Influence of opacifiers on dimensional stability and detail reproduction of maxillofacial silicone elastomer
(Biomed Central Ltd., 2010-12-16)
Background: We evaluated the influence of chemical disinfection and accelerated aging on the dimensional stability and detail reproduction of a silicone elastomer containing one of two opacifiers.Methods: A total of 90 ...
Effects of pigment, disinfection, and accelerated aging on the hardness and deterioration of a facial silicone elastomer
(Elsevier B.V., 2012-09-01)
The failure of facial prostheses is caused by limitations in their flexibility and durability. Therefore, we evaluated the effects of disinfection and aging on Shore A hardness and deterioration of a facial silicone with ...
