Treatment of clavicle fracture is principally outpatient. Operative treatment is accompanied by the need for more x-rays and possible complications. Fractures with absolute indications for operative treatment occur only sporadically and these indications are relatively clear, but children often undergo surgery because of relative indications (shortening, fragment displacement, multifragmentary ...

UNLABELLED The relationship between orthodontic force and friction produced from an archwire and brackets affects the sliding of the wire in the leveling stage. OBJECTIVE The purpose of this study was to evaluate the relationship between force and friction in a small esthetic nickel-titanium (Ni-Ti) wire. MATERIAL AND METHODS Five esthetic wires (three coated and two plated) and two small, ...

OBJECTIVE This research aimed at comparing the qualitative chemical compositions and the surface morphology of fracture regions of eight types of Nickel/Titanium (NiTi) conventional wires, superelastic and heat-activated (GAC, TP, Ormco, Masel, Morelli and Unitek), to the wires with addition of copper (CuNiTi 27ºC and 35ºC, Ormco) after traction test. METHODS The analyses were performed in a ...

The objective of the present work was to investigate the effect of the wire electrical discharge machining process parameters on material removal rate of titanium alloy using Taguchi approach. A brass wire of 250μm was applied as a tool electrode to cut the specimen. L36 mixed orthogonal array (2 ×3) has been selected for experimentation under different variables like dielectric conductivity, p...

For the first time, a geometry has been developed to allow for an axial imaging system for wire-array Z-pinch experiments that produce high-resolution x-ray images. The new geometry required a significant redesign of the electrode hardware. Calibrated areal density measurements of the Z-pinch plasma including wire cores, coronal plasma, streaming plasma, and the precursor were obtained. The sys...
