Performance of Different Polishing Techniques for Direct CAD/CAM Ceramic Restorations

Abstract

Clinical Relevance VITA Mark II and IPS Empress CAD specimens polished with Sof-Lex discs exhibit smoother surfaces than glazed specimens. The investigated ceramic polishing systems are universally applicable and show increased durability, but they do not result in smoother surfaces than Sof-Lex treatment. Furthermore, certain steps of some polishing methods do not contribute to improved smoothness and could be omitted.
