Color stability of laboratory glass-fiber-reinforced plastics for esthetic orthodontic wires
OBJECTIVE In our previous study, glass-fiber-reinforced plastics (GFRPs) made from polycarbonate and glass fibers were prepared for esthetic orthodontic wires using pultrusion. These laboratory GFRP wires are more transparent than the commercially available nickel-titanium wire; however, an investigation of the color stability of GFRP during orthodontic treatment is needed. Accordingly, in the ...
متن کاملFiber- Reinforced Composite for Orthodontic Anchorage Technique
Introduction: In orthodontic treatment, adequate anchorage is necessary to move the intended teeth. In some cases, just anterior teeth are malaligned, while posterior occlusion is acceptable. Therefore, the posterior teeth could be integrated by fiber-reinforced composite (FRC) to provide a rigid anchorage. This method proved advantageous since brackets are bonded just to anter...
متن کاملColor stability and fluorescence of different orthodontic esthetic archwires.
OBJECTIVE To evaluate the color stability of six esthetic archwires at different time periods and their fluorescence. MATERIALS AND METHODS Samples were evaluated after 7, 14, and 21 days of immersion in staining solution. Color measurements were performed by means of a spectrophotometer according to the Commission Internationale de I'Eclairage L*a*b* system, and color changes (ΔE*) and Natio...
متن کاملEfficacy of Esthetic Retainers: Clinical Comparison between Multistranded Wires and Direct-Bond Glass Fiber-Reinforced Composite Splints
THE PURPOSE OF THIS LONGITUDINAL PROSPECTIVE RANDOMIZED STUDY WAS TO EVALUATE THE RELIABILITY OF TWO DIFFERENT TYPES OF ORTHODONTIC RETAINERS IN CLINICAL USE: a multistrand stainless steel wire and a polyethylene ribbon-reinforced resin composite. Moreover the level of satisfaction of the patient about the esthetic result was also analyzed by means of a Visual Analogue Scale (VAS). 34 patients ...
