This study examined the average surface roughness (Ra, micron) of two composites and three different hybrid ionomers before and after treatment with a 12-fluted finishing bur, two finishing and polishing systems, and a hybrid-ionomer glaze for the hybrid ionomers. The 12-fluted finishing bur produced a roughened surface with all materials compared to the initial surface formed and cured against glass. Both the Enhance Finishing and Polishing System and the Sof-Lex contouring and polishing disks produced smoother surfaces for the composites, Revolution and Charisma, compared to the hybrid ionomers, Fuji II LC, Variglass, and Vitremer. However, the Fuji II LC glaze and the Vitremer glaze created smoother surfaces compared to Revolution finished with the Enhance system. Overall, the Sof-Lex disk system produced the smoothest surfaces for all materials.
本研究检测了两种复合材料和三种不同的混合性玻璃离子水门汀在使用12刃精修车针、两种精修和抛光系统以及用于混合性玻璃离子水门汀的混合性玻璃离子水门汀釉料处理前后的平均表面粗糙度（Ra，微米）。与在玻璃上成型并固化的初始表面相比，12刃精修车针使所有材料的表面变得粗糙。与混合性玻璃离子水门汀Fuji II LC、Variglass和Vitremer相比，Enhance精修和抛光系统以及Sof-Lex轮廓和抛光盘使复合材料Revolution和Charisma的表面更光滑。然而，与使用Enhance系统精修后的Revolution相比，Fuji II LC釉料和Vitremer釉料产生的表面更光滑。总体而言，Sof-Lex盘系统使所有材料的表面最光滑。
