In this study, the optimal formulations of dental restorative composite materials were determined using a hybrid FAHP-FTOPSIS approach. Various performance defining attributes were considered, and the weight criteria were evaluated using FAHP. The results showed that DHZ4 was the best choice. This research is significant for evaluating different types of dental restorative composite materials.
In the present investigation, the optimal formulations of dental restorative composite materials were designed using hybrid FAHP (Fuzzy Analytic Hierarchy Process)-FTOPSIS (Fuzzy Technique for Order of Preference by Similarity to Ideal Solution) methodology of statistical techniques. The dental composite was composed of an organic matrix and different types and ratios of inorganic filler. The various performance defining attributes (PDAs) such as compressive strength, flexural strength, depth of cure, and polymerization shrinkage were taken into account to evaluate the optimal formulation of dental restorative composite materials. The weight criteria of PDAs was evaluated by the FAHP; PDA-1 (0.084, 0.083, 0.083), PDA-2 (0.084, 0.095, 0.102), PDA-3 (0.079, 0.097, 0.110), PDA-4 (0.084, 0.108, 0.124), PDA-5 (0.084, 0.091, 0.093), PDA-6 (0.062, 0.083, 0.113), PDA-7 (0.070, 0.081, 0.098), PDA-8 (0.058, 0.071, 0.090), PDA-9 (0.073, 0.074, 0.092), PDA-10 (0.070, 0.076, 0.089), and PDA-11 (0.157, 0.135, 0.098), respectively. The FTOPSIS is used to determine the rank of alternatives as DHZ4 > DHZ8 > DHZ0 > DHZ6 > DHZ2. The Hybrid FAHP-FTOPSIS technique was significant in ranking analysis of different dental restorative composite materials under conflicting PDAs.
