The Effect of CaSiO3 Nano-Particles Reinforced Denture Polymethyl Methacrylate

Abstract: The preparation of CaSiO 3-PMMA nanocomposite denture matrix was reported. We investigated the optimal amount of CaSiO 3 nano-particles modified by silane coupling agent (Z-6030) on strengthen flexural strength and surface hardness (Knoop hardness) of the nano-CaSiO 3 /PMMA composite materials. The results indicated that the 1.5% CaSiO 3 nano-particles could enable the nanocomposite to have the maximum flexural strength (90.50±4.86) MPa(increasing nearly 40% contrast to the blank group), while 2.0% CaSiO 3 nan… Show more

“…Most denture breakages occur inside the mouth during function, primarily because of flexural failure. 9 The denture base resin is subjected to various stresses during function; these include compressive, tensile, and shear stresses. Some of the factors responsible for denture fracture include stress intensification, increased ridge resorption leading to an unsupported denture base, deep incisal notching at the labial frena, sharp changes at the contours of the denture base, deep scratches, and induced processing stresses.…”
