    Abstract: Dental devices having folded material. A dental appliance may include a specialized region configured to impart one or more specialized forces to one or more particular areas of a patient's dentition. The specialized region may include a reinforcement structure including a rigid three- dimensional structure, where the rigid three-dimensional structure includes repeating geometric shapes defined by folds in a sheet of one or more polymeric materials. The folds may be folded along a pattern of lines according to the repeating geometric shapes. The rigid three-dimensional structure may have a greater thickness than the unfolded sheet so as to impart a greater rigidity to the specialized region compared to the unfolded sheet, thereby reinforcing the specialized region for imparting the one or more specialized forces to the one or more particular areas of the patient's dentition.

    Abstract: A method for manufacturing a sheet laminate to be affixed to an adherent surface of an object, the method comprising preparing a sheet member having a front surface to become a design surface and a rear surface on which an adhesive part has been formed, bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold, and heating a part of a bent sheet member. The sheet laminate has a flat part spreading out in a flat plate shape, a side surface on which the edge part bent by the bending step is configured, and a connecting surface protruding and curving toward the front surface side between the flat part and the side surface, and in the heating step, the connecting surface is partially heated after the side surface is molded in the bending step.

    Abstract: The present invention discloses a method for preparing stable 3D polymer objects with surface micro-nanostructures. The method includes the following steps: Step (1): Synthesizing a thermoset 2D polymer object with surface microstructures. The polymer network contains reversible exchangeable bonds. Step (2): deforming synthesized polymer to an arbitrary desired shape above the reshaping temperature with an external force applied. The permanent reshaping temperature falls in the range of 50-130° C. and external stress is held for 5 min-24 hours Step (3): after cooling, a permanent 3D polymer object with surface microstructure is obtained. Step (2-3) can be repeated for many cycles and the 2D polymer object can be arbitrarily and cumulatively deformed to get a complex 3D structures. The polymer networks contain reversible exchangeable bonds and bond exchange catalysts in the present invention. The method disclosed in present invention is simple and efficient for preparing complex 3D polymer objects with surface micro-nanostructures.
