摘要： A manufacturing method and dental component are provided in which first and second cast parts are used with a casting material, such as a gel slurry, to form the dental component. The first cast part can be positioned in a space of the second cast part and a gel slurry can be applied intermediate the first and second cast parts. The gel slurry can then be solidified to form a solidified gel slurry. The first cast part can then be removed together with the solidified gel slurry from the second cast part. The solidified gel slurry can then be machined to form an exterior shape corresponding to a desired exterior shape of the dental component. Finally, the solidified gel slurry can be sintered.
