Fabrication, characterization, and selection using FAHP-TOPSIS technique of zirconia, titanium oxide, and marble dust powder filled dental restorative composite materials

The article aimed to develop and characterize the nano-micro ceramic particle-filled polymer-based composite as dental materials. The current study also deals with the ranking of dental composites using a hybrid fuzzy analytic hierarchy process (FAHP)-fuzzy technique for order of preference by similarity to ideal solution (FTOPSIS) methodology. Dental composites were fabricated from resin matrix and ceramic particulates. Two different series were fabricated. Zirconia, titanium oxide, and marble dust powder were used as ceramic particles in the dental composite. Bis-GMA, TEGDMA, CQ, and DMAEMA were employed for the resin matrix of dental composite. The physical and mechanical properties were investigated for both dental formulations. The maximum and minimum compressive strengths were recorded in DM-6 (321 MPa) and DT-0 (190 MPa). Polymerization shrinkage was gradually decreased in both hybrid nZr-TiO2 and hybrid nZr-MDP formulations. The FTOPSIS was used to determine the rank of alternatives as DT-6 > DM-6 > DM-4 > DT-4 > DM-2 > DM-0 > DT-0 > DT-2.
