Description
Summary:Composite resin is quickly becoming the most extensively utilized material in the field of cosmetic and restorative dentistry. It eliminates the problem of poisonous nature caused by the amalgam's mercury content. This research article is based on the outcome of adding micro‐alumina and zirconia particulates filled dental composites on the physical properties, mechanical properties, and wear analysis. Three dental composites named AZDC2, AZDC4, and AZDC6, were prepared. Alumina microparticles were constant (6 wt%) while zirconia microparticles were varying (2, 4, and 6 wt%). Two‐body wear was performed on pin‐on‐disc friction & wear test rig under dry sliding for all three dental composites under different normal load (20, 40, and 60 N) and sliding speed (10, 15, and 20 mm/s). The experiments were designed as per L9 Taguchi orthogonal array. The least volumetric wear was found in AZDC6 dental composite under a sliding velocity of 15 mm/s and a normal load of 20 N. From the ANOVA analysis, normal load and filler content were the significant factors affecting the volumetric wear with a significance level 5%, respectively. Dental composite AZDC6 exhibited maximum compressive strength (451.49 MPa). Micro hybrid particulates‐filled dental composites improve physical and mechanical characterization.
