chromium alloy made by two manufacturing Processes(laser sintering and casting Process).The two grouP sPecimens grind to the same roughness range,on the test surface of A、B grouPs of Co-Cr alloy sPecimens.The adhesion of the two bacteria on the surface of the two grouPs have no statistically significant under the same roughness.The results show that there is no significant difference in the adhesion of CO-Cr alloy surface Produced by laser sintering and casting Process.
