Fiberreinforced Composite Resin Pontics

Composite resins can be used in fixed partial dentures without a metal substructure (see Chapter

27). A substructure matrix of impregnated glass or polymer fiber provides structural strength. The physical properties of this system, combined with its excellent marginal adaptation and esthetics, make it a possible metal-free alternative for FPDs, although long-term clinical performance is not yet known.
