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 pled where tensile stresses are expected to occur, while the brittle particulate filled veneer is placed where compressive stresses are expected to occur.

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

Dental restorations are fabricated using metal powder. Preferably, the metal powder is a high fusing metal and preferably, the metal powder comprises a non-oxidizing metal. The metal powder is applied to a die and is covered with a covering material such as a refractory die material preferably in the form of a flowable paste. A second covering material may be sprinkled or dusted onto the paste. The model is then dried prior to firing. After drying, the model is sintered to provide a high strength metal restoration. After sintering, the outer shell can be broken off easily with one's hand to expose the sintered coping.

Method for the manufacture of dental restorations

Process for the manufacture of dental restorations using high strength ceramic components. A wax pattern is built around a high strength ceramic component on a die. The wax pattern with the high strength ceramic component is surrounded with investment material. The wax is burned out, leaving a mold with the high strength ceramic component. The mold is filled with a ceramic material, covering the high strength ceramic component, creating a dental restoration.
