A highly bioactive bone-bonding Ti metal was obtained when Ti metal was simply heat-treated after a common acid treatment. This bone-bonding property was ascribed to the formation of apatite on the Ti metal in a body environment. The formation of apatite on the Ti metal was induced neither by its surface roughness nor by the rutile phase precipitated on its surface, but by its positively charge...

UNLABELLED The purpose of this study was to evaluate and compare the effect of grit blasting, chemical treatment, and application of alloy primer combinations on the shear bond strength (SBS) of a self-cure resin cement to titanium surface. MATERIALS AND METHODS Fifty cast commercially pure titanium discs (9 mm × 2 mm) were divided into five groups (n = 10), which received the following surfa...

BACKGROUND AND METHODS Various methods have been used to modify titanium implant surfaces with the aim of achieving better osseointegration. In this study, we fabricated a clustered nanorod structure on an acid-etched, microstructured titanium plate surface using hydrogen peroxide. We also evaluated biofunctionalization of the hybrid micro/nanorod topography on rat bone marrow mesenchymal stem ...

We have proposed a combination of density functional theory calculations and interatomic potential-based simulations to study the structural, electronic, and mechanical properties of pure-silica zeolite Linde Type A (LTA), as well as two titanium-doped compositions. The energetics of the titanium distribution within the zeolite framework suggest that the inclusion of a second titanium atom with...

Due to its alkalinity, red mud produced by the Bayer process may affect both the environment and human health. For this reason, its further utilization instead of disposal is of great importance. Numerous methods have already been studied for hydrometallurgical treatment of red mud, especially for the recovery of various metallic components such as iron, aluminum, titanium or rare earth element...

PURPOSE Hydrofluoric acid treatment of moderately rough commercially pure titanium produced by titanium oxide (TiO2) grit blasting (OsseoSpeed) results in a surface with nanofeatures. The aim of this project was to better understand the effect of surface nanotopography on adherent osteoblastic differentiation. MATERIALS AND METHODS Human mesenchymal stem cells were grown on TiO2 grit-blasted ...

nano-sized titanium dioxide tio2 powder was successfully prepared from its precursor titanium (iv) chloride by a simple and new wet chemical method. ticl4 were used as precursor in hydrogen peroxide, h2o2 and ethanol. this solution was then peptized using nitric acid and heated under reflux at 80°c. their physico-chemical properties were then characterized by transmission electron microscopy (t...

Today surface modifications of titanium implants have become a development strategy of dental implants. The present study investigated the morphology (SEM), surface elemental analysis (EDX), surface roughness (AFM) and crystalline structure (XRD) of TiO2 film prepared via anodic oxidation of grade II commercially pure titanium specimens in different electrolytic solutions and times. Incubation ...

The implant used in spinal fusion procedures is an essential component to achieving successful arthrodesis. At the cellular level, the implant impacts healing and fusion through a series of steps: first, mesenchymal stem cells (MSCs) need to adhere and proliferate to cover the implant; second, the MSCs must differentiate into osteoblasts; third, the osteoid matrix produced by the osteoblasts ne...
