This invention relates to a base material composition for dental treatment comprising 100 parts by weight of alumina cement powder, 1-50 parts by weight of calcium type powder hardening retarder, and 1-20 parts by weight of hardening retarder for restraining dispersion of calcium ion. This composition has appropriate hardening time and consistency, and is higher in strength and lower in solubility.
