case_images: After the wax boil-out procedure, the acrylic substructure was positioned on the master cast (Figure 5). The substructure was made hollow (as seen in Figure 5 and care was taken to maintain the space for metal encapsulator during packing of silicone) so that the silicone engages it from all around and adhesives were also applied on its surface to bond with silicone.
