case_images: A heat cure permanent record base (DPI Heat Cure, Denture Base Material; Dental Products of India) was fabricated on the gypsum master cast [Figure 3a]. The Bombay Burmah Trading Corporation Ltd., Mumbai, India). The final wash impression of the defect was made with polyvinyl siloxane monophase impression material (Aquasil Ultra Monophase Regular Set, Dentsply, USA) [Figure 3b]. To overcome occlusal discrepancies, an additional row of teeth was added with a ramp over the palatal region on the right side to provide occlusion with the lower teeth [Figure 3c].

case_images: Type III dental stone (Kalstone, Kalabhai Pvt., Ltd., Mumbai, India). The reservoir lid was fabricated with a 2-mm flexible thermoplastic sheet (BIOPLAST; Scheu-Dental GmbH, Iserlohn, Germany) [Figure 4a]. The reservoir volume was assessed to be 2 ml by injecting a known quantity of liquid with a calibrated syringe [Figure 4b]. The reservoir lid was snapped to close the reservoir [Figure 4c].

case_images: With obturator in the place, the facial defect was recorded with a complete facial moulage using irreversible hydrocolloid impression material which was reinforced with fast-setting dental plaster [Figure 5a]. The moulage was boxed and poured with dental stone (Kalstone, Kalabhai Pvt., Ltd., Mumbai, India) [Figure 5b].

case_images: Two cobalt-samarium magnets (Jobmasters, Randallstown, MD, USA) with 2-mm thickness and 10-mm diameter were embedded in the acrylic substructure and their counter magnets were embedded on the buccal surface of the obturator [Figure 6a and b]. A wax pattern was sculpted on the working model using the patient's previous photographs as a reference [Figure 6c]. Adaptation of the wax pattern on the patient's face was assessed in lateral, frontal, and axial views, particularly at the margins, and necessary adjustments were accordingly made [Figure 6d].
