Fabrication and characterization of micro alumina zirconia particulate filled dental restorative composite materials

Abstract

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.

Tribological behavior of zinc oxide‐hydroxyapatite particulates filled dental restorative composite materials

“…It is an investigative method employed for the elemental analysis or chemical characterization of the composite material specimen. [ 34 ] Figure 9 designates different crests, like Calcium, Phosphorus, Silicon, Zinc, Carbon, Oxygen, and Nitrogen essentials. All these fundamentals were implemented in zinc oxide and nano‐hydroxyapatite reinforced dental samples.…”

Viability and Adhesion of Periodontal Ligament Fibroblasts on a Hydroxyapatite Scaffold Combined with Collagen, Polylactic Acid–Polyglycolic Acid Copolymer and Platelet-Rich Fibrin: A Preclinical Pilot Study

“…Biomaterials have been widely used in periodontal regeneration as well as in the restoration of compromised dentitions with dental implants [ 33 , 34 ]. Likewise, biomaterials have been used in deciduous teeth restoration affected by cavities, where in the long term, an HAp interphase between the dental tissue and the biomaterial should be observed, characteristic of these biomaterials [ 35 ].…”
