The present invention relates generally to methods for making dental appliances and prostheses, particularly dentures. A polymerizable dental composition is used in the method. The polymerizable dental composition comprises a polymerizable acrylic compound； a polymerization initiation system, capable of being activated by light or heat, for polymerizing the composition； and a solvent capable of at least partially solubilizing wax material. Preferably, a mixture of heptane and methyl acetate solvents is used. The compositions are able to remove wax residue effectively and improve the bonding strength of a denture baseplate to subsequently applied materials.
