Poly(methylmethacrylate) Microwave Processing: A Technique Paper
Now online in the Journal of Prosthodontics, Drs. Audrey M. Selecman and Brian A. Brodine, describe a processing technique that yields a complete dental prosthesis in under two hours. The authors provide step by step guidelines for microwave processing of a wax trial denture into a poly(methylmethacrylate).
They note that the microwave processing technique, aided by fast-set, type III stone and the abandonment of the boil out and processing tanks allows for a substantial decrease in processing time.
The reduced processing time of this technique could provide many benefits. For example, the authors explain that it may decrease a laboratory technician’s exposure to free monomer, reduce travel time for patients with poor health or transportation constraints, present an option to patients with impending social events or travel plans, or provide access to care to patients in underserved areas.
The denture produced using the technique described in the article exhibited satisfactory surface quality and was bio-compatible with the underlying tissues. The patient was highly satisfied with the fit and function of the prosthesis.
The authors conclude that microwave processing of compression-molded, heat-cured poly(methylmethacrylate) provides an efficient, cost-effective and energy conscientious method for fabricating acrylic resin dental prostheses.
