Wear evaluation of the human enamel opposing different Y-TZP dental ceramics and other porcelains.
Quote: "Dental professionals should be aware of the wear effect of dental restorations on the opposing teeth or restorations. The amount of enamel wear was highest in the feldspathic porcelains whereas zirconia ceramics caused less wear on the opposing teeth." Interesting Abstract for you to further evaluate for yourself...cheers!
