Abstract: Methods for performing operations on a die or dental model including the filling in or "basing up" of voids, deep areas and undercuts; the indexing and investment soldering of dental crowns from a die model; and aid in the fabrication of porcelain jacket crowns and the like; the invention particularly contemplates the use of a cyanoacrylate compound to effect said methods. According to the present methods, a high viscosity cyanoacrylate base material, typically the methyl or ethyl ester of the cyanoacrylate is deposited on the die model in the areas which are to be based up, blocked out or the like, an activator or accelerator compound such as an aromatic amine or the like being then sprayed, preferably in an atomized mist form, onto the deposited base material.
