case_images: While making an impression, the external auditory canal was blocked with a cotton plug and the impression was made by irreversible hydrocolloid and with the gauge in between, and backing is done by quick-setting plaster to provide support for the impression (Figure 2).

case_images: The impression of the donor ear was made with light body additional silicone, and the impression was poured with the dental stone to get the master cast of the defect site and the cast of the normal ear (Figure 3).
case_images: Fabrication using three piece mould system.

case_images: For this patient, the donor technique was used and the impression was made and filled with modelling wax and later retrieved from the impression (Figure 4(a)). To get the three piece mould, top portion of the dental flask was used as the base, the master cast along with the wax ear pattern was placed on this top portion of the flask, and dental plaster was poured to flush with the surface of the cast leaving no undercuts (Figure 4).

case_images: Care was taken while adding colour, as colour loading will lead to opacity and lifeless appearance (Figure 5).
case_images: Packing using dark and light shades of RTV silicones.
