Stabilization of an interim obturator prosthesis using a denture duplicator

Concomitant radiotherapy and chemotherapy given within weeks after major surgical procedures may require that an interim obturator prosthesis be worn for extended periods of time. Interim reline materials used in fabricating the interim obturator prosthesis may become rough and difficult to clean. With a Lang denture duplicator it is possible to easily convert an interim obturator prosthesis to an all acrylic resin prosthesis. A technique is described for this procedure.
