| خلاصه مقاله | Many studies were carried out to improve the properties of the denture base materials by adding suitable fillers into PMMA denture base. In recent years, many attempts have been made to use nanoparticles in dental acrylic resin to improve its thermal conductivity, impact strength, and antibacterial properties. The effects of the fillers on the properties the composite materials depend on their morphology, size distribution, hydrophobicity and dispersion quality. PMMA-grafted nanoclay as filler for dental adhesives improved the dispersion stability of the particles and increased the shear bond strength of the adhesive. Adding nanoclay particles to PMMA improved its thermal conductivity, while it had a negative effect on the flexural strength. Incorporation of the modified nanoclay fillers increased the flexural strength of PMMA. However incorporation of unmodified particles did not significantly affect the flexural strength and tensile toughness. Therefore by organo-modification of nanoclays, its compatibility and incorporation with resin based materials will increase. |
