To solve such a problem that a complicated process started from the formation of a mold for reproducing the oral cavity of a patient is required in the conventional production of an artificial tooth (a prosthetic article such as a crown, a denture or a dental plate) and quality is influenced by the skillfulness of a dental technician.

A compound prepared by mixing a metal, ceramics, a resin powder and a binder in a proper compounding ratio is directly shaped on the basis of data of the teeth shape and bed of a patient by carbon dioxide laser according to a lamination and accumulation method (rabbit plot type) to produce an artificial tooth. It is necessary to preliminarily obtain the data of the teeth shape and bed of a patient but the sharp labor saving of a manufacturing process, the enhancement of quality and the improvement of work environment are enabled.
