This study investigated the effectiveness of intraoral and technical polishing kits. Zirconia specimens were sintered, ground, and polished with 14 different two-step or three-step polishing kits. Surface roughness (Ra, Rz) after each treatment step was determined, and scanning electron micrographs were made. Except for one system, all polishing kits were effective in reducing the surface roughness of ground zirconia. Differences in surface roughness were high after the first polishing step but were reduced to Ra/Rz values similar to or lower than those of the sintered reference after the final polishing step. Achieving smooth surfaces depended on a sequential application of all polishing steps.
本研究调查了口腔内及技术用抛光套件的有效性。对氧化锆样本进行烧结、研磨，并使用14种不同的两步或三步抛光套件进行抛光。测定每个处理步骤后的表面粗糙度（Ra、Rz），并制作扫描电子显微镜图像。除了一个系统外，所有抛光套件均能有效降低研磨后氧化锆的表面粗糙度。在第一个抛光步骤后，表面粗糙度差异较大，但在最终抛光步骤后，Ra/Rz值降低至与烧结参考样本相似或更低的水平。获得光滑表面取决于依次应用所有抛光步骤。
