Summary
Titanium dioxide nanoparticle (TiO₂ nanoparticle) coatings enhance removable acrylic resin prosthetic bases. These coatings improve wear resistance, antimicrobial activity, glossiness, and color stability, extending denture lifespan.
Area of Science:
- Materials Science
- Biomaterials Engineering
- Nanotechnology
Background:
- Removable acrylic resin prosthetic bases are susceptible to surface degradation and microbial contamination.
- Improving the surface properties of these materials is crucial for enhancing patient outcomes and device longevity.
Approach:
- A systematic review was conducted to evaluate the impact of titanium dioxide nanoparticles (TiO₂ nanoparticles) on acrylic resin surfaces.
- Searches of PubMed, Scopus, and Science Direct (2009-2023) were performed, supplemented by manual searches.
- The modified Consolidated Standards of Reporting Trials (CONSORT) checklist was used for study quality assessment.
Key Points:
- TiO₂ nanoparticle coating demonstrated significant improvements in polymethylmethacrylate (PMMA) surfaces compared to uncoated controls.
- Coating enhanced antimicrobial activity, wear resistance, surface glossiness, and color stability.
- These improvements contribute to increased durability and a longer functional lifespan for dentures.
Conclusions:
- TiO₂ nanoparticle coating positively alters the surface properties of PMMA, enhancing mechanical, physical, and biological characteristics.
- Further research is needed to determine optimal TiO₂ nanoparticle coating thickness and concentrations for clinical use.
