Abstract: A ceramic powder having a uniform particle diameter of 50 .mu.m or smaller is used as a dental ceramic powder to produce a high-precision and compact artificial tooth. The ceramic powder fired assures a non-porous and compact structure of the artificial tooth. In a manufacturing method for the artificial tooth, the cream of ceramic powder is poured into a core, the core with the ceramic cream loaded is frozen to shape, thawed, dried and then fired in a furnace. To assure even more compact structure, the cream is compacted and hardened prior to freezing. Pressure is efficiently applied in the compaction and hardening process.
