Abstract

Five groups of addition silicone impressions (four made in custom autopolymerizing acrylic resin trays and one in stock metal rim-lock trays) were made of a stainless-steel master die. The first group (control group) was not sterilized. The second group was sterilized in an ethylene oxide gas autoclave, the third group in a steam autoclave, and the fourth and fifth groups by immersion for 12 hours in 2% glutaraldehyde. Casts made from each sterilization group were found to be significantly different from control impressions by multivariate analysis of variance and should not be used to fabricate prostheses.
