Comparing Between Two Different Fillers To Improve The Radiopacity And Aesthetics Of Denture Base Materials

Abstract

Poly (methyl methacrylate) (PMMA) is the material of choice for denture base construction. In spite of its many good qualities, the application of PMMA as an ideal dental base material is still restricted by a few limitations. These limitations can be overcome by adding additives such as fibers and fillers into the polymer matrix to form polymer composites. The aim of this study was to shine a light on the ways and methods of improve some properties of the PMMA denture base materials since it is not considered an ideal material for constructing denture bases. One of the ways of improving the denture base is by adding fillers to the acrylic resin. It was concluded that, the addition of these fillers at suitable amount to PMMA significantly improved the radiopacity of PMMA composite. Also, each filler showed some different effects on the composite especially the aesthetics.
