AIM The aim was to evaluate the biomechanical behavior of the supporting bony structures of replanted teeth and the periodontal ligament (PDL) of adjacent teeth when orthodontic wires with different mechanical properties are applied, with three-dimensional finite element analysis. MATERIALS AND METHODS Based on tomographic and microtomographic data, a three-dimensional model of the anterior m...

In this study, various mechanical behaviors of a shape memory alloy, depending on different thermal and electrical conditions to be used in areas such as biomedical, aerospace aeronautics. Temperature changes length change rates under current values alloy named “nickel titanium”, or “nitinol” (NiTi) has been observed. It seen that 0.3 mm diameter wire can generate force 25 N while the material ...

OBJECTIVE Using the Hörmann technique of hyoid suspension in sleep apnea surgery, a steel wire is placed through the thyroid cartilage and slung around the hyoid bone. However, we experienced thyroid cartilage fracture by steel wire traction. A modification is presented to avoid thyroid cartilage fracture. STUDY DESIGN Case series with chart review. SETTING University hospital. SUBJECTS A...

Description The OSTEOMED Logic Mandibular Distraction System is an intraoral bone distractor. It features various curved and straight bars activated with an activation wire (threaded wire) that has screw holes that are fixed to bone via 1.6mm or 2.0mm bone screws. The distractor is available in right and left versions. The activation wire is activated by a hex driver and is capable of distracti...

in this study, gtaw process and cored wires were used to coat al/al3ti wear resistant composite on a commercial pure al substrate. wire drawing process was utilized to produce the cored wires from aluminum strips and a mixture of titanium and aluminum powders. the microstructures and the present phases were investigated by metallographic, sem equipped with eds and xrd analysis. moreover, the ha...

Hybrid reconfigurable logic circuits were fabricated by integrating memristor-based crossbars onto a foundry-built CMOS (complementary metal-oxide-semiconductor) platform using nanoimprint lithography, as well as materials and processes that were compatible with the CMOS. Titanium dioxide thin-film memristors served as the configuration bits and switches in a data routing network and were conne...

The object of this study is structural formation during the surfacing steel (iron) on titanium with plasma-sprayed coatings to obtain a butt connection titanium-steel bimetallic plates. task be solved was devise technology for applying barrier layer between and defect-free joint edges sheets carbon steel, clad titanium, under conditions arc or plasma titanium. application carried out by sprayin...

Method Porcine cardiac xenografts were treated by decellularization, immunologic modification with alpha-galactosidase, space filler, GA fixation in organic solvent, and detoxification. The nitinol (Nikel-Titanium, shape memory alloy) frame is comprised of a braided wire that reverts to its original shape and locks the valve into position as deployed. We manufactured the stented valve with the ...
