A study of some mechanical properties of an RTV polydimethylsiloxane for extraoral maxillofacial prostheses.
The construction of facial prostheses simulating the missing tissues as closely as possible is an imperative and demanding task.  Such prostheses will be comprised of parts presenting different mechanical properties attempting to simulate facial tissues.  In this study the mechanical properties of a room temperature vulcanized (RTV) silicone facial elastomer were modified, altering the molecular architecture by controlling the amount of cross-linking.  A wide range of compliance was achieved which enables more lifelike facial prostheses to be made in clinical practice.
