Prosthetic Reconstruction of Auricular Defects with an Adhesive-Retained Epithesis: A Clinical Report

models were poured by using type 3 dental stone (Giludur, BK Giulini). Thereafter, wax patterns of epitheses (Figure 2) were prepared by using dental wax (Cavex Set Up Wax, Cavex) based on cast models and photographs of healthy ears. After the trial of wax patterns on patients in terms of marginal fit and anatomical localization, cast models were molded (Figure 3). The molds were then placed in 100 °C boiling water for 20 min to remove all the wax material (Figure 4). An isolant liquid (C.M.S., Dentsply) was applied to all pieces before condensation of silicone material. A heat temperature maxillofacial silicone (Cosmesil Series M511, Principality Medical) was used to fabricate epitheses. The catalyst and putty parts were mixed according to the manufacturer’s instructions. Color pigments and fibers (Cosmesil, Principality Medical) were primarily used in intrinsic coloration of silicone material. At first, small pieces of silicone material in different skin shades were condensed to external margins in a step-by-step manner to reflect all surface colors (Figure 5). Subsequently, a principal skin shade was prepared and applied to all parts of molds. Coloration process was performed by using photographs of healthy ears as well as a skin shade to match computer and daylight visualization. After condensing silicone material, molds were placed in 100 °C boiling water for 1 hour. After the polymerization process and finishing procedures, extrinsic coloring agents (Cosmesil, Principality Medical) were applied to external surfaces (Figure 6). Final adjustments were made on patients. Margins of epitheses were sealed by using a tissue adhesive (Pro Bond, Principality Medical) and delivered to patients (Figure 7). Mechanical support of tissue undercuts also promoted the retention of epitheses.
