To develop a high-strength dental silicone-based curable material having excellent operation efficiency without increasing paste viscosity even when silica is increased.

The dental silicone-based curable material is obtained by including hydrophobized silica having 100-2,000 nm primary particle diameter, preferably hydrophobized dry silica in a silicone-based curable material comprising an organopolysiloxane (A) having 2 organic groups having an unsaturated bond at the terminal in the molecule, an organohydrogenpolysiloxane (B) having 3 SiH groups in the molecule and a hydrosilylation reaction catalyst substance (C).
