How to make microwavable denture flasks.

Abstract

One can make a microwavable denture flask that will accommodate obturators and other large intraoral prostheses. A method for making a dental stone flask pattern and a latex mold makes it possible to produce fiberglass flasks strong enough for compression molding. These flasks are economical to produce and are made from the fiberglass liquid resin that is used in automobile body repairs. The fiberglass liquid resin is strengthened by the addition of dental stone and chopped fiberglass strands. The resultant flasks allow successful microwave polymerization of acrylic resin for denture bases while still being able to follow conventional flasking and packing techniques.
