How do different types of prophy pastes affect the surface gloss of various ceramic materials? The aim of an Italian-based in vitro study was to answer this question. Proxyt Fine achieved excellent results in this study.
In the study, which was presented at the AIC 19th International Congress in Bologna, test specimens made of ceramic reinforced with leucite (IPS Empress CAD; Ivoclar Vivadent), lithium disilicate (IPS e.max CAD; Ivoclar Vivadent) and zirconium oxide (Zenostar; Wieland**) were examined. The specimens were finished and then glazed. Subsequently, they were polished for two minutes at 2000 rpms using three different fine prophy pastes. The following products were used: Cleanic (Kerr/Hawe), Nupro (Dentsply) and Proxyt Fine (Ivoclar Vivadent). The control group did not receive any further treatment.
Shining results The results showed that Proxyt Fine is very low in abrasiveness. Polishing with this innovative prophy paste maintained the surface gloss of the IPS Empress CAD and IPS e.max CAD test specimens. The zirconium oxide ceramic (Zenostar) samples exhibited better gloss values after polishing with Proxyt Fine than without polishing.

Clinically proven Proxyt Fine is suitable for treating the surfaces of valuable restoration: The cutting-edge prophy paste imparts restorations with a smooth, scratch-free surface and natural-looking shine. Polishing with Proxyt Fine, therefore, provides a professional solution for maintaining the high-quality of restorations and implants in the long term.
