Nano -Technology in Prosthodontics

Nanotechnology, the manipulation of matter at the nanoscale (1-100 nm), has significantly influenced modern dentistry, particularly in prosthodontics. The incorporation of nanoparticles into dental materials has enhanced their physical, mechanical, and biological properties, leading to improved clinical outcomes and longevity of prostheses.Nanoparticles such as silver (Ag), titanium dioxide (TiO¿), zinc oxide (ZnO), silica (SiO¿), and zirconia (ZrO¿) are commonly used in prosthodontic materials. These nanoparticles exhibit unique properties including increased surface area, high reactivity, and antimicrobial activity. When incorporated into denture base resins, luting cements, impression materials, and ceramics, they improve strength, wear resistance, esthetics, and dimensional stability.One of the major advantages of nanoparticles is their antimicrobial effect, particularly seen with silver and zinc oxide nanoparticles.
