Nanoparticle-reinforced resin-based dental composites

Reinforcement of flowable dental composites with titanium dioxide nanotubes

“…Also, copolymerization of the vinyl double bond in MA results in formation of nTiO 2 -PMMA composite [39]. Nanosized TiO 2 reinforcing fillers were introduced to dental composites by Xia et al [40] in form of nanoparticles. Allyltriethoxysilane, (ATES) was used for functionalization of these nanoparticles.…”

“…Another study tried to improve the mechanical properties of dental composites by reinforcing them with TiO 2 nanoparticles (< 20 nm) functionalized with allytriethoxysilane (ATES) [40]. The mechanical properties of these composites were compared to those of composites reinforced with non-functionalized (NF) TiO 2 nanoparticles and to composites with no TiO 2 nanoparticles.…”

Silver doped titanium dioxide nanoparticles as antimicrobial additives to dental polymers

“…Although studies have shown that the incorporation of antibacterial agents, such as chlorhexidine can dramatically reduce bond strength [26], other have shown that incorporation of TiO2 nanoparticles also improves the microhardness and flexural strength of dental composites [27]. It may be that Ag-TiO2 particles not only provide adhesive resins with inherent antimicrobial properties, but also might simultaneously improve mechanical properties.…”

Evaluation of Bioactive Nano Composite Fillers Effect on Wear Resistance of Composite and Enamel Surfaces

“…Nanoparticles used in biomedical dental restorative materials to improve mechanical properties and increase wear resistance of used material (Xia et al, 2008;Tian et al, 2008).…”
