PURPOSE The use of titanium for implants has shown the biological acceptance of the metal. Recently, methods of using titanium for restorations, crowns, and bridges have been introduced using both cast and spark erosion systems for fabrication. A potential also exists for using titanium for bonded (Maryland) bridges. MATERIALS AND METHODS In this study, the potential for bonding titanium was ...

In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with 1) no polishing process (A sample), 2)electropolishing process (B sample) and 3) electropolishing process in ethanolicelectrolyte (C sample). To study the ...

Nanoparticles of titanium increase cell growth by improvement of photosynthetic and nitrogen metabolism and therefore, caused an increasing in weight of the plant. This re-search was conducted to evaluate seed yield and biochemical traits of bread wheat affected by different levels of titanium dioxide Nanoparticles in Ahvaz region, Khuzestan province, located at southwestern Iran by factorial e...

Pigment grade titanium dioxide is composed of sub-micron sized particles, including a nanofraction, and is widely utilized in food, cosmetic, pharmaceutical, and biomedical industries. Oral exposure to pigment grade titanium dioxide results in at least some material entering the circulation in humans, although subsequent interactions with blood immune cells are unknown. Pigment grade titanium d...

A technique to create an individually modified implant prosthetic abutment is described. An overcasting is waxed onto a machined titanium abutment, cast in titanium, and joined to it with laser welding. With the proposed technique, a custom-made titanium implant prosthetic abutment is created with adequate volume and contour of metal to support a screw-retained, metal-ceramic implant-supported ...

BACKGROUND Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. AIMS To investigate in vitro CoCr and commercially pure...

Ni-Hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. In this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the Ni-hard 4 cast iron with the nominal composition of Si= 1.5%, Mn=0.5%, C=3%, P=0.05%, S= 0.05%, Mo= 0....

Abstract Titanium cranioplasty is one of the well-established and widely used techniques in restoring skull defects for optimal protection to skull internal structures and reestablishing skull conformity. Nowadays, most centres utilise computer-assisted reconstruction for manufacture of titanium plates. In this paper we presented a method for making titanium cranioplasty plates using the 3D inn...

UNLABELLED Some surface treatments performed on titanium can alter the composition of salivary pellicle formed on this abiotic surface. Such treatments modify the titanium's surface properties and can promote higher adsorption of proteins, which allow better integration of titanium to the biotic system. PURPOSE This study aimed to evaluate the interactions between salivary proteins and titani...

PURPOSE To evaluate the magnetic characteristics, artifact formation, and implant safety of titanium aneurysm clips for use in MR imaging. METHODS Aneurysm clips made of titanium alloy TiAl6V4 were tested in a magnetometer to determine their magnetic susceptibility and in a 1.5-T MR imager using both a geometric phantom and an animal model. A commercially available alpha-Phynox clip served as...
