Abstract: Dental composite restorations reinforced with one or more fiber structures are disclosed. The fiber structures can have a wide array of shapes and sizes, including rods with circular cross sections, rods with “U” shaped cross sections, rods with “I” shaped cross sections, and fiber mesh structures. The reinforced dental composite restorations are created by incrementally layering and curing composite materials onto the fiber structures. The resulting restorations have significantly improved flexural strength as compared to conventionally prepared composite restoration materials.
