“…Its main disadvantages are the instability of color, poor resistance to wear and tear, volume shrinkage after the polymerization, oral mucosa irritation, and aging, and staining or discoloration relatively easily occurs [3]. Nowadays, most products for dental restoration have been produced from acrylic resins based on heat-cured PMMA, due to its optical properties, biocompatibility, and aesthetics [52,53]. However, it has a long-standing drawback that is lack of strength particularly under fatigue failure inside the mouth and also shows low abrasion resistance and microbial adhesion onto PMMA to long-term PMMA wearers.…”

In recent years, lots of researches have been launched on nanomaterials for biomedical applications. It has been shown that the performances of many biomaterials used in prosthodontics have been significantly enhanced after their scales were reduced by nanotechnology, from micron-size into nanosize. On the other hand, many nanocomposites composed of nanomaterials and traditional metals, ceramics, resin, or other matrix materials have been widely used in prosthodontics because their properties, such as modulus elasticity, surface hardness, polymerization shrinkage, and filler loading, were significantly increased after the addition of the nanomaterials. In this paper, the latest research progress on the applications of nanometals, nanoceramic materials, nanoresin materials, and other nanomaterials in prosthodontics was reviewed, which not only gives a detailed description of the new related investigations, but also hopefully provides important elicitation for future researches in this field.

“…To date, up to 95% dental prostheses are composed of Poly(Methyl MethAcrylate) (PMMA), due to its advantages, including its optical properties, biocompatibility, and aesthetics [1,2]. However, important issues are still to be addressed in order to improve acrylic polymers properties for artificial dentures.…”

Nowadays, most products for dental restoration are produced from acrylic resins based on heat-cured Poly(Methyl MethAcrylate) (PMMA). The addition of metal nanoparticles to organic materials is known to increase the surface hydrophobicity and to reduce adherence to biomolecules. This paper describes the use of nanostructured materials, TiO2and Fe2O3, for simultaneously coloring and/or improving the antimicrobial properties of PMMA resins. Nanoparticles of metal oxides were included during suspension polymerization to produce hybrid metal oxides-alginate-containing PMMA. Metal oxide nanoparticles were characterized by dynamic light scattering, and X-ray diffraction. Physicochemical characterization of synthesized resins was assessed by a combination of spectroscopy, scanning electron microscopy, viscometry, porosity, and mechanical tests. Adherence ofCandida albicanscells and cellular compatibility assays were performed to explore biocompatibility and microbial adhesion of standard and novel materials. Our results show that introduction of biocompatible metal nanoparticles is a suitable means for the improvement of conventional acrylic dental resins.

“…Its discovery has been recognized as an historical milestone in the development of nanomaterials. Now, MMT has been applied in many polymers, such as polyacrylate ester, 1,2 poly (methyl methacrylate), 3,4 polyurethane, 5,6 epoxy, 7,8 polyethylene, 9,10 and polypropylene, 11,12 etc. Ding et al [13][14][15][16] also reported the application in PVAc, but they mainly focused on the preparation of PVAc-MMT initiated by g-ray radiation intercalation polymerization and the co-blending of PVAc-MMT with high density polyethylene.…”

Polyvinyl acetate (PVAc) is considered to be a type of environmental friendly adhesive, and montmorillonite (MMT) is a cheap and accessible natural nanomineral. MMT was first organically activated by dioctadecyl dimethyl ammonium bromide (DOAB). The intercalated nanocomposite of MMT-DOAB was added during the synthesis of PVAc in conventional laboratory conditions. The PVAc-MMT-DOAB was mainly studied by X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, static tension, and the rheology was also investigated by the power-law function equation and the Cross—Williamson model viscous equation. The exfoliated nanocomposite of PVAc-MMT-DOAB could be obtained. Linear macromolecular chains of PVAc were formed in the layers of MMT-DOAB. MMT-DOAB was exfoliated into nanoparticles of layers or sheets, randomly dispersed in the matrix of PVAc. The particle diameter of MMT-DOAB ranged from 25 to 75 nm, they randomly dispersed with PVAc particles. In addition, the smaller MMT-DOAB particles were adsorbed around the bigger PVAc particles; they formed the ‘strawberry’ structure. PVAc and PVAc-MMT-DOAB were pseudo-plastic non-Newtonian fluids and they all possessed the normal stress effect (or Weissenberg effect), that was the pole-climbing phenomenon. The reasonable addition of MMT-DOAB in polymerization was found to be not more than 2.0 wt.% of VAc.
