Change in color of a maxillofacial prosthetic silicone elastomer following investment in molds of different materials

摘要

Purpose:In the authors’ experience, the color of silicone elastomer following polymerization in molds made of gypsum products is slightly different from the color that was matched in the presence of the patient, before the silicone is packed. It is hypothesized that the investing materials and separating media have an effect on the color during the polymerization process of the silicone.
