Dental bridges comprising fiber reinforced frameworks with fiber or particulate reinforced veneers

摘要

A dental restoration comprising a fiber reinforced composite framework and one or more of a randomly dispersed, fiber-filled veneer, a soft particulate filled composite veneer having a strain to failure greater than that of FRC framework and/or a brittle particulate filled composite veneer having a strain to failure value less than that of the FRC framework. The fiber filled veneer is advantageously placed beneath the framework, the soft veneer is advantageously placed where tensile stresses are expected to occur, while the brittle particulate filled veneer is placed where compressive stresses are expected to occur.
