When restoring large cavities in posterior endodontically treated teeth, usually are treated with indirect laboratory-fabricated onlays or crowns. If the patient for any reason, after being informed of the various treatment options and costs, desires to have the restoration done within one appointment, a direct reinforced restoration might be the best choice. The purpose of this article suggests the use of two different materials; polyethylene fibers and resin composite to treat endodontic treated tooth offering a high strength restoration within one appointment. The polyethylene fibers, besides offering the proper strength to the mastication forces, as well reduce the risk of fractures and microfiltration. This procedure demonstrated some advantages over the usual conventional more expensive alternatives that may take more than one visit.

High-strength cable-steel bridge is the “lifeline” of steel structure bridges, which requires high comprehensive mechanical properties, and cold-drawing is the most important process to produce high-strength cable-steel bridge. Therefore, through the ABAQUS platform, a bridge wire drawing model was established, and the simulation analysis on the process of stress strain law and strain path trends for high-strength bridge steel wire from Φ 12.65 mm by seven cold-drawing to Φ 6.90 mm was conducted. The simulation results show that the wire drawing the heart of the main axial deformation, surface and sub-surface of the main axial and radial deformation occurred, with the increase in the number of drawing the road, the overall deformation of the wire was also more obvious non-uniformity. In the single-pass drawing process, the change in the potential relationship of each layer of material was small, and multiple inflection points appeared in the strain path diagram; the change in the seven-pass potential relationship was more drastic, which can basically be regarded as a simple superposition of multiple single-pass pulls.
