Abstract
Objective To investigate the effects of polishing and reglazing on surface roughness of nanostructured ceramic. Methods Forty discal samples of nanostructured ceramic IMAGINE REFLEX were fabricated and randomly divided into 2 groups,then the surfaces of 20 specimens of group A were sequentially polished with SiC water proof abrasive papers from 240# to 1500# grits,respectively,and finally polished with diamond polishing paste. The other 20 disks were reglazed (group B). The surface roughness of each specimen following reglazing and polishing treatments was analyzed qualitatively and quantitatively using scanning electron microscopy(SEM). Results No significant difference in roughness values was found between reglazing and polishing treatments of IMAGINE REFLEX ceramic(P0.05).SEM results showed similar smooth surface for showed two groups,and polishing treatment showed some fine cracks. Conclusion Polishing could attain the same smooth surface,compared with reglazing treatment of IMAGINE REFLEX ceramic.
