Abstract
A method for forming removable dentures using injection molding techniques wherein a cyanoacrylate base material is applied to the sides of the denture teeth, an activator or accelerator compound being sprayed onto the deposited base material whereby the base material is rapidly cured. The denture is then placed in the lower half of a mold, or flask, and a plurality of sprues are positioned therein. The upper flask portion is then attached to the lower half and the assembled flask is then invested with plaster material. The activated gel enables the teeth to be retained in position in the lower half of the flask. The flask is then placed in hot or boiling water and then deflasked to remove the melted wax. The flask is then reassembled and polymer injected therein filling the areas previously occupied by the wax. After the polymer is cured, the prothesis is removed, polished and then returned to the dentist.
