Abstract

Common metallurgically produced materials are utilized in the production of dental products. During production, however, not all of the material can be utilized. When the material is subsequently processed by casting, a lot of energy is required for melting. The invention relates to a method for producing dental castings or a material for dental castings. According to the invention, fine particles of the material are to be partially fused and the fused particles are to be compacted. This results in a sintered semifinished product. During subsequent processing using casting techniques, this sintered semifinished product can be easily cast into dental castings in a pot of a casting device. The sintered semifinished product offers a good homogeneity during mechanical subsequent processing. The sintered semifinished products produced according to the inventive method are suited for all dental products which are produced by means of casting, especially for implant constituents, crowns, bridges and model casts.
