Using the Remnants of Pomegranate Peel Particles to Strengthen the Bases of PMMA Dentures

Polymethylmethacrylate (PMMA) resin was used as a basic material in this research with pomegranate peel particles with fractional masses ((0,5,10,15 ,20%,25 ,30 %) as a cementing material with a granular size of 45µm)). Samples for mechanical tests to study mechanical properties (bending, shock, thermal conductivity) and at laboratory temperature (27°C(. The results of mechanical tests represented by (bending, shock) showed that the best value obtained for the bending modulus is (67Mpa) at a mass fracture of 10%. Moreover, the best value for the shock resistance is (58kJ/m2) at 20% mass fracture, and the thermal conductivity property decreases to the lowest value (0.71W/m.c°) due to the increased reinforcement with pomegranate peels
