The closure of an abdominal fistula using self- polymerizing silicone rubbers - case study

Abstract

A case is described where an abdominal fistula was temporarily closed using a plug made from dental addition curing silicone rubber impression material. An effective seal was maintained using a stoma flange and a gentle pressure dressing; this still allowed normal gastric function.

An Auricular Bolster Dressing Using Polyvinylsiloxane (PVS) Impression Material

“…PVS impression material is a silicone elastomer consisting of an addition-polymerization reaction between two pastes (a base and an accelerator) which can be dispensed from a dual cartridge. Upon mixing, it forms a polymer material that is clean, odorless, and is readily tolerated when applied to the skin or mucosa (5,6). Modern PVS has a working time of approximately 3-5 minutes before the final set.…”
