三种复合树脂表面粗糙度的实验研究

An empirical study on surface roughness of the latest three dental filling materials

目的:比较3种牙体充填材料的表面用在粗糙度。方法:抛光过程中以粗糙度测试仪分别测试3M Filtek Supreme XT、Venus、ceram XMono试件表面经0.5、1.0、1.5、2.0、2.5、3.0、3.5、4.0min抛光头抛光后的粗糙度值并进行统计学分析。结果:3种充填材料的表面粗糙度程度不等,Venus>ceram XMono>3M Filtek Supreme XT。结论:充填材料的表面粗糙度以3M Filtek Supreme XT为最佳。经统计分析,与其他两组充填材料相比有显著性差异。

AIM： To compare the surface roughness of three dental filling materials. MTHODS： Three dental filling materials（ 3M Filtek Supreme XT ,Venus and ceramX ） were selected. The surface of the specimens were sequentially polished with polishing bur at 0.5 min ,1.0 min ,1.5 min ,2.0 min ,2.5 min ,3.0 min ,3, 5 min ,4.0 min, then the degree of surface roughness of each sample was evaluated. RESULTS ：The degree of surface roughness varied among the dental filling materials with seguence of Venus 〉 ceramX Mono 〉 3M Filtek Supreme XT. CONCLUSION： The 3M Filtek Supreme XT has the best slick and less roughness than the others.
