Self Retentive Partial Silicone Auricular Prosthesis: A Case Report


Abstract - An auricular prosthesis may be required for a number of conditions including congenital abnormalities, malignancy and trauma, which result in disfigurement of the pinna. Whatever the cause of the absence of the pinna, it is a significant loss of a prominent part of the face for the person involved. This article describes a simple and cost effective technique for retention of a silicone partial auricular prosthesis. A Fish-bone shaped substructure (FSS) designed and fabricated using orthodontic wire and autopolymerizing acrylic resin, was embedded into the silicone elastomer of a self-retentive silicone prosthesis. The prosthesis is designed to overcome the disadvantages associated with traditionally fabricated prostheses; namely poor structural strength, inadequate retention, poor adaptation and durability over time.

KEY WORDS: Auricular prosthesis; Retention of prosthesis; Prosthesis substructure
