Attorney, Agent or Firm: Cantor Colburn LLP

A hybrid fiber-reinforced structural component for dental restorations, wherein the hybrid reinforcing fibers comprise a core having a composite sheath bonded thereto. Preferably, the core comprises a material having a high modulus, such as tungsten, tantalum, niobium, boron or carbon. The composite sheath comprises fibers disposed within a polymeric matrix material, preferably the fibers glass or polyethylene fibers. The hybrid fiber-reinforced composite is particularly useful as a structural component for bridges or for reinforcement of a tooth restoration after endodontic treatment.

DETAILED DESCRIPTION The above-described drawbacks and deficiencies of the prior art are alleviated by the aesthetic, hybrid reinforcing fibers in accordance with the present invention, wherein the hybrid reinforcing fibers comprise a high modulus core bonded to a sheath comprising aesthetically pleasing fibers embedded within a polymeric matrix.
Advantageously, the effective hybrid fiber-reinforced composites of the present invention fall within a range of desirable moduli of elasticity for dental materials, and can be designed and engineered to provide a continuous selection of stiffness and strength over a wide range by adjusting the characteristics of the core material, size, shape and placement of the fibers.
