Abstract

Denture material properties can be improved by various fiber addition. The most often used denture materials are polymethyl methacrylate (PMMA) resins; nevertheless, they do not have a high flexural strength (FS). This investigation compared the mechanical characteristics of an injection-molded polyamide. Deflex, an additional injection-molded PMMA base material, SRIvocap, and a typical compression-molded PMMA (Meliodent). The flexural qualities (deflection, bending strength, and bending modulus) of 100 different denture base materials were assessed. Specimens measuring (13 x 4.5 x 4 mm3) and fulfilling Bureau of Indian Standards (BIS) specification number requirements were created. On an Instron testing apparatus with a 5 mm/min crosshead speed, a three-point bending test was performed. To compare microhardness results, the Knoop hardness test was employed. Tensile test and bending test suggested that chopped glass fibre with other natural fiber shows the maximum strength. SEM test shows the good bonding of fibre with PMMA. High amount of GF can also be harmful so optimum wt. percentage composition used in testing procedure. It is observed that, hybrid mixing materials generate an ideal combination in the resulting composite by offering improved balance and stability between the qualities of the combined fillers. Hence, it is recommended to use natural and vegetable fibres for future work
