ABSTRACT:
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. The composition gets hardened by low alkalinity and is very low in tissue irritation.
