ABSTRACT:
An artificial tooth is provided that includes a cutting mass brought into hardened condition by light polymerization, a tooth bone mass brought into hardened condition by light polymerization, and a base mass. Those masses bordering one another are intensively interconnected with one another. The process for producing an artificial tooth includes subjecting the cutting mass disposed in a mold to light polymerization, subsequently disposing the tooth bone mass on the first mass while the cutting mass is still disposed in the mold, and subjecting the tooth bone mass to light polymerization with light passed through the mold and the cutting mass disposed in the mold.
