1. A method for dissipating shear forces in a mouth guard, comprising:

  • providing a mouth guard with a U-shaped cross-section formed by an inner upstanding wall with an inner surface and an outer surface and an outer upstanding wall with an inner surface and an outer surface, said inner upstanding wall and said outer upstanding wall being connected by a U-shaped occlusal line portion;

    providing at least one cusp on an upper edge portion of said outer upstanding wall and forming at least one lobe on said upper edge portion of said outer upstanding wall;

    providing a first plurality of perforations extending entirely through said inner upstanding wall, said first plurality of perforations having a first row and a second row, wherein perforations in said first and second rows are laterally offset;

    providing a second plurality of perforations extending entirely through said outer upstanding wall, said second plurality of perforations having a first row and a second row, wherein perforations in said first and second rows are laterally offset,wherein said first and second rows of said first plurality of perforations are spaced from said first and second rows of said second plurality of perforations,wherein individual perforations of said first and second plurality of perforations extend spaced from one another continuously from a rear portion on a first side of said mouth guard, across a line of symmetry, to a rear portion on a second side of said mouth guard,wherein said first and second plurality of perforations are arranged symmetrically about the line of symmetry,wherein said mouth guard is constructed of randomly distributed, randomly oriented interwoven strands of polycaprolactone molecules of random shapes and sizes to increase abrasion resistance of said mouth guard,wherein said U-shaped occlusal line portion is solid with no perforations, so that said first and second rows of perforations in said first and second plurality of perforations are the only perforations in said mouth guard;

    subjecting said occlusal line portion to shearing forces by grinding the teeth;

    transferring through said interwoven strands of polymer said shearing forces during the grinding from said occlusal line portion to said first and second pluralities of perforations in a lateral direction to dissipate the shearing forces, as well as upwardly from said occlusal line portion to said at least one cusp for dissipation therein.
