case_images: The patient had undergone exenteration of the left orbital contents due to mucormycosis [Figure 1a]. A radiographic template was fabricated on the diagnostic cast with self-cure acrylic and radiopaque markers in predetermined implant positions in the supraorbital rim, lateral orbital rim, and floor of the orbit [Figure 1b]. Good primary stability with an insertion torque of 40 to 45 N-cm was achieved in all the implants [Figure 1c].

case_images: Casting was done, and the passivity of the fit was checked [Figure 2a]. Flasking of the orbital prosthesis was done with the anterior indexing method [Figure 2b], and before packing of room-temperature-vulcanizing (RTV) silicone primer was applied on the eye shell and acrylic substructure to bond with silicone. Intrinsic stains were applied during the mixing of silicone, and external stains with sealant were applied after finishing and matching the patient's skin color [Figure 2c].

case_images: A large orbital defect was present on the left side with a sufficient bony undercut to aid in the retention of the orbital prosthesis [Figure 3a]. The diagnostic impression of the orbital defect was made with alginate and gauze pieces dipped in plaster of Paris [Figure 3b]. The impression was poured with dental stone [Figure 3c].

case_images: The patient was asked to stare at a distant object, and markings were made from the center of the pupil to the midline of the face and the nasal bridge, according to which the eye shell was fitted in the wax pattern [Figure 4a]. The upper and lower eyelids were sculpted with wax, and the final carving was done [Figure 4b]. A wax pattern trial was conducted on the patient to match the symmetry with the opposite eye [Figure 4c].

case_images: The flask was transferred to boiling water, and a dewaxing procedure was conducted [Figure 5a]. Deflasking was done after the silicone was completely set [Figure 5b]. The color of the prosthesis was secured with the sealant and left for 2 hours [Figure 5c].
