“…Such metals meet the existing requirements for use in oral defect restoration [102,103]. Furthermore, TiO 2 can also be utilized as a reinforcing agent in dental and biocomposite fabrication because of its antimicrobial properties and biocompatible features [88,104,105]. Khaled et al [32] enhanced the mechanical properties of commercial acrylic cement by introducing novel nanostructured titania tubes (n-TiO 2 tubes) into the cement matrix.…”

Poly(methyl methacrylate) (PMMA) is an extensively used material in dentistry because of its aesthetics, processability, and reparability. However, PMMA is still far from being ideal in fulfilling the mechanical requirements of prosthesis. PMMA-based denture base polymers exhibit low fracture resistance and radiopacity behavior. Efforts to improve the mechanical and radiopacity properties of denture base materials through inclusion of silica-based fillers are ongoing. Although silane-treated siliceous fillers are commonly used, they are not sufficiently strong. They also exhibit cracks, which either cut through the glass fillers or propagate around the filler particles. This defect occurs when the dental composites are placed in aqueous oral environment because of the hydrolytic degradation of silica-based fillers and silane-coupling agents. The clinical problem of using silanes in adhesion promotion is bond degradation over time in oral environment. In addition, silanes do not bond effectively to nonsilica-based dental restorative materials. This review presents titanium-derived fillers as alternatives to siliceous fillers. Titanate-coupling agents are found to be effective couplers in treating Ti-based fillers because of their chemical compatibility and relatively high stability in aqueous environment.

“…Sintering was done at 1300 ºC that enables forming of clusters that enabled high filler loading without counteracted viscosity of the nanoparticles. In this study the 1 wt% of TiO 2 nanoparticles loading was used according to previous studies which revealed that it positively improves the mechanical properties of the resin composite including microhardness, flexural strength and flexural modulus (15,16) .…”

“…For a nanotubular oxide layer formed on the Ti6Al4V ELI screw, the division into an α-phase rich in aluminum and β-phase rich in vanadium was observed. Despite the presence of toxic vanadium in the β-phase of Ti6Al4V ELI, the anodizing process caused its oxidation reducing toxic effect from a metal substrate [2,35,36]. The oxide layer prepared on Ti6Al4V ELI transpedicular screws are hereinafter designated as: "Ti6Al4V" for bare transpedicular screw, "Compact Ti6Al4V" for transpedicular screw anodized in 1 M H 3 PO 4 resulting in compact oxide formation and "Nanotubular Ti6Al4V" for transpedicular screw anodized in ethylene glycol (99%) with 0.6 wt.% NH 4 F addition resulting in nanotubular layer formation.…”

Nano-engineered implants are a promising orthopedic implant modification enhancing bioactivity and integration. Despite the lack of destruction of an oxide layer confirmed in ex vivo and in vivo implantation, the testing of a microrupture of an anodic layer initiating immune-inflammatory reaction is still underexplored. The aim of this work was to form the compact and nanotubular oxide layer on the Ti6Al4V ELI transpedicular screws and electrochemical detection of layer microrupture after implantation ex vivo by the Magerl technique using scanning electron microscopy and highly sensitive electrochemical methods. For the first time, the obtained results showed the ability to form the homogenous nanotubular layer on an Ti6Al4V ELI screw, both in α and β-phases, with favorable morphology, i.e., 35 ÷ 50 ± 5 nm diameter, 1500 ± 100 nm height. In contrast to previous studies, microrupture and degradation of both form layers were observed using ultrasensitive electrochemical methods. Mechanical stability and corrosion protection of nanotubular layer were significantly better when compared to compact oxide layer and bare Ti6Al4V ELI.
