PURPOSE: A crown manufacturing method and a crown using the same are provided to obtain natural color by forming a block of zirconia with gradations of various colors. CONSTITUTION: A crown manufacturing method and a crown using the same include the following steps: a block forming step(S1) where forming a block of full zirconia by laminating zirconia raw materials; a milling step(S2) where milling the formed block using CAD and CAM; a sintering step(S3) where sintering a processed crown at 1500-1560°C; and a polishing step(S4) where polishing the crown sintered from the sintering step. The block forming step contains a step of forming a block with gradations. [Reference numerals] (S1) Block forming step; (S2) Milling step; (S3) Sintering step; (S4) Polishing step
