Background and objectives: Radiolucency of poly methyl methacrylate denture base resin is of great concern, and many approaches have been used to make acrylic resin dentures more radiopaque.The purpose of this study was to prepare a modified heat cure ploy methyl methacrylate denture base resin by incorporation of different weight percentages (2%, 3%, 4%, 5%, and 6%) of CaCO3 nanofiller particles, to increase its radiopacity.
Materials and methods: CaCO3 nanofiller particles (coated with a special coupling agent) were dispersed and sonicated in the acrylic monomer (liquid) in different percentages, then mixed with acrylic powder. For each test 60 specimens were prepared, the specimens were divided into 6 groups (10 for each) coded I to VI. Group I was the control group (unmodified specimens), the remaining five groups were reinforced with CaCO3 nanoparticles to achieve loading of 2%, 3%, 4%, 5%, and 6% by weight. Some physical properties were evaluated.
Results: There was a slight change of color of the acrylic, in groups II, III and IV, but there was an obvious color change of group V and VI. Also, there was a highly significant increase in the radiopacity in groups IV, V and VI.
Conclusion: Addition of 4% CaCO3 nanoparticles to the heat cure acrylic resin increases the radiopacity of the denture base significantly, without adverse effects on the color.
