  • Method for the manufacture of dental restorations
    Publication number: 20040109783
    Abstract: 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.
