Wear resistance is of paramount importance for the long-term success dental materials, especially when they are used extensive indirect restorations in full-mouth rehabilitations. The present vitro study aimed to evaluate two-body wear a new and recently introduced CAD/CAM resin composite disc (Ena Cad, Micerium S.pA.), compare it other two well-known already marketed composites (Brilliant Crios, Coltene/Whaledent AG; Grandio disc, Voco Gmbh) conventional type 3 gold alloy (Aurocast 8, Nobil-Metal). Ten cylindrical specimens (diameter 8 mm, height 6 mm) were manufactured with each material subjected test dual-axis chewing simulator, performing 120,000 cycles opposing antagonists (2-mm-diameter round tip) made out same corresponding materials. total vertical (mm) volumetric loss (mm3) sample/antagonist pair calculated. Representative scanning electron microscope images also taken. Data statistically analyzed using one-way analysis variance tests. No significant differences recorded among properties restorative materials under investigation. Ena Cad showed comparable Brilliant Crios disc.
