A 2 month-old female patient underwent surgery for left eyeball enucleation due to a household accident and was referred to Araçatuba Dental School for rehabilitation with ocular prosthesis.
The anophthalmic socket of the patient were examined, and an atresic cavity was observed (Fig. 1), requiring gradual increase with an acrylic expander. For this, the anophthalmic socket impression was obtained using dense silicon (Express; 3M ESPE, St. Paul, Minn, USA). The mold was inserted into a flask for acrylization with colorless acrylic resin. After polymerization, the expander prosthesis was submitted to finishing and polishing, and initially presented the same volume and size of the cavity. After 2 weeks, the patient returned with a more elastic cavity, allowing increase on the expander volume. The expander was relined with pink wax, covering its whole anterior area, favoring a higher vertical and horizontal opening of the eyelids. Following relining and acrylization, the expander prosthesis with new dimensions was installed. Four months later, the patient exhibited satisfactory anophthalmic cavity dimensions, similar to the healthy eye, which allowed proceeding with ocular prosthesis fabrication. …show more content…
in 2012. 12 The impression was performed in two steps. Firstly, a portion of vinylpolysiloxane (VPS) impression material hand-mixed putty (Express; 3M ESPE, St. Paul, Minn, USA), was manipulated and adapted to the patient´s anophthalmic socket until obtaining a superior and inferior palpebral outline similar to contralateral eye. For the second step, low-density VPS was injected onto the internal part of the existing impression. The fitting was removed and the impression precision was verified. The mold was placed into a flask with stone plaster. After plaster crystallization, the flask was opened and the mold
