title: Modified technique to improve fabrication and outcome of definitive orbital prosthesis.
abstract: Facial prostheses are generally fabricated from silicones, which provide life-like appearance and flexibility. The longevity of silicone, however, is limited because of its tendency to support fungal growth, absorb oils and grease, and edge-tearing susceptibility. Polyurethane (PU) liners have been used on the tissue-bearing surface of such prosthesis to improve tear resistance and fungal resistance. Technique sensitivity, discoloration and metamerism are significant limitations of urethane lining. Further, this liner is incorporated during processing of definitive prosthesis, which precludes try-in of tissue surface of prosthesis. This article describes an alternative lining material for fitting surface of definitive orbital prostheses, which could overcome limitations associated with all silicone or PU lined silicone prostheses.
